Problem Solvers Self-Extracting Crank Bolts
The Problem Solvers Self-Extracting Crank Bolts take the place of the existing bolts in Shimano/Octalink, Race Face ISIS, and M15-compatible cranksets to let you remove your crankarms with only an 8mm Allen wrench instead of special tools. A 10mm Allen wrench (sold separately) is used to install these fine aluminum self-extractors.
