I decided to try a longer crank arm length for my AirGlide. I'd like to use self-extracting bolts, like the original. Is the Sugino Autex the right/best one? If not, can you recommend one, and where I could purchase them?
The Sugino Autex are fine for self-extracting crank bolts. I personally use the Shimano version and we have these in stock. They run US$12.00 per pair at the time of this writing. We will need to know what cranks you have on your bike to assure you recieve the correct bolts.
