trialsiain Posted August 28, 2013 Report Share Posted August 28, 2013 Hi are 165mm cranks best for mods ? im 5ft 11 if height makes any difference... im stuck between 160 and 165 Link to comment Share on other sites More sharing options...
Blake Posted August 28, 2013 Report Share Posted August 28, 2013 I used to run 170's on a my mod, but now run 165's and can say I much prefer it, best crank length. However when riding my friends 160 cranks I can't help but feel they're a bit too short, but I am around 6'3 so you may prefer them Link to comment Share on other sites More sharing options...

AdamR28 Posted August 28, 2013 Report Share Posted August 28, 2013 There is no 'right' really, it's a personal thing - 175s for me. Link to comment Share on other sites More sharing options...

There is no 'right' really, it's a personal thing - 175s for me. and i meant like what is the most commonly used Link to comment Share on other sites More sharing options...
Blake Posted August 28, 2013 Report Share Posted August 28, 2013 Also depends what type of riding you wanna do shorter would be better for street riding as more power = bigger gaps but longer for more torque when on rocks Link to comment Share on other sites More sharing options...

Jake. Posted August 28, 2013 Report Share Posted August 28, 2013 I used 175s on mod and liked it. Just get what you think will suit you most for the riding you so. Do * Link to comment Share on other sites More sharing options...
dave33 Posted August 29, 2013 Report Share Posted August 29, 2013 160mm it's not a really a personal thing, more of a maths thing. Link to comment Share on other sites More sharing options...
aener Posted August 29, 2013 Report Share Posted August 29, 2013 (edited) (175 / 26) * 20 = 134.6 It's not a maths thing.Edit:Also depends what type of riding you wanna do shorter would be better for street riding as more power = bigger gaps but longer for more torque when on rocksWhat the hell? In what universe does less leverage equate to more power? Edited August 29, 2013 by aener 1 Link to comment Share on other sites More sharing options...
bing Posted August 29, 2013 Report Share Posted August 29, 2013 I ran 175's on my mod, felt a bit lumbering to be honest. Changed to 165's, changed the feel of it instantly for the better. Felt better of static hopping about stuff as well at comps Link to comment Share on other sites More sharing options...
SamKidney Posted August 29, 2013 Report Share Posted August 29, 2013 170's on all of my mods. I found 160's too short. Link to comment Share on other sites More sharing options...
trialsiain Posted August 29, 2013 Author Report Share Posted August 29, 2013 So 165s must be juuuust right Link to comment Share on other sites More sharing options...
dave33 Posted August 30, 2013 Report Share Posted August 30, 2013 (175 / 26) * 20 = 134.6 It's not a maths thing. Power= speed +strength. No point having all the power in the world only to be to slow Trials is an explosive sport Edit:What the hell? In what universe does less leverage equate to more power?

Blake Posted August 30, 2013 Report Share Posted August 30, 2013 Just always found shorter cranks easier to gap with, as the gear ratio feels harder. Link to comment Share on other sites More sharing options...

No point having all the power in the world only to be to slow Trials is an explosive sport So having shorter cranks increases your gear ratio now? Shorter cranks won't make you go faster. It'll mean your feet have less distance to travel and you'll have less leverage, but it won't make you go faster or have more "power" (your definition of which, by the way, is offensively incorrect).

Lol did I say any thing about going faster ? Longer crank means your foot needs to move a longer distance. Meaning on a run up while your traveling at the same speed you legs need to move further and faster. When you do the last two pedal rotations you then need to accelerate your leg speed for the final kick to propel forwards and upwards. That takes alot more strength. Your argument seems to assume that the only method of proposition in trials comes from your legs. When you jump your using alot more muscle groups. Yes I agree longer gives you more leverage. Might help on a short run up on a steep slope to start moving. But in trials you want to be accelerating more and more the closer you get to the object. No point in slowing down You also can start closer and still get the same rotations in with shorter cranks. There is a simalar argument in track cycling Link to comment Share on other sites More sharing options...

Jake. Posted August 30, 2013 Report Share Posted August 30, 2013 This reminds me exactly of the topic with the chain I wanted to buy. The lads already decided what length cranks he wants, no point carrying this discussion on. 1 Link to comment Share on other sites More sharing options...
Luke Rainbird Posted August 30, 2013 Report Share Posted August 30, 2013 What ? Your the one trolling. Nope. If I was trolling I'd point out that you used incorrect grammar and that it should be "you're" in this instance. But I'm not trolling so I won't do that. Trolling would be making a statement such as "did I say anything about going faster?" implying that leg/foot speed had nothing to do with the topic in hand, followed closely by making a statement such as "you[r] legs need to move further and faster." But then you're not trolling so you wouldn't do that either 1 Link to comment Share on other sites More sharing options...
FamilyBiker Posted August 31, 2013 Report Share Posted August 31, 2013 (edited) force gets levered to torque,gets converted to chain pull,gets converted to torque,finally force again,so it might be possible everyones a bit on the right here. you cant change one thing without the other in a force transmission. if you cut leverage you lose force and rotational revolutions,its really just physics. same ratio,less leverage-more force needed for the same effect. in terms of feeling a shorter crankset would be more "tough" to pedal,meaning you have to put more force in but gaining a bit of pedal travel until you have lost the power or the pedal gets a bad position to use the power or even to land... hope that explains it edit:spelling Edited August 31, 2013 by FamilyBiker Link to comment Share on other sites More sharing options...

Also when you jump the length of time you muscles are contracting is about .2 secounds. And an only accelerate for about the same time Link to comment Share on other sites More sharing options...
