I'd assume that 80% of people living in Europe (and yes, including the UK and Ireland) would have to transport their gravel bike somewhere by car first to exclusively ride on gravel. If you live in a city, gravel is kinda rare. In suburbia and even many more rural areas with smaller towns, you'd have to take huge detours all the time to exclusively stay on gravel or dirt roads. So by your logic, nearly everyone should go 2x on a gravel bike.

Great video guys. My reason for 1x: I don't race anymore and I don't compete with my friends, therefore I haven't needed close ratio gears; I don't need to be shifting all the time; I'm especially not a fan of shifting between front sprockets; I like riding fat tires; 1x is all I've had for the past year now and it has suited my style perfectly.

How easy/hard is it to convert a gravel bike from 1x to 2x or vice versa? I'm about to buy my first gravel bike (im a mtb rider branching out into road riding) and i'm super torn and don't want to be locked in. My first bike was a 2x8 hard tail which i loved but front derailleur gave the most grief. I now ride a fuel ex 5 (1x12) which I love for the trail, but am worried about doing 1x for gravel b/c of the decreased range...

I was very much a road cyclist only until I spent some time in Tuscany in the early 90s. I was "forced" to join a group of MTB riders for a few days, so I bought one myself and got hooked! In those days it was 3x7 Shimano XT - brilliant, the number of gears and those crawler gears really needed. I then designed a so-called gravel bike with XTR centrepulls on a road frame, allowing me to put seriously wider tyres and tubulars (cyclocross) while using 700 wheels. I set it up with 2x8 which limited the gearing (clutch gears not being available). Gave away My mTBs - a mistake. Now, spending 4 months in the mountains each year I soon found that my "allround" bike had limitations. This led to me reverting to 3x8 Shimano XT. Still a compromise, so I have just bought a Storck Gravel Bike, all carbon, 8kg and offers a good position, something many riders ignore. Manoeuvrable, great frame for climbing and road work where it is very slick. The Ultegra changing (2x11) is quick, positive and it suits me! Tyre choice is often the most important factor. I have been experimenting with newer tyre types like the Schwalbe range, Continental Gravel King etc and they transform any bike on stony tracks. The best tyres were the tubular cyclocross, but are pricey, and you will get punctures! Have also used Conntinental 4000 - amazingly capable if I am too lazy to change tyres! The Schwalbe 700/32 are a revelation in bends and ability to hold the line, Gravelking 700/35 have exceptional traction, so for me, tyres, lightweight and the right gearing wins - but as always in cycling there is a choice. One last point, my cycling started with English hand-made frames, like Woodrup or Ellis Briggs - Campy changing was superb, gears a little restricted! My first Alpine experience was on 51/45- 13-24 - hard work!

This channel is so helpful to someone like me as I’m not a cyclist like you guys who are pro’s. I’m going to get a titanium gravel bike as I’m retiring and I want to make an informed a decision as possible and your information is really helping me do this - thank you 👍🏻🏴󠁧󠁢󠁷󠁬󠁳󠁿

What about just 1x but bigger? Right now I have a 42 GRX... I am thinking to replace it with a 46, 48. What you think guys?

36/46 11-32 works great on my Boone X. I like to push hard gears on climbs so this is perfect for someone who likes to push a harder gear up steep climbs. Great vid GCN!

I live in a fairly flat area, so my next build will be a 1x. Simplicity, aesthetic, less maintenance are all key its future use as a commuter and occasional off road gravel adventures!

I initially went with 1x on my gravel bike because it got me the low end grunt I needed. This was a few years ago, when 2x meant 34x32 was as low as you could go, and there is a 1.6Km 16% climb on a favorite route that I barely make it up with my 42/10-42 1x setup. Now that 2x gravel bikes don't mean making do with road drivetrains, I'd probably make a different choice today. I really miss having the top end, and the paved sections always make me feel like I'm caught between cogs. I can't complain with how absolutely bulletproof a 1x setup is, though. It's nice having the reliability of a drivetrain like my mountain bikes on the washboarded country roads I frequent. Gravel was also the gateway to road biking for this mountain biker, and I've seen it work the other way around. Not enough people talk about how these do it all bikes wind up expanding riders into different disciplines.

