Technical FAQs Is there anything that can be done with a stripped thread on a crank?
Stripped crank threads are usually caused by incorrect use of the crank extractor tool – i.e. screwing it in squint or not far enough, so use this tool with caution. Cue for a plug for our classes in bicycle maintenance and wheel building. If the thread is stripped, our best advice is to keep on riding the crank till it reaches the end of its useful life, then book the bike into one of our workshops where intelligently-administered brute force will be applied to remove said dead crank prior to its replacement.
