Bottom Bracket Wheels Manufacturing

These threaded bottom brackets from Wheels Manufacturing allow MTB and road cranks with 30 mm axles to be fitted to frames with BB386Evo and BB3921Evo bottom bracket shells, which have a width of 86–92 mm and a press-fit depth of 46 mm. These bottom brackets are compatible with cranksets featuring a 30 mm axle system, such as FSA BB386, Race Face Chinch 30, Rotor 30 and Sram BB386Evo cranksets. These cranksets have longer axles than BB30 cranksets, from 103 mm upwards. BB30 cranksets cannot be fitted to these bottom brackets.

Unlike other press-fit bottom brackets, the Wheels Manufacturing cup sets are bolted together. This has the major advantage that the bottom bracket shell sits very securely and absolutely parallel within the frame. This ensures a long service life for the bottom bracket. The bottom bracket cups are made from high-strength aluminium. For optimum durability, Wheels MFG manufactures its own bottom bracket cups for each bottom bracket shell, with the correct offset, even if the press-fit dimension is the same as for 386EVO, Pressfit 30 and BBright bottom brackets. This ensures that the bearings are positioned as far outwards as possible and the crank axle is supported in the best possible way. Other manufacturers use spacers for the different installation widths, which is not quite as ideal.

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. They are also 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 bearings that must withstand combined loads, i.e. simultaneous radial and axial loads.

30 mm crank axles:

Cranks with a continuous 30 mm axle are offered by various manufacturers, e.g. the Cane Creek eeWings, FSA BB386EVO, e*thriteen, Race Face Chinch 30, Sram EVO 86 and Rotor 30. These crank axles are longer than those of BB30 cranks and can therefore also be fitted to frames with bottom bracket shells 79–92 mm wide

BB386EVO bottom bracket shells:

The 386EVO bottom bracket shells have a width of 86.5 mm and a press-fit dimension for the bottom bracket of 46 mm. These bottom brackets are press-fitted. With Wheels or Cane Creek bottom brackets, the bearing sleeves are screwed together and thus pulled into the bottom bracket shell. This is the significantly more durable method of assembly, as the bearings are additionally secured by the bearing sleeve.

BB392EVO bottom bracket shell:

The 392EVO bottom bracket shells have a width of 92 mm and a press-fit dimension for the bottom bracket of 46 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 assembly method, as the bearings are additionally secured by the bottom bracket cup.
