Left crank has become loose and no longer stays on the bike The left crank kept falling off and I've kept on managing to put it back on but finally it wouldn't go. Think the threading is just absolutely kackered. So I ended up taking it to a shop to have a look at and a possible replacement crank. The only one advised to purchase was the Shimano FC-M622 175mm but it is near enough impossible to find and alot of places has discontinued the product. Does anyone know of any other cranks i could purchase instead of this one? Thanks, Tom.
Do you need a 10 speed triple? Any more recent replacement of M622 shoud work (Hollowtech II bottom bracket). FC-M6000 should be absolutely fine. You just need to choose a double or a triple, just choose the appropriate variant (M6000-2 vs. M6000-3).
