The best way I can express the setting is: If the same power is put out at 0% and 100% you will cover the same segment in the same time BUT the gears you use will be different. The slider is a virtual cassette IMO...

It’s a gear selector! Plain and simple. If you can’t ride up a hill in Zwift because your front ring(s) are HUGE then lower the Difficulty in Zwift. If your front ring(s) are small then increase difficulty. Zwift gives you things so you don’t have to regear your bike. RIDE ON!

Hi Shane, nice to see that you’ve made a video about something we discussed a few days ago 👍🏻👏🏻

Pretty impressive to be talking 'seemingly easily' with a heart rate of 180! Motivational stuff

As always great video Shane and the best explanation of trainer difficulty I have seen. Much easier to understand.

Great demonstration and it helps me understand. Big difference which should be worth mentioning is the influence on the cadence max and min has.

Watching you hold 350 and not having any difficulty breathing reminds me of watching Beachbody instructor Shaun T talk through the insanity workouts. Excellent video and outstanding job on both of those climbs.

Great stuff as always! Love yer videos!

I did wonder too. 🤔 Thanks for the great vid Shane.

Shane you’re a bloody legend. Simo.

i just started zwift trial on a volt so ill be checking out your vids thanks good content.

Having done similar tests with 100%, 0% and 50% up the Epic KOM, the real benefit that I also see for lower % is the fact you don't run out of gears on the block. Keeps the chain straighter! Reduces the little & big combo for long periods and allows better control of cadence. Leaving at 50% feels right, but for races 20% to reduce the gear changes 👍

There’s a benefit to increased flywheel speed/momentum. It means the whole system is less sensitive to whatever disjoint pedaling style you have. It’s why trainers with tiny flywheels and strong resistance units almost always feel like pedaling through sand. You’re forced to work different muscles (calves/hamstrings) and while the total amount of work is the same, those smaller muscles tend to fatigue / give out faster.

Joop van Roy it doesn't translate to erg mode. That's completely set by restitance of workout or none if freeride. As someone else has commented here, harder the resistance the further up the block you go which generally slows the cadence as well. It's all about the feel :)

@kidsafe

Joop, reducing trainer difficulty allows you to use bigger gear ratios to output the same power/cadence. This has a few effects. As Clive mentioned, you can potentially have your chain in the middle of the cassette more often...it's more efficient, reduces wear on your drivetrain and it's quieter too. Also as I mentioned in a reply, it means the flywheel is spinning faster (has more momentum.) This allows your pedaling to be more free while spinning with high resistance at low flywheel speed forces you to pedal in a rounder style that exhausts smaller muscles like your calves and hamstrings.

I may be wrong, but it still seems like the best way to get folks to understand the slider is to equate it to swapping out the bike's (or trainer's) cassette. Without the slider, you'd be forced to swap cassettes when going, for example, between Volcano Flat and Alpe du Zwift. The slider is like a virtual cassette swap. Just as in the real world, changing a cassette doesn't change the climb's gradient but it certainly changes how you approach the climb.

Nice video. It helped me to understand how it works. Thanks.

Hi Shane another great video.

Nice video, thx! I fully agree that the total energy spent is independent of the trainer difficulty setting. However, in practice there are also transient effects playing a role. With trainer difficulty set at 100%, when I hit a steep section, I do not immediately change to a lighter gear but I keep pedaling at the same cadence and consequently increasing my power output for some seconds. In the same way, after finishing a steep section, I do change to a heavier gear, but there are always some seconds where my power output drops. So for me, with trainer difficulty set at 100%, I see more variation in my power output graph than with training difficulty set at 0%. This does have a negative effect on total performance. It's the reason that "normalized power" has been invented, providing a more realistic way of representing a rider's workload (so also performance) than average power. Of course, it's my own choice to do this "delayed gear shifting", but I could imagine many others do the same.

An interesting test would be to do the kom based on feel and cover up the power data, and see how fast you do it on each setting.

At first, I thought that this setting was useless, but later on I found out that it is exremely helpful. I change it a lot depending on my inteded ride effort.

Great work Shane - hopefully this will clear it up for some people - #hells500

Just tried the same test and I much prefer 0%. Its much easier to keep steady power and cadence. I used to think this was kind of unsporting until I heard one of the In The Pens podcast guys saying they always race with 0%. Sweet.

