The most significant [advantage] is a stiffer frame,” says Trek mountain bike product manager John Riley. “Secondarily, BB90/95 offers a lighter overall solution by replacing traditional alloy bearing cups with integrated carbon bearing bores. It also provides a simplified installation process.” Very closely related to Trek’s BB90/BB95 system is the BB86/BB92 standard used by Scott, Giant, Pivot, and many others. In terms of both BBs and cranksets, of course. There are so many (in)compatible standards and how not to get confused or get mismatching equipment? Just follow these simple steps: Pros: Stiffer than BB/PF30, in theory, without impacting other attributes; good crank compatibility, cheaper to manufacture than threaded or BB30The granting of a best price is not combinable with other promotions (e.g. "free articles) from Bike-Discount. Cons: Same as BB90/95 in theory, but in practice there are generally less issues experienced due to the less stringent tolerances In concept, at least, all of the standards we’ve covered are functionally sound. But the realities of relaxing tolerances can create other issues.

In any case they are all interchangeable - you can use BB-RS500 with an R9100 crankset.

Commun Biol 5(1):1181. https://doi.org/10.1038/s42003-022-04102-4 The road standard has an 86.5mm shell width (hence BB86) whilst the mountain bike standard has a 91.5mm shell width. A number of other shell widths may also exist, though they all use the same bearing cups.

Cranksets with 24 mm spindle diameter are not all the same! SRAM and some other manufacturers make spindles that are 24 mm wide at one end, and 22 mm wide on the other, so the correct matching BB needs to be acquired.

Other notes Narrow overall width means longer spindles can be used with appropriate spacers BB30A and BB30-83 Ai Cervélo introduced the new BBright system on the R5ca, and while it offers some sound engineering advantages, other companies have been slow to adopt it Immediate Media More recently, Cannondale announced a variant of BB30 called BB30A. This uses a shell that’s 5mm wider than the original but it’s an asymmetrical layout that only adds those extra millimetres on the non-driveside. According to Cannondale, this allows for wider bearing spacing and better spindle support (which should improve bearing longevity).