I tried 1x for 2 yrs to test it out running alongside a couple 2x all-road bikes too with Ultegra. I liked it at times for the training benefit to force low-cadence spin, or high spin, after that, all compromises. I just sold all the SRAM Rival 1x and am back to ALL 2x, and that bike is now GRX 2x 48/31. Way way more versatile w 48/31 & 11-30/32/34 cassettes, way way more. And no compromises which is what you get the most of with 1x: missing gears, constant cadence and gear hunting, funky loud-ass shifters, and spinning out on downhills at 33mph. F that. And comically one of the selling points of 1x is how quiet they are!! Ha! Show me a shifter that's louder than a SRAM 1x HRD, you can't , LOUD AF. The take home? GRX is the answer that SRAM missed the mark on BY A MILE with eAXS with no mechanical option, HD drivers, 12-speeds when 11 is totally awesome, and e-everything with prices through the roof, wtf?! . Again, F that. Bravo Shimano, Shimano for the win !!

I got a mountain bike with 1x last june and loved it. I stopped riding year’s ago and have trail run last 12yrs. So to my surprise from my previous 3x mtb 1995 bike I loved it. I also have a 2x trek domane 50x34 up front and 11-34 in back, but just ordered a 1xGRX blackheart titanium and am excited to ride that!

Where you are riding is important. If you live/ride in the area where you can spend 80% of time on gravel, go with 1x. If you have to spend close to 50% (or more) linking gravel on paved roads, 2x is a lot more comfortable and efficient.

Very helpful video. Thanks again for great content GCN.

This is quite old topic, however I watched this video now just to assure myself I choose right. I own 1by Canyon gravel bike and I love it after 2500 km I drove last year. I love the simplicity in all ways - aesthetic is wonderful, simple clean design; changing gears is awesome simple, as you said, you don't want to spend your life changing gears :). Last but not least cleaning and service is unspeakable simple. So this was my choice :). Of course there are compromises, but I can live with them. A little thing about saving grams - you probably don't save any grams with 1by, because of weight increase thanks to bigger and heavier cassette within 1by setup. Have wonderful kilometres!

One of the main reasons for buying my Koga Colmaro Allroad was its 1x drivetrain. I love the uncluttered esthaetics, simple operation and easier cleaning over 2x. Most of my kms are aboard my 8-speed gear hub commuter, so 1x11 is plenty enough gears for me. It got me over the brutal Côte des Hézalles out of Trois-Ponts as well, so I wouldn't know why I would need more gears.

Have started researching for my bike #2, which will 90% certainly be a gravel bike. Moving up from a basic hybrid I'm feeling super out of my depth with all the different tech, but this is very helpful!! I do love the minimalistic look of a 1x, not to mention the prospect of easier maintenance + I rarely hit speeds beyond 40k/h anyway, so definitely leaning that way.

Good stick action there Si, holding up the bikes! 😀

I just ordered a 2021 Marin Gestalt X-11 gravel bike. I chose this bike because of the relaxed geometry and because it seems to be a great all around bike. I can take it on gentle trails as well as on asphalt. I also wanted a bike with a 1X Groupset because it is SIMPLER overall and therefore requiring less maintenance. I don't plan on going over 60K any time soon. Less adjustments means more riding. Thank you for the video and explaining the pros & cons of both groupsets!!!

this video is absolutely beautifully photographed. well done team.

1x forever!! When I got my first geared bike back in 95 when I was 12 years old I hated the front derailleur. Even then I thought why dont they just put more gears in the back and just have one up front. Needless to say I was ecstatic when 1x setups came out. This left leg amputee has all the gearing needed with a 36t chainring and a 10-46 cassette

What are your ratios?

Just got a new Ibis Hakka with a one by. Love it, just not missing the extra gears and the shifting is great.

You sir, do such a great job on your channel. For me it is 1x ftw. Riding pave on rolling terrain I used to shift chain rings as much as rear derailleur. Annoying. So much easier to keep a 1x chain ring clean and riding smoothly. With direct mount chain ring I can quickly swap to something like a 34 T if I am going up jeep roads to 12,000 ft. But generally a 38 T chain ring with 10-42 cassette gets me most everywhere. Dropper activation using left 'shifter' is great for where I live and ride, and it keeps my neck much happier on descents as well as boosting the fun factor. I ride pave, dirt roads, with the occasional rocky steep challenging single track.

