Wheels Manufacturing PF30 Bottom Bracket

These threaded bottom brackets from Wheels Manufacturing allow MTB and road cranks with 30 mm axles to be fitted into frames with Pressfit 30, Specialized Carbon OSBB and BBRight bottom bracket shells with a width of 61–79 mm and a press-fit depth of 46 mm.

Unlike other press-fit bottom brackets, the Wheels Manufacturing threaded cups are screwed 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.

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 also weigh 60 per cent less and are 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.

BB30 crank axles 30 mm:

BB30 cranks with a continuous 30 mm axle are available from various manufacturers. These crank axles are shorter than those of EVO30 cranks and can therefore also be fitted to frames with bottom bracket shells only 61–79 mm wide.

Pressfit 30 / 68–73 bottom bracket shells:

Pressfit 30 bottom bracket shells have a width of 73 to 68 mm and a press-fit dimension for the bottom bracket of 46 mm. These bottom brackets are pressed into place. With Wheels or Cane Creek bottom brackets, the bearing 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 bearing cups.

BBright bottom bracket shells:

BBright bottom bracket shells have a width of 79 mm and a press-fit dimension for the bottom bracket of 46 mm. These bottom brackets are press-fitted. With Wheels Threaded 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 perfectly secured in the frame by the bottom bracket cups.

Specialized Carbon OSBB bottom bracket shell

The Specialized Carbon OSBB bottom bracket shells have a width of 61 mm and a press-fit dimension for the bottom bracket of 46 mm. Additionally, a spacer set comprising 2 x 2.5 mm and 1 x 1 mm spacers is required, item no. SP0001. These bottom brackets are press-fit. 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.
