Product Description

Our premier offering is an evolution of a tool that’s resided in our toolboxes for many years. butter's b1 is a premium quality chain keeper for bikes with a quick release dropout.

Our mission with the b1 is to enhance your experience when it comes to cleaning or storing your bike by refining a pro mechanic staple into an elegant and highly functional accessory. We've taken a utilitarian tool and made it better in materials, feel, weight, and overall awesomeness. The design of the b1 performs solidly and its outstanding build quality ensures that it will never wear out or break. Machined from top-shelf materials such as billet aluminum, Delrin, and stainless steel, this chain keeper is virtually bomb-proof.

The b1 is hand assembled in Boulder, Colorado.
