Can you guys do a GCN does Science video comparing a bike that has a completely gunked drivetrain vs one that is freshly cleaned? Would be pretty cool.

for homemade chain cleaner take 2 toothbrushes with bristles together, use 2 zip ties to secure them, wrap in tape to bristles clean chain and make an extra to lube it. get hack

Just paint it red.

I have almost had a really bad experience with bearings. I was doing a 32 mile race on a 70's road bike. 2 miles from the finish, my front wheel bearings exploded. Oh, I might mention there was a mountain in the middle of the race. Had it happened there. I would have been flung off my bike and 40 mph. Lesson learned - use bike specific grease.

I love your work and you inspire me every day and now I am building a custom road bike with a big road rider thank you

when wiping excess lube from my chain, should i be wiping the sides of the chain (outer plates) or the top (the rollers)

I'm glad bearings was mentioned. I regrease my bearings religiously once a year (more if I drive in wet conditions). Just love the feeling of freshly greased bearings and it only makes sense as they get a lot of use. As for how much lube to use, sure, you can skimp a bit as some is bound to push it's way out and it'll just attract dust, but I do not recommend using only 25%, 50-75% is plenty especially of you regrease every year. 25% just seems like it'll invite wear or (even worse), the dreaded rust monster.

How is the rotor 2inpower? Also what crank length is your inpower?

Hi few questions mate 1 I weigh around 11 stone what should I go for on pressure 2 should I replace the chains which have rusted or de rust them 3 is a tiger quantum 4.0 actually good as it is what I own atm should I upgrade everything possible

I was expecting to see lacing patterns and spoke tightness in the list. Both of these things can cost you more watts than several of the other items. Especially on the rear wheel.

Seriously nice bike Si. Especially like the new Zipp 303s.

I'm catching up on the GCN Videos. Changes I've in the process of making are to the callipers and rotors. Bike as supplied 140mm rotors with cable CX Expert Single pot callipers. Changing to 160mm front rotor and both callipers to Trp spyre. twin piston caliper. Reasoning: 1) twin piston callipers have equal pressure on the rotor giving more equal pad wear, whereas single piston callipers cause a slight bend on the rotor when braking and unequal pad wear. 2) The TRP Sypres are lighter by around 45 grams each 3) Should have better heat dissipation on the front due to larger rotor.

Nice frame!

Hi . Hope hope your are doings good . I have 700Cx 35 bike and needs to change with tyres 700Cx32 mm. so does it required to change the wheel or new tyre(³²) size will fit perfectly? Request your valued guidelines.

I weigh 50kg and run a low pressure of about 50 to 65 PSI on 27x1.25 inch tires. If found it to be a good compromise between smoothness and low rolling resistance. I haven't gotten anything close to a pinch flat either. 90 plus PSI was so harsh that I could literally feel myself slowing down due to rough road textures. Higher pressure doesn't always correspond to higher speed. Especially in the real world.

You should make a video about wheel's bearings :) Cheers from France :D

When I was running 23 tires, I would have the rear about 115, and the front at 110. Now I use 28s, and run 100 rear, 95 front. Me and gear probably comes to 105-110 kg, depends on how much Gatorade I bring.

Absolutely flies until I run out of gear with my maximum 48 X 11.

Hi community, I have a fitness bike a MBK RTB 200 it feels so slow in a 8% gradient and I feel the low gear it has it is no enough. If I get a more recent bike is it going to help. In Strava my average power is 110 watts with a peak of around 900.

Do bikes have bearings? Like for skateboarding there are stainless steel bearings that are good, but you can also shell out a few hundred dollars for ceramic bearings which are extremely smooth. Like it feels like you are ring on slick ice. So you can coast forever. Is there anyhting out there that reduces the amount of friction between the bike tire and axle?

somebody know the name of that rotor crank?

I'm 63kg man on 25c tyres(Specialized Allez Claris) and I was advised to inflate the tyres to 110psi which is said ideal to ride by the mechanic at the Specialized store. Who is correct?

Hey, that is a SRAM etap on your canyon Aeroad rigth? Can you give us a new show around your modified bike?

The writing on my tyres says they are rated for pressures between 110 and 125 psi. I weigh 63 kilos (plus water bottles and all the crap in the saddle bag). So what should I do - ignore what is says on the tyres and keep tyre pressure at something like 93 psi, or stick with the lower recommended limit?

What about 23c×700 what tire pressure will it be??? i use 23c tire front and rear

should i also count in the weight of the bike, bottles, etc. to the rider weight. Because it adds 10 kg, so should i add an extra 3 psi

my best way to make my bike faster was upgrading my bike (lost 4kg there) and going to a sportive nutritionist that helped me get to a more competitive weight (lost 8kg so far, aiming for 10....was a a bit fat) What about lubs, I use a ceramic dry one, would you recommend that for winter? (no rain but fog will get you kind of wet anyway)

What should you do when your tires have a lower recommended psi than what you've recommended?

excellent

So when looking to get lube, I was specifically looking at the one used above, how do I decide which suits me best, some are labeled for dry conditions, some for wet conditions, but you know in this country you can never really depend on the weather.

Many moons ago , back in the 80's I used to ride a Raleigh road bike and pump tyres up with the hand held pump supplied ! Those pumps were useless and was probably cycling with 40 psi 😂 ! Just started cycling since lockdown , done 600 km in 8 weeks on a 5 year old boardman hybrid ! Just found out tyre pressure should be 100 psi , I been pumping upto 60 psi , hopefully my average speed of 25 kmh goes up !

I've read that you can run a fair amount less pressure in your front tyre vs rear. I weigh 63 KG, run 23 mm tyres, and use about 95 in the rear and 90 up front.

You can put about 10% less PSI on the front since there is more weight on the back. However, don't look at it like you will put 100% at the front and 90% at the back, while it's the same thing, it's usually better to pump the back tire to what you need (110 in my case) and then do 10% less than that at the front.