1x is worse for backpedaling, they say. I've never noticed it. Though what I like about the 2x setup is the "get out of jail" card. If you have to do a sudden stop (maybe because there's a car coming at an intersection), going into a lower gear means you have to do several shifts with the shift cable tightening, and that means the rear derailleur have to work harder against it's own spring, thus you can't really shift under a lot of load and the acceleration from that sudden stop will be sluggish. If you have a 2x you can just pop into the smaller chain ring, and the shift can be done under a higher load.

This is actually a very important point. For me this is the reason I would more likely abandon rear derailleur as opposed to a front one of it was an option. Also when riding in bad weather conditions and not looking for the bike condition all time, one of derraliours may break during the ride.

I went for the 2x that I did because it best matched my fitness and riding patterns. I had a 3x as my first bike getting into cycling, and I needed all 3 starting out. For this season, I looked at the gears I actually used (didn't need smallest ring anymore), and found the Shimano 105 group set was a perfect match.

I used to look down on gravel riding at Roadies who wanted to ride MTB but didn't want to actually get flat bars. However, I demoed a giant Revolt carbon on my favorite trails yesterday and I'm sold. Gravel and MTB are totally different experiences on the same trail. One is about going as fast and as hard as possible, one is about being as precise smooth as possible. Needless to say I spent the whole demo day on a gravel bike and now looking to buy one. I'll probably go with a 2x.

I was riding a GRX 1x on my Kinesis Tripster and this was very good as I was using it almost entirely off road. I don’t do so much road now, so sold the road bike and started using the Tripster as my road bike. It soon became apparent that 1x wasn’t working and so converted it to 2x, much better. Now does gravel & road. I also no longer use the Tripster as my light duty mountain bike as I now have a Specialized Tero 4 e-mountain bike for that job, so much fun.

this was a great vid to help me determine next steps in building up a Bombtrack Hook Ext-C and really want to go 2x (b/c i;m old and like choices), but having never ridden a 1x, and wanting to squeeze a 2.1 tire in it, i may keep the 1x set up as the previous owner had it and try out a dropper post left shifter as well.

I’ve got a Scott hard tail MTB with 2x and Cannondale road bike with 2x. I recently bought the beautiful Rondo Ruut Ti with 1x GRX. I love it and I love looking at it.

Still running 3x on my mountain bike. Up steep hills, fast on the flats and down hills, and everything in between. Always got a ratio where I want it.

I think they are both good choices. It just depends on what you will use each set up for. I personally like a 1x for cross and mtb and 2x for road and gravel. There are times where a 1x set up is better for gravel and it depends on the conditions you are riding in. If it’s wet and muddy 1x but if it dry and fast 2x

I run a 105 R7000 (11-34 though) setup on my gravel bike, bought it just before GRX was released so had no real choice in the matter. Having said that I do love the easy and clean shifting it provides

I agree with what Si said about too close gears. Tried 12-25 cassette (11s) on my bike I use for gravel and I ended up changing gear twice when I wanted to shift down or up (when being in the middle of the cassette, 1 tooth difference just isn't enough).

Nice job on the review with excellent pros and cons. If I have to use a chain I vote for 1X setups with the rear cassette geared for the type of riding expected. Frankly I feel all chain drive bikes in over $1000 bikes should have been long eliminated and replaced with a rear hub or axle with embedded gears in the hub or a v-grove constantly variable e-gear ratio driven belt drive. I've seen the internal rear hub gears like the Shimano Nexus C3000 but it appears the mechanical toughness is still an issue. I expect e-bikes to start using these internal hubs and hopefully that drives innovation. Lets get rid of these 1900's tech chains!

5:37 and you can impress yourself with your super high cadence trying to keep up with your mates with 2x on paved descents, and your bulging quads grinding up +12% hills

Really enjoyed watching this. Really well presented and very informative and it made me laugh, bonus. Keep up the good work GCN.

All great stuff in this video!! My questions are answered and more. Cheers

I find another advantage of 2x is that, when accelerating from a stop, the front chainring shift is quicker to dump to a much larger gear both because it’s a major change in one increment, and because it’s a cable pull, in a way that I find you can still apply a bit of power during the change. That might hardly ever come up on trails but for commuting in a city it’s the norm. That said Ive been using 1x anyway . Totally agree to me it does look better.

You're lucky. I need the lower gearing for the 14-18% climbs in my area. There's also one hill near my home that's in the 16-28% range, but I avoid that one.

