Bottom Brackets – Where Power Meets the Road
A bicycle is only as good as its smallest components – and the bottom bracket is definitely one of them. Hidden in the bottom bracket shell of your frame, it performs its job inconspicuously, but without a functioning bottom bracket? No forward motion. This is where everything revolves – quite literally. want read more.

Why the Bottom Bracket Is Underestimated (But Shouldn't Be)
Let's be honest: Who thinks about the bottom bracket first when buying a bike? Probably very few. Yet this inconspicuous component is the crucial connection point between crank and frame. It ensures that your pedaling power is efficiently transferred to the chain and thus to the rear wheel. Without a low-friction, precisely working bottom bracket, energy is wasted and the riding experience suffers noticeably.
A high-quality bottom bracket makes the difference between effortless gliding and tough grinding – especially on longer tours or challenging trails, you'll notice this immediately.
From BSA to BB30: Standards You Should Know
The world of bottom brackets is more diverse than one might initially think. BSA, ITA, BB30, PF30, BB86 – sounds like a secret code? It's not. These standards describe how the bottom bracket fits into your frame and which crank you can use. The classic is the BSA standard with its thread – robust, proven, and widely distributed. Press-fit systems like BB30 or PF30 rely on a stiffer connection and are mainly found on modern road bikes and mountain bikes.
The good news: We have the right solution for every standard in our range.
Adapters – When Two Standards Want to Meet
You've found an awesome SRAM DUB crank, but your bottom bracket is designed for 30mm spindles? No problem. That's exactly what bottom bracket adapters are for. These clever conversion kits create compatibility between different crank spindle diameters and bottom brackets – without having to replace the entire system.
Particularly practical when you own high-quality components from Hope or Chris King and don't want to give up on modern crank standards. Adapters give you maximum flexibility in component choice while protecting your budget.
Spare Parts: Maintenance Instead of Replacement
A bottom bracket is not a disposable product. With the right spare parts – new bearings, fresh seals, matching spacers – you can get years more out of your system. Especially with premium bottom brackets, investing in original spare parts pays off. Regular maintenance prevents expensive consequential damage and keeps your bike running smoothly.
By the way: A thin layer of grease on the seals works wonders against moisture penetration. Small measure, big effect.
When Should You Keep an Eye on Your Bottom Bracket?
At the latest when it grinds, creaks, or feels stiff when pedaling, action is required. Lateral play in the crank is also a clear warning signal. Depending on the application – road bike, MTB, or e-bike – maintenance intervals vary. Mountain bikers who regularly plow through mud and muck should check more often than asphalt cruisers.
