Details

SRAM created the Press Fit 30 bottom bracket standard as a response to some of the nagging BB30 design problems. Where a BB30 bottom bracket uses a direct fit bearing and circlip design, PF30 houses the bearings in plastic cups which press into a wider 46 mm bottom bracket shell. This updated design allows for simpler installation and noise-free operation without changing crankset designs.

HSC's PF30 bottom bracket represents an affordable, high quality aftermarket option for PF30 framesets. These bottom brackets are CNC machined from high strength delrin plastic and equipped with HSC's hybrid ceramic bearings.

Crankset Compatibility

PF30 bottom brackets are only compatible with frames designed for this standard. Using the three options we currently carry you can use either a Shimano 24mm, Sram / Truvativ 24mm or the 30mm spindle BB30 style crankset this standard was designed around. Feel free to contact us directly for technical questions.

30mm Axle, BB30/PF30 Style Cranks

The BB30 cranks feature a 30mm diameter axle and are much narrower than their 24mm counterparts. This is the original crank that this standard is designed around. The bearing is thinner (Outer Diameter - Inner Diameter) than the 24mm type BBs.

Shimano, 24mm

Shimano has not yet adopted the 30mm spindle of the BB30/PF30 framesets and currently doesn't appear to have any intention of doing so. Luckily companies like HSC are making solutions that are more than just adaptors. The Shimano PF30-24 bottom bracket provides the light weight PF30 interface for Shimano road cranks with all the benefits of HSC's hybrid ceramic bearings. Matching your crank to this standard is easy, if you have any Shimano road crank or 24mm Shimano style crank from another company you will be riding in an hour with this bottom bracket.

Sram / Truvativ GXP

Unlike Shimano Sram has adopted the 30mm PF30/BB30 axle for it's cranks. Most Sram offerings are available in both 30mm and the 24mm standards. If you have the 30mm Sram crank you need the PF30 bottom bracket. If you have a 24mm Sram crank the Sram / Truvativ 24mm bottom bracket is for you. Again, this is not an adaptor option this is a hybrid ceramic bottom bracket for your PF30 frame.

Installation/Assembly

We recommend that PF30 bottom brackets be professionally installed. In the absence of a specific PF30 installation tool, a standard headset press may be used.
