Product Description

Along with BB86, this Shimano BB92 Bottom Bracket is part of the new pressfit standard. It offers frame designers a little more room for new designs in seat/down tubes and rear suspension layout. Where a typical mountain bike has a 68 or 73mm bottom bracket shell width, a BB92 equipped bike has a shell that measures 91.5mm wide. A BB92 shell lacks internal threads and has a 41mm inside diameter.This Shimano BB92 Bottom Bracket is made to press right into your bike. It will mate your Shimano HollowTech crankset to any frame equipped with a BB92 bottom bracket shell. This bottom bracket comes with two steel cartridge bearings pressed into composite cups. The cups increase the outside diameter of the assembly to 41mm to match the i.d. of the frame's bottom bracket shell. There is a 1.75mm thick outer lip that provides a positive stop for the cups when you press them into place. Shimano includes their standard plastic o-ringed inner sleeve to protect against water damage should it find a way inside your frame. It uses black plastic dust shields that snap into the inner race of each bearing.*Note: BB91 and BB92 are identical bottom brackets.

Ripley: Why BB92 instead of BB30?

I'm getting my build together and I'm looking at crank weights.... almost all the cranks are between 75 and 100 grams heavier in the BB92. Question: When typical is to go larger diameter, thinner, lighter, why BB92 (25mm?) on the Ripley? :confused: I'm going to dislike adding 100 grams to an e ... Read More »

5.7C BB92 build question

Started my build last night on my 5.7c. The frame ame from the factory with the BB92 already pressed in.
