Crank length

[brennans]

Hi 

 

What is the most common length crank arm that MTB are sold with ?

 

Thks

[lechatnoir]

175mm

[Mr lee]

175mm

 

I would have said the same but does it not depend on the frame size....  ?

 

I see road bikes have varying sizes depending on the frame size!

 

Oh wait, silly me...I see my wife's medium MTB is also at 175mm

Common but not always correct... But ja. 175mm is standard.

Cranks used to be:

 

Small frame 170mm

Medium frame 172.5mm

Large frame 175mm

 

But all bets seem to be off at the moment...

Slightly off topic. Having one leg slightly shorter than the other (+/- 2cm), would a shorter crank on the longer leg side compensate for the leg discrepancy?

 

Any one else have a similar issue and tried the above?

Most of the time ( like after 2016 it seems to me ) small bikes come with 170mm and all up from that come with 175mm

I have the same problem of 2cm. variance.  Using standard cranks with shoe inserts and a shim.

Works for me.

(Normal shoes are a different kettle of fish.)

Did you fit the shim between the cleat and shoe?

Yes.

[Ispeed_V]

Yes.

Cool thanks. Will give it a try
