Shimano R8000 Chainring Cap

This cap is designed to fit on the inside of the smaller chainring of a Shimano Ultegra R8000 crankset. The cap is to prevent the chain from wedging itself between the small chainring and the BB on frames that have a large BB outer shell such as the Look 795 Series. 

The cap clips on the inner chainring, no mounting hardware or glue required.

Make sure to verify clearance on your particular model. Use Chain Catcher Cap PR1 file to check for fitting and tolerance.
