The bottom bracket ensures that your crank rotates smoothly in the frame. In the narrower sense, there are no specific mountain bike bottom brackets, road bike bottom brackets or gravel bottom brackets; however, different manufacturers each set their own priorities with regard to dimensions or use, e.g. with smooth-running or dirt sealing properties. Shimano, SRAM or FSA, for example, offer bottom brackets that encompass a wide range of different uses, sizes and dimensions. Ceramic Speed, Campagnolo or Rotor are more specialised in road bike and gravel bike bottom brackets, while brands such as Hope, Race Face or Reset Racing are particularly popular for (e-)mountain bikes. Our brand filter can help you find exactly what you're looking for. In any case, it’s important that you find the right bicycle bottom bracket for your frame, as there are big differences between many of them. Read further and discover more.
