Wheels Manufacturing Outboard Bottom Bracket

The bolted outboard bottom brackets from Wheels Manufacturing allow MTB and road cranks with a 24 mm axle to be fitted to frames with road bike BB86 and MTB BB92 bottom bracket shells, with a width of 86–92 mm and a press-fit depth of 41 mm. Also suitable for Trek frames with PressFit 90 bottom bracket shells

BB86 bottom bracket shells:

BB86 bottom bracket shells have a width of 86 mm and a press-fit depth of 41 mm. These bottom brackets are only compatible with road bike cranksets. These bottom brackets are press-fitted.

BB92 bottom bracket shells:

BB92 bottom brackets have a width of 89 to 92 mm and a press-fit depth of 41 mm. These bottom brackets are only compatible with MTB cranksets. Not compatible with MTB cranksets for 83 and 100 mm installation widths. These bottom brackets are press-fit.

Pressfit 90 Trek bottom bracket shells:

The Pressfit 90 bottom bracket shells on Trek frames have a width of 90 mm and a press-fit dimension for the bottom bracket of 41 mm. These bottom brackets are press-fitted. With Wheels or Cane Creek bottom brackets, the bottom bracket cups are screwed together and thus pulled into the bottom bracket shell. This is the significantly more durable method of installation, as the bearings are additionally secured by the bottom bracket cups.

Shimano Hollowtech II crank axle 24 mm / Road - MTB:

The Shimano Hollowtech II crankset system features a solid 24 mm axle. Road bike cranksets have an axle length of 110 mm and MTB cranksets 120 mm. This axle system is also used on FSA Megaexo cranksets and Race Face X-type cranksets. The respective bottom brackets are compatible with one another. The DH Saint and Zee cranks for 83 and 100 mm installation widths have longer axles and will only fit frames with correspondingly wider bottom bracket shells.

Wheels Threaded Outboard:

Unlike other press-fit bottom brackets, the Wheels Manufacturing outboard bearing cups are bolted together. This has the major advantage that the bottom bracket shell sits very securely and absolutely parallel within the frame. This means you can continue to use or salvage frames with slightly worn-out bottom bracket shells. This ensures a long service life for both the bottom bracket and the frame. The bottom bracket cups are made from high-strength aluminium.

Wheels Zero Ceramic Angular Contact Ball Bearings:

The Zero Ceramic Enduro bearings feature high-end Type 3 ceramic balls with stainless steel bearing cups. These ceramic balls are the roundest available for civilian use. The bearing cups are made from pure silicon nitride material with extremely high density and a uniform surface. Furthermore, they are 60 per cent lighter and seven times harder than steel balls. Angular contact ball bearings have raceways in the inner and outer rings that are offset relative to the bearing axis. They are designed for applications that must withstand combined loads, i.e. simultaneous radial and axial loads.
