Butter's B2 chain keeper makes cleaning your chain a snap. Remove the rear wheel, install the B2, and rotate the cranks as usual. The Butter B2 keeps the chain in place and running free so you can easily clean and lubricate it.
The B2 is also great for travel when you are transporting your bike with the wheels off.
- Sturdy aluminum, stainless steel, and delrin construction will never wear out or break
- Manufactured and assembled in Boulder, Colorado
COMPATIBILITY
Fits just about ever 12 x 142mm thru-axle bike out there, including road, MTB, cyclocross, and gravel; with the exception of non-standard axle variants like the Focus RAT axle.
It's simple. It's smooth. It lasts. It protects. It's butter.
