Product Description

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.

Bottom Brackets Guide

What is a bottom bracket?

A bottom bracket is the bearings that the crank axle passes through, keeping the cranks turning smoothly.

Who needs a bottom bracket?

Every bike has a bottom bracket, so if your bike is creaking or feels stiff or notchy as you turn the pedals, your bottom bracket might be worn out and need replacing.

What are the choices?

It’s not so much a choice as a matter of compatibility. You need to establish whether your bottom bracket is press-fit or threaded and what size. Then you need to make sure it is compatible with your crankset. If it’s worn out, replacing like for like is often the easiest thing to do.

What should I buy with it?

You need some specialist tools both to fit and remove bottom brackets and to remove the cranks to get at it.

Anything else?

If you’re fitting a bottom bracket into a brand new frame, your frame will need some preparation first. Bottom bracket shell facing tools can be very costly, so you might need to bring it into a bike workshop to get this done.