Love the humor of life lessons learned. Keeping being yourself Si

QUESTION: When should I change gears? -- What cassette gear should I be in when I change my chainring gear up or down? -- Would it depend on which chain ring I started in? -- Would the choice be different when I'm climbing, descending, sprinting, or cruising? -- I ride a 'gravel' bike with a 2x setup. -- This is my setup: Chainring == 48/32 | Cassette == 32,28,25,22,20,18,16,14,13,12,11. -- It seems that the best cruise cassette gear is the 14. -- The 48x18 is equivalent to the 32x12. -- I hope you can help me sort this out. -- Love the show. -- Keep up the great work!

N + 1! If you have a 1x bike, get a bike with a 2x setup. If you have a bike with a 2x setup get a bike with 1x....simple math!

@@MrJay_White Yeah, it's got a bit of drag but the monster truck feel is fun and being able to ride in any conditions is great. My particular fat bike was built 2x so that makes it easier :) The previous owner just took off a chainring and swapped some of the spacers on the BB cups so 2x was a matter of going back. It's got an english thread and 24mm crank spindle so the BB is off the shelf Shimano, just a wider sleeve in the middle that came with the bike. SRAM also makes 2x GXP cranks with fatbike width that would do it with a swap of BB cups.

Thank you for this excellent explanation in depth. Got a Rose Pro Cross GRX RX400 incoming. I felt a litte uncertain because everybody said: Naa, go with the 1x. Finally good that I sticked with the RX400 2x due to two reasons: First I come from the Cross/ Fitness Bike section and ride Deore XT 3/10-11-34, therefore 2x feels right. Second many manufacturers sell the lever for the f-derailleur as "only brake" version. If you then want to use it e.g. for your seastpost your left hanging...

The biggest advantage of 1x for me is that I can easily move the gear range up or down as needed. There is a large selection of chain rings, you're just limited by the frame (which can be a significant limitation). Unfortunately, the selection of 2x chainrings is quite limited. For example, the excellent 28-44 is almost dead. Shimano used to have that combination for XC MTBs. It actually offers bigger gear range than 31-48. And with a 11-40 cassette (IIRC), it was a beast. Personally, I would take a 2x with a wider range cassette (to tackle steep terrain), which the GRX unfortunately doesn't officially support.

1X was designed for Full Suspension MTBs and in that role it works because front derailleurs are a problem (note all of the other technologies that are popping up to "recreate" the front derailer). In other roles it has its problems. 1X has fewer gear ratios to choose from and the angles that the chain is forced to work on causes a few %'s power loss. So if I was racing anything other than MTB downhill or enduro (and MAYBE CX where there are typically not long high speed sections), I'd be on a 2X. Typically, SRAM (and other bike makers) have tried to market this deficiency as an asset and because the bike industry needs to sell crap and 1X is cheaper to produce so why not move everybody to 1X for a few years and then have the big reveal that 2X is actually more efficient sometime in the mid 2020s and get everyone to go back. Sounds like a plan to me. Let me know when they get that Ceramic Speed chainless drive train reliably working for mass production and then I'll switch to 1X.

Except with GRX, you can now get more low range than the typical 1x setup. My 1x bike is 42T with a 10-42 cassette. I'm now seeing guys running 2x gravel bikes with a 11-36 cassette and 46/30 crankset. You wouldn't have to hike up the steep off-road sections AND still have the top end and closer ratios. That's a ridiculous amount of range that is making this SRAM guy reconsider his approach.

@@noodlesatf I'm happy to report that I am already using the GRX and it's a big difference to my road gearing. While the cranks on both my bikes are 50-34, the cross bike is running an 11-32. I imagine I could go bigger, but I am just a simple lowland for-fun cross-rider. The jumps between the gears will take some getting used to. But so far I can only recommend the GRX.

I like it that you speak of how important the looks of the bike are. Whilst holding a bike with a paint job reminiscent of a bowl of sick.

finally a good one, Kudos GCN with the 11s 12s speed coming along, I*ve found so far that they could play more with number of teeth, especially when I refix older bikes and only have 9s or 10s speeds. and you could talk more about the chaincatcher, it might not be a big deal, but your sure to uncatch the chain on a sunny day and no gloves :-) cheers

This video is really good. Good analysis, entertaining, and funny. Presenter has charismatic personality. Well done.

