Wheels Manufacturing PressFit 86/92 Bottom Bracket w/Ceramic Bearings - Shimano Compatible - red

First impressions are that it's well made and perfectly manufactured. The bearings are nice and smoothed and it has o-ring on ether ends to seal against water an durt. I don't know about longivaty. But it sure looks a whole lot better than the shimano disposable one. I feel confident that I made a good investment. And for the pirice of 85 bucks I don't think that I will find another ceramic bearing anything let alone a bb.

This BB started out very well and appears to be nicely put together. However, after riding it for less than two months, the bearings (ceramic) are completely worn out on one side. I'm hoping this in a manufacturing defect but my perspective after this limited usage is that it is not worth the money. I'm hoping I'm wrong.

Only lasted just over a year. The cheap standard bearings that came on the bike originally lasted 2 years. Very poor quality.

Perfect for my Wilier Cento10Air. Very smooth and east install with their Press Fit Tool.

nice fully sealed design (important in rainy Seattle), great upgrade from OEM bottom bracket and for ceramic bearings the price can't be beat
