Chris King ThreadFit Bottom Bracket (24mm spindle)
$170.00 - $240.00
Chris King has been making stainless-steel sealed bearings for 34 years, and never has there been a component that benefited more from their quality than the external bottom bracket. The Chris King bottom bracket is specifically designed for crank systems with outboard bearing cups and is available in the full assortment of colors that only King can do. It all starts with the bearings. King makes their own bearings in-house and the process allows them to place more balls per bearing—24 to be exact . More rolling elements per bearing creates a stronger overall bearing system. This bottom bracket works seamlessly with King's precision injector tool (sold separately) so that flushing new grease into your bottom bracket is a quick and easy operation. Requires a Chris King Conversion Kit for installation.

Praxis Works Conversion Bottom Bracket
$95.00 - $107.00
Best described by the Praxis Works website itself: "Designed to be a proper BB for installing Shimano™ Hollowtech II cranks in either BB30, PF30, or Specialized’s OSBB frames. Our patent pending design keeps the cartridge bearings outboard of the frame right on Shimano™ spec for greater rigidity and free of frame/c-clip tolerance issues that other systems deal with. Simply press in the longer non-drive-cup, then the shorter drive cup threads into it. As the drive cup threads in, our trademark Collet system expands to a precise limit evenly dispersing pressure for a super tight fit. With both cups connected and our collet set exactly to spec, there is no chance the bearings can come out of alignment or wiggle/walk out of the frame. This design also uses a compressible o-ring on the non-drive side cup to compensate for frame shell width discrepancies."
Velo Orange Grand Cru Threadless Bottom Bracket
$95.00
Grand Cru threadless bottom brackets fit most frames, even those with Swiss threading. And they work on frames with damaged BB shells, even if the existing threading is totally stripped. Unlike previous attempts at threadless BBs, this new design is "internally expanding". As the adjustable cup is tightened, the silver sleeve (see photo) is pushed up the tapered alloy cups, expanding and locking in the BB. This differs from older designs, like the Mavic, that pressed in from the outside and would sometimes slip. Installation requires only a traditional-style BB spanner or a pin wrench. The BB shell does not require chamfering or facing; simply slip the BB into the shell and tighten. It is easily removed and existing threads may be reused. Like the other Grand Cru BBs, these have sealed cartridge bearings, so they require no servicing and should have a very long life. Taper is JIS. So far, we have tried these on British, French, and Swiss BB shells and they work perfectly. Customers report that they also work in Raleigh frames with a 71mm wide BB shell. These BB's won't work on mountain bikes, as their standard width (73mm) is too wide for the shell to expand. They do not work on Italian threaded BB shells because those have a wider ID.

Velo Orange Grand Cru French Threaded Bottom Bracket
$60.00 - $80.00
The French thread Grand Cru bottom brackets have oversize sealed bearings. The axles are hollow and made from boron steel. Both cups are aluminum alloy. The bearing are well sealed against dust, mud, and moisture, with four wiper seals at the bearings and two full contact grit shields at the cups. About 258gm in 110mm. JIS taper. Includes axle bolts. Grand Cru BB are available in spindle lengths to fit most cranks.