All three of my bikes are 1x. One of which I recently converted from a triple to proper 1x with a wide ratio cassette and narrow wide chainring. My other two bikes were 1x as stock and using them made me want to make the switch on my triple. I will never go back to having a front mech. The unnecessary process of constantly shifting up and down at the front just to get the full use of the cassette without chin rub at the front is enough of a reason for me. The added perk though is that off roading in the winter filth means that there are a lot less mechanical components to get gunged up and liberally cleaned at the end of every ride.

I was in love with my 1x GRX Di2, but then I started getting more serious in gravel and road riding, and the jumps between the gears were too much and so my cadence

Even though there is gear ratio overlap, I love my 46/36T with 11-32t cassette 2X set up. It's a fairly traditional cyclocross set up, true. But, I find it manages to get me through a massive variety of tarmac, gravel & cyclocross terrain with nice close shifts. You have to be going up really steep climbs, or ripping down a descent while pedaling hard to feel the ends of the gear range. I can see that 1X might be nice on a purely race oriented cyclocross build though!

Thanks for the great insight!! I was so on the fence about 1 x vs 2 x. I ride gravel but I have road to contend with before hand. Plus I want to have the option to put bigger tires on my gravel down the road I have a 1 x on my scott 940 mtb and I am liking both the aesthetics and the efficiency of the shifting plus I am a notorious chain crosser so it works best for my shifting any old way I like especially on the fly, I am not proud of it but I have been called out on it on several occasions. lol

2x - practicality over fashion - for me. While I like the look of the 1x and running it on my MTBs for many years I bought my Orbea Terra with 2x GRX. I don’t have a dedicated road bike so the Terra is double duty and I cannot stand the 1x’s large jumps between gears when riding on tarmac. Also, 2x gives a wider range, 46/30 crankset with 11-34 cassette has everything I need while 1x would be too much compromise for me. I know 1x is perfect for many, and I think the two will live side by side in the ‘gravel future’. Tire clearance with 2x GRX is a non-issue, I can run 45mm tires with ample clearance in the lowest gear. If I need wider tires I use my MTB.

I use my gravel bike for bikepacking and long distance and when I do this it's usually around 85% tarmac or very compact gravel.

Mullet setup ftw! Eagle mtb rear end with Force eTap up front. The 10 tooth cog buys you 4 teeth up front, so you can get both a harder AND and easier gear than 2x setups. And, like Si said at 9:45, the gaps are welcomed off-road and not horrible in the on-road sections.

Roadbike: 2x compact, Gravel/Winterbike: 1x1 Singlespeed, absolutely hassle free in dirt and mud. Nice side effect: very good training in winter time for endurance and power. After the winter I am much more fit than my buddies who cycle indoors and went to Spain for two weeks in a training camp.

Right? I generally only use my 34t inner chainring on my Emonda on climbs that are stupid steep... 15% or more. I do have a tendency to cross chain big/big though. When my gravel bike is in "road mode" with slicks on it I get along very nicely on a 44t 1x and a 11-42 11spd cassette. I've been known to occasionally climb 22% grades on that thing. If I'm off road in hilly country, I down size my front chainring to a 40t And if you do go 1x... narrow wide is the sex. You need that

It might sound old-fashioned - but I loooove my 3x groupset at my mountainbike. If I compare it to the 2x groupset of my second mountainbike, it has soo many advantages: 1. I can stay mainly on the middle front gear and just fine-adjust with the back gears. With the 2x groupset, I always have to shift up and down, depending in wich gear I am. 2. When it is really step or I ride fast I have a wider range 3. the gear-steps are much smaller, so I can always find the right gear for my cadence. The little extra weight is totally worth the comfort. And my front shift never failed in 15 years of bike riding, it is always the back. I don't understand the tendence to buy 1x or 2x groupsets (just because of weight and optics?)

I agree that 2x is awkward on MTB, because you have to cross-shift all the time to find the right gear. Maybe paradoxically, rather than 2x, a 1x set with a modern wide range cassette might give you an experience much closer the 3x. Imagine the single front cog on an 1x being like your current middle cog on 3x, and a large 12-cassette (they make monstrosities like 9-52 now) gives enough range and small enough steps that you never need the two other front cogs. But I also do not see anything wrong about 3x sets, and am a little angry that manufacturers stopped developing them and are slowly stopping to produce them. It is again one of the cases when manufacturers forcibly remove options from the customer. This is happening in all industries recently.
