Wheels Manufacturing PF30 Threaded Zero Ceramic BB

Tired of your Press Fit 30 bottom bracket creaking? Searching for low-friction, high quality, easily maintained ceramic bearings as well? We suspect you are not alone, and we highly recommend you consider the Wheels Manufacturing Threaded Zero Ceramic Bottom Bracket. With two machined aluminum shell that thread together and carry Enduro's Zero Ceramic bearings, you can address both issues at once without compromise.

The internally threaded sleeve halves of the BB shell feature a low profile, oversized 16-notch 48.5mm OD interface, the same used by FSA's MegaEvo system. The Park BBT-29 is the correct tool to use, and you need two to control both halves to achieve the proper fitment. The two machined aluminum cups thread together ensuring the bottom bracket remains stable in the frame, increasing bearing life, and simplifying maintenance. This means no more creaking, smoother operation, longer bearing life, and really quick bearing replacement.

Enduro's Zero Ceramic bearings have (ABEC-5) ceramic balls and steel races. The balls are Grade 3, Silicon Nitride (Si3n4). These are the roundest balls you can buy without a military license. The races are treated with a black oxide coating, which helps prevent rusting in the bearing. The races are then reground to a mirror finish after this treatment. Finally, they are cryogenically treated for strength before assembly. We also use Silicone VV seals, which is the lightest drag seal available on the market. Rheolube special synthetic grease is used in combination with the dual lip and groove seal system to provide smooth operation and keep the bearing from being contaminated.

Wheels Manufacturing specializes in high quality aluminum bike components, made here in Colorado. The company is innovative, smart, and committed to great cycling experiences. With precision made, extremely reliable designs such as this PF30 Threaded Zero Ceramic BB, the company demonstrates why it is a leader in aftermarket upgrades and replacements for discriminating cyclists.
