sammyboy2011 Posted March 15, 2011 Report Share Posted March 15, 2011 hi guys, i am currently running 170mm tensile cranks on my 20'' onza, but i am looking to uprade! i think i am goin to order some try-all isis cranks from tarty this week but dont know if i should stay with the 170mm or go for the 175mm cranks. does the extra 10mm make much of a difference, if so what can i expect? many thanks sam Quote Link to comment Share on other sites More sharing options...
Miles Mallinson Posted March 15, 2011 Report Share Posted March 15, 2011 Mainly mods run 160-165mm but you can still use 170-175mm you will feel a very slight difference in the gearing it will be lighter because of the leverage in the slightly longer cranks, but stay with 170mm if you like your gear the the moment Quote Link to comment Share on other sites More sharing options...