@stevem2939

Hi Richard ..... Totally agree. 0% flattens the hills but you still have to get watts up BUT at 0% your avatar will fly downhills with no pedal input......therefore 0% is not a flat road so also it does not turn your smart trainer into a dumb trainer. Look at the end of this vid where Shane does a U turn down the hill.........

Cool vid Shane, always wondered if there was a difference. One similar lama lab test that would be interesting would be on pedal stroke analysis using the vectors (or other pedal power meters) testing how heart rate changes with differing pedal styles but generating the same watts. So standing vs sitting vs rounded stroke vs stomping. If you get what I mean? The objective to identify pedalling efficiency. 👍🏼

@kidsafe

5 жыл бұрын

It would identify pedaling efficiency, but only for Lama, and only at the wattages tested and at his current training load. :)

I use a 23 tooth straight block on my drivo and lower the trainer difficulty to about 70 percent. This is to make it similar to a 32 cassette on steep climbs. The drivo is slow to change resistance so having a tighter ratio helps it along making gradient changes and make it less drastic on the drivo. Also this increases flywheel speed in climbing ranges. The drivo is more content to hold me back and not slip on steep sections at low cadence.

Great💪

Cadence changes ! you feel your legs in a different way, because your cadence increases when you slide the difficulty towards 0%. Also the range of available gears you can use on your bike decreases. So it's easier to spin out of the available gears you have on your bike. If you move the slider to 100% your cadence decreases because there is more resistance from the trainer. Also the range of available gears on your bike increases in this instance. So it's harder to spin out of the available gears you have on your bike. You still need to output same wattage to achieve same speed and time goals, but what varies is the cadence at which you ride.

Thanks 😊

I agree. I think of the slider as a virtual cassette change.

Have to say, as a slightly heavier guy (84.8 kg), I like 50%. For races I’ll put it slightly lower so I’m not as shocked by grade changes, basically 40%-ish.

It's the same time because it's the same work, however, the effort is very different, much easier to hold x watts on 1 constant resistance that to respond to changes, effort will shift with gradients and cadence/gearing will follow, that means that different muscles and energy systems will be more or less used

I struggled with a sort of pulsing of difficulty feeling when on long steep climbs like Alpe du Zwift - every two or three revolutions it would spin out a little and then go back to what felt harder. I reached out to the trainer manufacturer for help and they advised backing the trainer difficulty. They told me "The Trainer Difficulty setting doesn't actually make the ride/workout harder or easier. What it actually does is change the amplitude of the resistance changes." I backed it off and hey presto, smother feeling all the way to the top. Lots of people call anything but 100% cheating, but actually, by spinning out a little with the trainer set to 100%, I was actually gaining a moments respite each time, so really, for me 100% was cheating.

Haha 218 it takes me like 10 minutes to get up that damn hill :-)

Am I the only one who keeps it on 100% because I'd rather feel the changes in gradient more as its more immersive and challenging?

We should get a Lama army Jersey on Zwift!

Power

Does Zwift have a chart that shows how the percentage changes affect your relative gearing? For example, if the lowest gear on your cassette is 28, does lowering from 100% to 80% make that a virtual 30 or 32, or does 0% make it a virtual 42 cog? If I was going to lower the percentage, I would want to know what my new gearing is so I can relate it to outdoor riding.

@tobleramone

Why? Just ride and work it out as you go.

So, you could almost simulate the resistance change while in "off" by going up a gear when the incline goes up, because then you need more power to maintain the cadence (getting that leg feel)

Nice test. Would doing it in ERG mode , via a custom workout give a more accurate timing? Not necessarily for difficulty slider, but say for working out how many watts to push to do a climb in X minutes?

Shane's cadence up the hill was 79 rpm @ 100% and 86 rpm @ 0%. For me the trainer difficulty makes it easier on the knees at lower settings.

When going downhill with the difficulty set easier the flywheel never backs off on your tire, so you don't get much of a break in the legs going down hill, in a real life scenario you're probably going to be taking your legs off the pedals sometimes especially in a draft, today I lowered the difficulty almost to zero for a race and pedaling the whole time really burnt the sugar up good for the whole 28 minutes. Setting it lower is ok for TT flat type of courses but for hilly/descents it's not the greatest. You just need to find the sweetspot for your gear ratio, I have a 9speed with a Tacx Vortex and it changes gradients too fast, so I like to keep it around 20%. Even at 50% the gradient changes aren't gradual.

