Butter b2 RAT Chain Keeper – for bikes with Focus’ RAT rear through axle.
Chain keepers pay their way when it comes time to clean or transport your bike – removing the risk of your chain damaging or chipping the paintwork, allowing you to get your rear wheel and derailleurs properly clean and providing support and structure when transporting your bike.
Now available for bikes with Focus’ RAT rear axle!
“Until now Focus’ ingenious Rapid Axle Technology system was only missing one thing; a butter chain keeper to go with it. In cahoots with Focus, we here at butter developed a simple and elegant solution.
Torture tested by Jeremy Powers and the Boulder Cycle Sport crew, the b2 RAT works like a dream. “
