Which is better 170mm or 175mm cranks?
A 175mm crank is likely to be a much smaller percentage of a very tall person’s leg length than a 170mm crank is for a comparatively shorter person. Again, though, each person’s individual limb proportions will be different, so it’s hard to make generalisations.
How much difference does crank length make?
‘The research evidence is clear: crank length makes no difference to power on the road – track is slightly different – unless you go as short as 80mm or as long as 320mm. And as a bike fitter and physiotherapist, I’ve never had a reason to go bigger.
Are 170mm cranks good?
However, the shorter (170mm) cranks were quicker to accelerate up to maximal power. This could have benefits for all the racers out there, be it Enduro, Downhill or XC, as being able to accelerate those pedals faster could have you sprinting out of corners, closing gaps, or starting quicker than before.
Are longer cranks better for climbing?
If you’re having problems with your lowest gear, stick with longer cranks. They reduce force at the same gear ratio. Shorter cranks allow you to use a lower gear at the same foot speed… but if you don’t have a lower gear, you’re stuck.
What is the difference between 165mm and 170mm crank?
The difference in these 165mm and 170mm cranks is reportedly just about 3% and can be overlooked by some but not all. This similarity in length makes the shorter cranks less priority for manufacturers compared to the longer cranks since there’s a higher population demanding the longer crank arms.
Who should use 175mm cranks?
If the inseam X 0.216 is applied, then anyone with an inseam of more than 810mm (which is not a long inseam) would need to use a crank of over 175mm.
Is 160mm crank too short?
5 Answers. Show activity on this post. 160mm crank is abnormally short. This doesn’t mean that you shouldn’t but as Axemasta mentions, you should have a bike fit before deciding what crank arm length you should have.
Should I use 165mm cranks?
Trying to decide between a 165 and 170mm crank is a waste of time as there is too small of a difference to matter. An athlete should pick the length that allows them to most comfortably apply force to the pedals without restriction.
What crank length do pro cyclists use?
Most cranks commercially available range from 165 to 175 mm. This 1 cm span equals about 1/3 inch yet is supposed to fit riders from under 5 feet tall to well over 6 feet. Very tall cyclists can buy 180-mm cranks from a few companies, but that’s generally the upper limit without an investment in custom production.
