Can anyone tell me how to remove the self-extracting bolts from shimano octalink era cranks? the type with the two small holeseither side of the bolt. What kind of tool is required?
mmm ta, I tried my pin spanner (didn't know it was called that until now) that I bought to fit a royce BB but the pins are too big. I can't find any on ebay with pins less than 4mm, except a £60 one :?
