Designed for riders pushing their limits off-road, the CeramicSpeed BB ALPHA BB30 Bottom Bracket for Shimano MTB delivers uncompromising durability and efficiency. Engineered to match BB30 (42mm pressfit, 68mm width) frames with Shimano 24mm cranksets, it ensures precise fitment and maximum power transfer under the harshest riding conditions.
At its core, hardened stainless-steel bearing races are paired with Grade 3 Silicon Nitride ceramic balls, providing CeramicSpeed’s signature ultra-low friction while dramatically increasing resistance to corrosion and wear. The advanced sealing system and precision dust covers boost protection against water, mud, and debris by up to 500%, making it ideal for aggressive trail and endurance riding.
The next-generation BB ALPHA platform features redesigned 7075 aluminum cups and a simplified spacer system, reducing weight by 10% while making installation faster and more intuitive. Handbuilt in Denmark and backed by a lifetime warranty, this is a long-term upgrade built for serious MTB riders.
