Hi Everyone
Does anyone know of a company that manufactures 172.5cm crank arms?
In case you're wondering what the requirement is, it's to fix a leg length discrepancy.

Shimano, for one.

You're right, but only in the XTR, which is out of my price range.
Sorry, I should have been more specific, I'm looking for something in the Deore LX range.
I also checked out Truvativ and they also have it but only in the high-end products.

My FSA Gossamer crank arms are 172.5mm. Not a MTB crank, but maybe they have other offerings in that size. EDIT - I checked their site and didn't see any in the MTB range.

My guess is they are easy to find on Road cranks, but not MTB.

Yeah, I'm thinking the same. :(

Lots of road cranksets come with 172.5 as a standard option..... maybe look for something with relatively small gears (for a road bike) and look for a CX style crank for more durability?

Another option would be to get the spider/crankarms for a road set with an external BB (more stiffness) and use mountain sized rings on it.....

CX style crank? I'm not familiar, what manufacturer makes that style?