Good vid! Yeah ‘Watts is Watts’ and Zwift bases it’s calculations on Watts (x weight). Be aware though that higher trainer resistance / higher gear at lower cadence (for same Watts) has a different physiological impact than lower resistance/lower gear. The body will fatigue quicker (Watts will drop) with higher resistance. Arguably 🙂

Does a lower setting normalize to make flats a bit more "challenging" gearing-wise? Running into an issue where I can only generate good power on flats in my highest gears. The theory would say I can then drop the trainer difficulty setting and get more power in lower gears on flats and declines. Does that work out that way?

Would the trainer difficulty setting affect FTP test? I mean my Zwift difficulty setting is at max right now. I know it feels harder while riding, but while doing FTP test ERG mode is off, does it mean it will be much harder to reach your FTP goal or not?

I have found that on rides like the AHDR humpday ride I fare better in the after party on 80% trainer difficulty rather than the default of 50% because I can push harder into the resistance on the little rises. Even though the average power required is the same for both settings I think i produce power better when I need to generate torque into little power climbs rather than increase the cadence. I'm sure other people would have opposite experience.

informative comparison.

I find if the resistance is too low, like below 50%, I spin out too easy going into sprints. I prefer about 75-80%. I also will change the setting based on the race if I'm looking for a result.

So, the 'feel' as you say is that you notice the change in grade as it appears to change on the screen? Instead of NO change in 'feel' as the grade changes? I ask as I did my first Zwift session today and wondered why I couldnt feel the transition into the climbs nor the easing as I rolled over the tops of hills. Was set to 50% as standard. Also seemed like I had too much road speed for a given gearing )e.g. I had 51kmh indicated when I was in 39 / 23 and 260W. Anyhoots, I will work it out. Next is to dump the iPad (as it wobbles with the bike) and get an Apple TV or Chrome cast??

Your videos made the purchase way easier) and have noticed my climb times are a bit slower.

Zwift just cares about w/kg (power/weight). So if you've switched to something with 'more correct' power reporting, then the times may be slower or faster. Zwift know what devices people are using (it's in the data channels) but only report 'power', so we don't see it as riders. I find ~80% to be a good balance of hill simulation. *Again, that 80% does not affect the in-game speed, only my feels in the legs.

Would like to see a down hill vid , when racing the higher % is great uphill but down hill is brutal , spin fest and loose ground

Lowering the setting essentially changes your gears on the bike. I live in flat country so my bike gearing isn't set up for 10%+ climbs. Lowering the setting to < 50% alleviates that issue without having to install a new drivetrain just for a virtual ride.

Exactly

I equate the Zwift trainer difficulty settings as 'gears'. At 100%, I'm riding bike with a 53/39 chainring and 11-25 cogs, versus a 52/36 chainrings & 11-32 cogs at 50%. Its really only noticeable on climbs (and descents)

Can you only aero tuck on specific trainers or is it possible regardless of trainer? As long as it's the right percent grade and speed

I’m still a little confused ... I get the watts need to be the same but does the higher difficulty level mean that it’s harder on your legs? I guess that’s when you work through the gears right to make it easier? do you have a general preferred setting that’s best of both worlds? ... or a preferred setting for training vs racing vs a more chilled ride?

I go 100% for races. Climbs are where the attacks generally happen and you want the trainer to give you that feedback rather than having to shift gears to put out more power. If you ride at 0% diff and don't shift on the grades the pack will fly right past you.

question: at around 0.28 in the video, we can see a choice for routes. Is that gone now in ZWIFT ? I dont see this anymore. I only see the default and I have to use the Zwift companion app to select the other directions to see where it would lead me

It doesn't make a difference with a huge asterisk that supposes you'll be able to turn the cranks at a reasonable cadence. This is crucial in races where you want to keep your glycogen reserves as high as possible for the final

I leave it at 100% with a 50/34 and 11-32 (2x9 Sora set up).... If I tackle the Stelvio or Ventoux on Wahoo RGT I'll consider lowering TD to 75% which is to take into consideration that if I ever did these mountains in reality I'd probably swap out for an 11/36 or even 11/40 cassette.... I don't mind working the gears on a hilly course- keeps you focussed on the view ahead and the profile, and probably ensures a more fair and even wear on the cassette rather than sticking to just a few gears (or worse in ERG, one gear....)

In theory, if I increase the difficulty slider in Zwift this would effectively put me back into a more RL range of gears, correct? I didn't touch my small chainring on my first ride in London.

