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 grease will not leak out and dirt will not get in, the bearings do not need to re-grease or service. Servicing or opening the seals will damage the seals. Bearings for all brands and for bottom brackets and hubs will get damaged if exposed to degreaser, petrol, isopropyl alcohol, solvents, thinner, wd-40. DO NOT degrease or spray solvents on your chain while it is still attached to your bike, the solvents and degreaser will seep into your bottom bracket and wheelset hubs and degrease the bearings shortening the lifespan.
