Shimano didn't forget about the Bottom Bracket when redesigning their Dura-Ace group. Compared to its predecessor, this BB86/BB92 compatible press-fit bottom bracket manages to simultaneously shave weight and boost efficiency, all while maintaining industry leading weather resistance and durability.

These improvements are made possible thanks to slightly smaller bearings that allow for more efficient rolling while furthering weight reduction, and updated seals allow Shimano to drop resistance by a claimed 50%, reducing effort required to pedal with no sacrifice in weather resistance.

The Shimano Dura-Ace BB92-41B Press Fit Bottom Bracket is compatible with BB86 / BB92 bottom bracket shells with 86.5 mm / 91.5 mm widths and 41 mm inner shell diameters. Compatible with the 24 mm spindles found on Hollowtech II cranks.

Works as advertised...

I have two Scott frames and both use this Bottom Bracket. I've been using this model for over a couple years without issues. Seems to hold up well.

Best Budget BB

If you're on a budget build this is probably your best deal. The BB works great. Although I won't need to, I will probably upgrade within the year.

Set and forget.

I upgraded to Ultegra so of course I wanted to switch out the bottom bracket. I honestly can't say whether or not this improves performance over the old version but it certainly does not hinder it. I would have love to buy a Ceramic Speed or Chris King bottom bracket but for the price it's hard to beat this one.

If you are trying to pressfit into a BB86 bottom bracket for a Shimano Hollowtech ROAD cranks, this is the right part

If installed correctly you get the best of what Dura Ace offer, total performance in pedaling. Note well that the left and right bearing cups are not labeled LR, and are weighed the same so if you get them mixed up good luck sleeping at night. The orientation is printed on the inner core sleeve. One must assume that the packaging is vigorously QA from factory to the day you get it in your hands. 41A is the MTB version.

Perfect fit for BB86 frame

The bottom bracket fit perfectly in my BB86 frame. Weighs 54.7 grams on my scale with all the green grease Shimano loaded it up with. Total width about 90mm, diameter that enters frame 41mm, interior diameter 24mm (fits newer Shimano road spindles).
