TOKEN’s 877 external bottom bracket is an extremely high-quality bottom bracket that was designed for use with all Shimano and SRAM GXP cranksets (with additional adapters). The bottom bracket is precision-made for durability and smoothness – and did we mention it also looks pretty fantastic?
We designed this bottom bracket so the bearings rest on the axle of the crankset to provide a straight load to the bearings, which results in a longer life for the bottom bracket. This also allows us to make the 878 with tighter tolerances so it runs smoother with less friction. This bottom bracket is available with our über-smooth TBT bearings or our Premium bearings.
To keep the 878 long-lasting and maintenance-free, we use our patented X-Seals that keep water out of the bearings, which is very important when you ride hard in awful conditions. There are multiple small seals and this reduces the friction while providing a better barrier against moisture and dirt. The bearings themselves are precision manufactured and packed in slick, waterproof grease. To make it even more durable, we use oversized bearings so it is tough enough to use on mountain bikes.
The 878 is an excellent choice for riders who ride hard and want their equipment to be as tough as they are.
Remark: 16-notch bearing cups with an outside diameter of 44mm, torque wrench compatible 3/8" drive.
