175 is easier to spin becuase you have more leverage, 170 will spin the wheel faster...sriracha said:you guys really think 5mm makes a difference in clearance?
the biggest reason to go 170mm vs 175 is that the 170mm is easier to spin, where as the 175 gives you more torque. that's why roadies use 170mm, and that's why most dh racers use 170mm. you can spin easier, therefore increasing your horsepower.
pretty sure you and i are saying the same thing:[email protected] said:175 is easier to spin becuase you have more leverage, 170 will spin the wheel faster...
Think of using a wrench, the longer the wrench, the easier it is to tourque, the shorter the wrench, the faster the bolt spins.. (holding the ends)
I have 175 for DH. I wish they were shorter but not sure 5mm is that big of a difference.gold3nrul3 said:Hey, I ordered a 175mm crank but I am wondering if I should try to get them to change it to the 170mm size before they ship it out? I'm about 5'11" and my old bike had 170mm arms.
I'll be primarily riding freeride/urban/downhill.
Yeah you understand it, just the first time you said 170 is easier to spin than 175... backwards...sriracha said:pretty sure you and i are saying the same thing:
175 = more torque, better for slow speed steep climbs.
170 = more horsepower, better for high speed, spinning the pedals.
where i ride, the 5mm difference in clearance is negligable when you have hub deep rocks.
Its not a big difference, but it is noticable....milhouse said:I have 175 for DH. I wish they were shorter but not sure 5mm is that big of a difference.
