DURA-ACE
The Shimano DURA-ACE SM-BB92-41B is a press-fit bottom bracket for road frames built around the 86.5 mm BB86 standard with a 41 mm shell I.D. If you're running a Shimano HOLLOWTECH II road crank, this is the clean, lightweight option that gives you the right fit without overcomplicating the build.
What stands out here is the focus on low weight and smooth running. Shimano uses small ball bearings to keep weight down, and the advanced seal construction is designed to help the bearings spin smoothly while keeping contamination out. For a customer choosing between budget and premium Shimano press-fit units, this sits at the lighter end while still being a practical everyday road choice.
It also makes sense if you want to stay with a standard press-fit cup system rather than moving to a heavier thread-together conversion bottom bracket. Installation needs the correct press-fit tools and a frame shell that is clean and in good condition, so it's best suited to riders who want a proper factory-style BB86 setup for a road race, endurance or performance bike.
Ideal for the road rider rebuilding or replacing a BB86 / PF41 bottom bracket on a bike with a 24 mm Shimano HOLLOWTECH II crankset.
Built for BB86 road frames
Designed for 86.5 mm press-fit shells with a 41 mm inner diameter, making it the right match for BB86 road frame standards.
HOLLOWTECH II compatibility
Suited to 24 mm Shimano HOLLOWTECH II road cranksets, so it fits neatly into Shimano-based road builds.
Lightweight DURA-ACE construction
At 54 g, it keeps rotating weight low and suits performance-focused road bikes.
Small ball bearing design
Uses small ball bearings to reduce weight while keeping the bottom bracket compact and efficient.
Advanced seal construction
The sealing is designed to support smoother rotation and help keep grit and moisture away from the bearings.
Factory-style press-fit solution
A simple, standard Shimano cup-style setup for riders who want the original-style BB86 fit rather than a conversion system.
Shimano service support
Supported by Shimano dealer documentation and dedicated install and removal tools for straightforward workshop servicing.
