I just tried to remove a pair of cranks, the first time for this new bb/crankset setup, and the tip of the puller was too small and just slid into the hole that goes through the bb (isis). Is there a specific crankarm puller for isis drive bb's? Right now I am using a Wrench Force puller, the one with the triangular red plactic handle looking thing. On another note, does moisture and or cold weather ever make a bb squeak? It only does it on one part of a full pedal rotation.
