lechatnoir Posted August 27, 2017 Share 175mm Link to comment Share on other sites More sharing options...
Mr lee Posted August 28, 2017 Share 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 Link to comment Share on other sites More sharing options...
Jewbacca Posted August 28, 2017 Share Common but not always correct... But ja. 175mm is standard. Link to comment Share on other sites More sharing options...
Eldron Posted August 28, 2017 Share Cranks used to be: Small frame 170mmMedium frame 172.5mmLarge frame 175mm But all bets seem to be off at the moment... Link to comment Share on other sites More sharing options...
Ispeed_V Posted August 28, 2017 Share 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? Link to comment Share on other sites More sharing options...
BaGearA Posted August 28, 2017 Share Most of the time ( like after 2016 it seems to me ) small bikes come with 170mm and all up from that come with 175mm Link to comment Share on other sites More sharing options...

Any one else have a similar issue and tried the above?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.) Link to comment Share on other sites More sharing options...
