Sorry if this has been posted already. Couldn't find anything.

I'm looking to get 162.5mm crank arm or set for my 2005 Giant TCR. It came with 170mm and want to give short crank length a try. Any suggestions where I get find them? Can only find 165mm.

BCD110, 68mmBB, 9-speed compact double.

Thanks.

Please tell us exactly how you decided on 162.5 instead of 165. And before you answer please be aware that though there are lots of formulas to determine crank length, NONE of them are supported by actual data. Crank length is a matter of personal preference, not physiology.

I'm well aware that many of the articles are based on personal testimonial, not based on rigorous scientific study. Having said this, I'm not sure how much anything in cycling is based on rigorous scientific study. It seems that like many of us simply crowd source using sites like RBR.

I asked for 162.5mm as means to get list of places that sell crank arm length less than 165mm. If the cost was reasonable I was going to get few different crank arm to see which I prefer. Judging from the cost, that won't be happening. I'll simply get 165mm to check out if it'll work for me.

Based of vest majority testimonials, "shorter" crank arm doesn't seem to have adverse effect.

That's great, but the OP never said that his decision to "to give short crank length a try" is somehow based on physiology or formulas. It might perfectly well be a matter of trying something else to find their personal preference, exactly as you said it.

Cobb Cycling sells short cranks - 145mm up to 165mm in 5mm increments.

Cobb Cranksets | 145 mm, 155 mm, 160mm, 165mm


My 4' 11" girlfriend bought a set of SRAM Apex cranks from BikeSmith Design. He cuts them down to specific sizes (her's are 145mm). She was having some serious hip impingement issues before getting shorter cranks. She is so much more comfortable on her bike now.

What difference does it make what criteria he is using? He's not asking for us to help him decide what he wants. He's asking where to find the things.

Thanks. That's great.

I'll keep this in mind. I was looking for a cheapest way to try out shorter cranks and found Origin8 in Amazon. http://goo.gl/NrwAZG

I read that using Origin8 had mixed results in shifting performance.

If Origin8 crank arm fits, then I'll play around with different length. If I find that shorter crank length is for me, then I'll spend the money to buy the "proper" crankset.

Thanks for your help.

Speaking from experience, Google isn't very good at giving practical answers to this question

I assume you know that not all cranks bolt on to all bottom brackets? The Origin8 you linked is a square taper. Others linked above you other types of BB adapters. You'll likely need to replace your BB/Adapter to work with the new cranks.

He's complaining that the 162.5 cranks are too expensive compared to the 165. It is therefore reasonable to ask why he feels that 162.5 is a desirable alternative to 165. It goes to the question of "what it's worth."
