Using the Purely Custom XY tool or the Fit Kit Systems Fit Stick on a Purely Custom Fit Bike presents some challenges when attempting to center the tool in the bottom bracket of the variable crank.
Make this a simple task by installing a crank cap!
This machined and anodized metal cap features a 5mm center hole for ease of installation that then doubles as the pin locator for the XY tool and Fit Stick tool. Problem solved.
Sold as single cap – as most people will only measure off one side of a fit bike.