I have almost 52 years of martial arts in me, a ton of wear and tear and surgeries on my knees. Regardless I dream of hitting a steady 300w and currently on 13 rides on Zwift I average only 130W. Yesterday I rode my first race 12.5 miles with 700+ climb. At start of race 37 guys shot like rockets in 6 seconds vanished from my sight. I took off with another guy who took off with me and at the end he was 5 minutes ahead of me. I finished in 39th place with 52 people behind me. My difficulty level was set to 75% from the standard 50%. In the Zwift videos I heard the higher you place the bar the more realistic the climbs will me. I cannot believe I have no legs left after so much martial art dedication and I still hope to do positively good as I always set sights on realism at my age but also prove to myself I am not average. Thank you for reading

lowering the difficulty pretty much makes you increase your RPM's. you have to produce the same wattage, so lowering the difficulty means upping the RPM's. your example here proved that too...you were doing 73RPMs on the first go, then 86 on the second go at the same location of the climb and producing the same wattage and virtual speed.

The alp is a grind and best time is 69 minutes. My power would decrease as the climb progressed. Today I did it with the slider moved to about 75% to simulate the feel of an 11/32. I beat my time by 2 minutes and kept my power up almost until the end. This on the back of 25 laps of the volcano circuit the day before. So with less than fresh legs I still best my best time. I guess my hang up is if it feels easier in the legs I should be able to put more power down which increases my speed.

Slower cadence recruits muscles differently, and you should be more efficient when not grinding. So a long climb should be easier, in that sense, on the easier trainer setting despite the fact that the same wattage will get you the same time up Alpe du Zwift no matter what setting you use.

My avatar even adopted a tuck position !!! This must count as a massive advantage for anyone in a race @ 0% trainer diff......... or even users with dumb trainers and power meters. Have you experienced the same ?? Am I missing something ?? I have a Tacx Neo.........Cheers Steve

My understanding is that trainer difficulty can adjust how you produce those watts ( torque x cadence). 100% you need more torque and less cadence (check video, watts and speed are the same but the mean rpm are like 70-80 on 100% and 80-90 on 0%), at 0% you need more cadence. Time, speed and wattage will be the same. This can affect your gearing but that is how I understand it. Even his heart rate was aprox. the same. I started using Zwift (and a trainer) like 2 weeks/1month, I ride at the default 50%, being a heavy rider I use more power on the legs rather than rpm. I notice that my gears always run out, I tend to use the heavier gears (big ring in the front, smallers at the back). I will try to adjust the trainer difficulty so I can take more advantage of my gears Correct me if I’m wrong, I’m new to this and only searched this now. If my trainer only makes 6% incline, am I riding on a discount everytime Zwift goes above 6%?

What this shows is that watts are watts when it comes to in-game speed. When it comes to how you as a rider produce those watts, that's very subjective. Some riders are more efficient at lower RPM, some at higher RPM. If you're on a trainer that can only reach 6% simulation, that's all the physical resistance you'll feel. In game your avatar is subjected to the gradients as shown on screen and will be slower at 12% than 6% at the same power.

Big argument on Zwift Riders (FB) after the Ineos race up the Alpe. Someone was claiming Rohan won because he had is difficulty slider set to ZERO (but had no proof). Needless to say there was a lot of fun being had in the responses. Someone ultimately posted a link to this video, and it seems to have quieted things down.

Jim, watts are watts in the virtual world. Correct. However the physical toll is different in the real world, especially when a large enough flywheel (or simulated flywheel) is used. That momentum functions as a buffer/filter that smooths out your power phases. Eliminating micro-accelerations in your pedaling ultimately slows the rate of fatigue. If Rohan was using a low or even zero setting on TD, I could almost guarantee you his time would be better on AdZ because flat terrain at high speed is where he puts out his best power. He is adapted to those kinds of efforts. Basically he'd be able to do, say, 420W up AdZ with TD at 0%, but maybe only 395W with TD at 100%. Something like that.

What difference does it make? If you are out on the road do you have to have a specific cassette on your bike? No. You can do what you like. It's when you start cheating about your height and your weight that you are breaking the rules.

@@user-fk8rb8ue5h If going all out on AdZ it certainly can make a difference. Like @yoog mentions there’s fatigue In micro-accelerations from many grade and gear changes. Also, at some extreme grades like 16% I cannot keep a 80 rpm up, so I’m adding to my large muscle torque fatigue and forcing smaller muscles to jump in.

Hi Shane what gearing are you using in the video? And what gearing are you using ridning on Zwift Mountions do you use the slider for trainer difficulty? Love watching your vidieos on the Channel.

