FSA QR-20 Self Extracting Crank Bolt Assembly - M17 Bolt with M27 Cap Info
The FSA QR-20 Self Extracting Crank Bolt Assembly — M17 Bolt with M27 Cap is a purpose-built replacement bolt assembly designed to simplify crank installation and removal on compatible FSA cranksets. The self-extracting design eliminates the need for a separate crank puller, making roadside adjustments or workshop maintenance considerably more straightforward.
Sized with an M17 bolt and M27 extraction cap, this assembly is engineered to FSA's QR-20 interface specifications. If you're replacing a worn or damaged bolt on an existing FSA crank, using the correct spec hardware matters — mismatched threading or cap sizing can damage the spindle or crank arm over time.
