Bottom Brackets are an essential part of the bicycle that is often overlooked and forgotten, but we saw the BB as another opportunity for performance gains and improved efficiency. For our BB we have developed a seal that achieves a very low level of drag while still retaining excellent protection qualities. Its thinner and low viscosity bearing grease with the correct fill level offers higher durability at high speeds. If you’re running the best crankset on the market, you should have the performance BB to match.

Easton Bottom Brackets have been developed for use in combination with our new Easton EC90 SL crankset. Bottom Brackets are an essential part of the bicycle that is often overlooked and forgotten, but we saw the BB as another opportunity for performance gains and improved efficiency. Typically with any bearing there is a tradeoff between protecting the bearing internals for longevity and bearing seal drag which impact efficiency. For our new BB we have developed a seal that achieves a very low level of seal drag while still retaining excellent protection qualities. Our in-house testing procedure included developing a 24 hour continuous water invasion test, essentially pouring water into the side of the spinning bearings for an entire day continuously. And our new seal proved to have excellent contaminant exclusion. Combining those results with extensive real-world testing, we are confident of the seal's performance and overall BB durability while being impressed by the overall efficiency. We then used a new thinner and low viscosity bearing grease and modified the percentage of grease fill to again find the perfect balance between durability and minimized running friction. We found that a thinner grease, with the correct fill level, was more durable than a thicker grease when spinning at high speed. A thicker lubricant under the centrifugal force would be thrown to the outer bearing race where it would stick and not return to the inner race under lower speeds, leaving it susceptible to increased operating temperatures and higher wear. If you're running the best crankset on the market, you should have the performance BB to match.

TOKEN’s NINJA bottom bracket solves the creaking issues, improves bearing life and adds stiffness to the bottom bracket.They start with Fusion technology; it is a combination of plastic and fibre that cover an alloy bottom bracket shell. The composite material allows it to be precisely machined and fit snugly in the frame so it doesn’t move in the frame and sound like grandma’s clicking and creaking arthritic knees. But plastic and fibre don’t do a good job of supporting bearings; poorly supported bearings can wear prematurely.Token house the bearings in an alloy shell and wrap it with plastic and fibre. This fusion of the three materials provides the bearings a solid platform to sit on and extends their lives. A lot of people would be satisfied with this, but Token went even further by extending the alloy shell so the right and left sides lock together. This locks the frame, cranks and bottom bracket together and provides unparalleled stiffness.The NINJA bottom bracket is can be purchased individually or in a package that includes adapters to fit several different frame and crankset combinations.The NINJA bottom bracket doesn’t just solve the problem of noisy bottom brackets - it actually improves the life of the bottom bracket and makes your bike stiffer. There aren’t many times a replacement part actually improves your bike but put one on your bike and you’ll wonder why you didn’t install a NINJA sooner. Key Features: TBT Premium Bearings .
Axe Cranks use their own specific bottom brackets. Please select either the BSA threaded or one of the PF options, depending on your frame requirement. Please note: The Axe Cranks require the above specific Axe BB's. Other brand 30mm BB cups will not work
