bbinfinitefast Ceramitechℒ️ high-performance bearings with a bushing between the drive and non-drive side achieves the perfect tolerance when preloading. Unlike multi-piece bottom brackets, BBI has created an alternative solution to solve a common problem by using a 1-piece cartridge design. This hub-like cartridge helps increase the overall shell strength to minimize any movement in the cup recesses.

Take a load off.
This bit of kit is designed with a precision drift bushing that gently ties the inner races together, which reduces the chance of overloading bearings, resulting in premature wear.
Cherry on top, right?

So, why is it a big deal?
Bottom bracket creaking and failure are common issues in bikes, especially carbon frames. That said, removing and resolving those issues in a press-fit application is not something anyone should have factored into general maintenance. Over the years, I tested many brackets from square tapered to 24mm, GXP, to arguably the best and worst SRAM DUB, which is what I'm here to talk about!

SRAM's Durable*lol* Unified Bottom Bracket (DUB) is the industry's newest bracket system with some preem crank options, less weight, and a higher watt output. This is a system I believe to be a solid standard, but with some major drawbacks. If you've ever spun a fully assembled crank with the bottom bracket in your hand *without whacking your arm*, then you can put into perspective how much force is being transfered side-to-side. Now imagine over 150lbs of downward pressure through the same motion inside the bottom bracket shell.
This is why I believe SRAM DUB systems fail, is because the flex transfers through the spindle and causes the spacers to rub against the preload ring.
This can change the tolerance and load on the bearings that can cause a loose crankset and/or gradually driving the cups out from the press-fit shell - depending on the frame.

Since the installation back in January 2022, this boosted GX hub hasn't been properly maintained. Yes, you're right, the pawls aren't supposed to come out when greasing, but I needed to further inspect any damages due to being neglected. All tolerances were fine, and Peaty did the job of sealing everything up!
