Using the Purely Custom XY tool or the Fit Kit Systems Fit Stick on an older Fit Bike presents some challenges when attempting to center the tool in the bottom bracket of the variable crank – if there is no recess to accept the BB pin.
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.
