This Black Series by Tune BSA External Bottom Bracket Cups is no longer available although you may find similar or newer versions below:
One of the most impressive and important design benefits of the Black Series chainset is its truly universal fit system. These BSA external bottom bracket cups are designed to fit Black Series & Tune Smart Foot road and MTB cranks.
The cranks integrated 30 mm axle and wider spaced bearings allow BB systems to be configured for practically all current Bottom Bracket standards, while offering increased stiffness, durability and performance.
Each system consists of the highest quality & lowest rolling resistance bearings with additional seals, precision machined external cups or BB inserts and a combination of spacers to achieve perfect chain alignment. Designed and engineered to the highest standards and manufactured with an unrivaled level of accuracy to achieve the highest levels of performance and durability. Hand made in Germany by Tune.
Bicycle bottom brackets connect the cranks to the bike and allow the crank arms to rotate. There are various sizes of bottom bracket shell on the market, so compatibility needs to be checked. The three most common frame bottom bracket shell widths are 68mm (English threaded road and mtb), 70mm (Italian threaded road) and 73mm (British threaded mtb). There are also many axle shapes and styles, from JIS or ISO square tapers through to the round splined axles such as ISIS or Octalink and then there is the new external cup systems which have the axle built into the crank arms. Some frames are now using the new BB30 system which uses bearings pushed directly into the frame and removes the needs for cups to be threaded into the frame.
