NOTE: Currently the only cover design I have is to work with chainrings that have a flat mounting surface.  I am attempting to create a mold to work with the taper chainring that Shimano uses as pictured below.  I hope to have this sorted out by the end of April 2020

Flat crank cover design.  If you have  a special need, just let me know and I will try to help you out.

Most Popular Seller for the DIY Installation

Due to all of the various cranksets that are on the market, I am not able to supply a cover that has the crankarm window cut in the cover.


The most popular method we sell is supplying a final cover trimmed to the correct outer diameter as well as a test cutting cover for the crankarm window opening, so two covers sent.  This allow the user to use the supplied test cutting cover to cut the window shape in the test cover and then transfer the shape to the final cover and cut out the window. Below is the crank cover crankarm opening cutting instruction guide to give you an idea of the procedure.
