Protect the cranks with these 2mm thick printed PU crank boots in black. Nice tight fit to fit Shimano SLX, XT, XTR, & Race Face Atlas. Also tried and tested on GRX, 105 and Ultegra! In reality they will fit almost everything in a similar width and depth to these cranks as they are very flexible.
If you have any custom requests for 3d printed crank boots to fit other cranks please email PT.
