We care about the details and that is why we hand assemble the 877 Bottom Bracket. The careful assembly means we can check to ensure that only the most precisely machined bearings and smooth bearing races are packed and sent out. Whether you choose the ceramic TBT bearings or our Premium bearings, they fit precisely in the forged and CNC machines 6061 alloy cups. To make sure they stay in place, we coat the threads with Loctite. All this technology isn’t hidden away in a boring package; the 877 is available in a range of colours.