I can't recall to be honest. Likely a 53/39 on the front.... 11-25 on the rear. The slider is usually at 100% for me on Zwift for my riding.

Correct. See my video here on this: kzread.info/dash/bejne/aXWOwcxpeKeqlbQ.html

Having watched this video I did notice that with trainer difficulty at Max you were averaging 350 watts and 70-80rpm cadence and speeds of approx 19-20kph, with difficulty at ‘0’ your average cadence was 80-89 rpm to maintain the 350watts and HR was higher

​@@cornishalps9870 Hard to make conclusion on that. For me i prefer 70-75 rpm cadence on the climb. it actually lower the heart rate down compare to 90 rpm, for a condition you don't climb too much over FTP to fatigue out the leg too fast. Try on Ven-top 90+ minutes climb and see...

It is a way of making the cassette more flexible.

Careful Shane. You'll give ZA ideas. 1 minute intervals was bad enough. Next thing you know, we'll be doing 2 minutes at 120%, 130%, 140% and 2 free rides hard as we can go.

Sorry if this was addressed earlier, but have you tried using Instant instead of 3 sec average for power display? I find the feedback is better for maintaining a given power during intervals which might seem counterintuitive, but the smoothing creates a lag that I end up chasing more. The refresh rate on the display seems the same, just more accurate.

This does not have any impact on the in-game speed or pacing. 3s average is simply a visual change to what's shown on screen. Workout mode in Zwift will only show 1s average at this point. It ignores the setting.

I'm using a wahoo kikr V5. I don't seem to have the option to adjust in my zwift setting. Am I missing something? Is this not an option with this trainer?

So if the wattage and time stayed the same, but trainer feel changed, does that mean cadence also changed?

Only if the same gear was used. A mechanical analogy would be riding up with a T39 chainring vs a T34 chainring

Question: Is the "Trainer Difficulty" setting the same as the "Incline" setting in the Zwift Companion App?? Are they linked? Meaning if you change one, does it change the other? Or are they two different settings that do something different? If so, how are they different? Thanks for any responses!

@gplama

No. Incline I believe is ‘level mode’ within a workout which turns your trainer into a resistance unit with 10(?) levels of resistance. Trainers usually have SIM, ERG, and Level modes.

Hi Shane, what if you set the trainer difficulty to 0 and join a zwift race or trying to set a PR for segment. would that be easier (for longer ride duration)?

@gplama

It might be subjectively easier... but that's to do with how I produce the power. The purpose of this video was to show Zwift doesn't care what the slider is set to. You still have to produce the power for the same times.

You didn't say which you liked more. Any preference?

Hi. I have Elite XR-T smart trainer that I use with my mtb. I am new in using zwift and last week I tried to race for my first time. I noticed that I am to slow on flats and descents, even if I have very high cadence. beside that, the trainer resistance is to low. I suppose that is because of my 1x12 drivetrain which has 34 teeth front chainring and 11 teeth smallest cassette cog on rear. Am I right? Can I change that if I increase trainer difficulty level? I mean, will my speed increase on same cadence if I increase trainer difficulty level ? Thank you!

Is it okay to have a really high cadence when pushing high watts? I usually get to above 100 cadence and don't get too tired when pushing over 220 watts, I find that i can old the watts for longer with higher cadences

Sure, if that works for you.

Interesting. What effect would the trainer slide have on a non ERG mode trainer if any? Would it for instance, calculate the riders profile and slow the virtual wheel speed if set to 100%? Asking as my 5yr old daughter is hooked using it for her monthly Race at your own pace medal. She's using a 20" wheel and pedalling like merry to achieve her 25 mile goals each month particularly when the road goes up on Zwift.

There is no slider for non smart trainers.

I've seen a video that states that adjusting the difficulty slider down from 100% is just like adding more teeth to your cassette (so it's just like virtually swapping out your cassette). Seems to be the easiest way to think about it.

That's an easy way to think about it, yes. Technically what's happening is a little different.

Does it affect going downhill as well? My 8-speed chain doesn't work great with the 10 or 11-speed cassettes in my studio and I can't use the bottom half of the cassette, I.e. 11-16.

Shane, just getting into trainers and indoor biking. Budget at the moment forced me to start with Bkool go and an average 10 speed bicycle. On this setup although I peddle very fast and get good rpm my watts are relatively low and my bike travels and an unrealistic slower than expected speed. Other bikers pass me all day long. Any idea what I need to do to correct this ? is it just poor equipment or is there a setting somewhere I can tinker with ?
