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 5800 105 and 6800 Ultegra! In reality they will fit almost everything in a similar width and depth to these cranks as they are very flexible.
For the thin versions that clear pedal based power meters, please check the other product listings.
