Details

BB386 is mostly simply thought of as a 86.5mm wide PF30 bottom bracket shell. The BB386s width places the bearings further apart than both BB30 and PF30. It's designed to match the bearing width of English external bottom brackets. The HSC BB386 bottom bracket features a CNC machined high density delrin shell protecting your frame while pressing your bearings and preventing any creaking. The bearings are HSC's highly durable and fast Si3N4 ceramic bearings with steel races. With the quality of the bottom bracket and its price it makes a high quality replacement or component upgrade saving both weight and lowering resistance over most stock bottom brackets.

Crankset Compatibility

Shimano Hollowtech II

Shimano has not adopted the 30mm spindle of the oversized frame standards and currently doesn't appear that they have any intention of doing so. Good thing companies like HSC are making solutions that are more than just adapters. The Shimano BB386-24 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 GXP

If you have a 24/22mm Sram crank the Sram / Truvativ BB386-24 bottom bracket is for you. Again, this is not an adapter option this is a hybrid ceramic bottom bracket for your PF30 frame.

Ordering

BB386 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.

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.
