This is Wheels Manufacturing's original BB86/92 bottom bracket and is a significant upgrade to OEM BB86 bottom brackets or the perfect first step when starting a custom build. Two machined aluminum cups offer increased durability and bearing life, while keeping a simple press together method for installation and maintenance. The cups are far more resilient than the typical plastic offerings and do a better job of protecting the bearings from excessive press from an undersized bottom bracket shell. Rubber o-rings, housed in machined recesses on the cups, prevent water or other contaminants from entering your frame.
The bearings are ABEC-3 rated and feature high precision Grade 10 chromium steel balls that are within 10/1,000,000 inch round, twice as round as the industry standard. Highly polished chromium alloy races ensure smooth spinning and quiet operation. Installation is pretty straightforward provided you have the appropriate bearing press. This particular bottom bracket is engineered for SRAM/Truvativ GXP standard cranks which feature a 24 to 22mm stepped spindle. All necessary spacers and shims are included.

- Q & A
- Familiarity: I've used it once or twice and have initial impressions
I opted for this BB over a standard Sram one since it feels like it's way higher quality. I can't comment on the durability in the field, but just looking at the material used I know this will install easier, creak less, and provide a longer service life.
Very high quality, durable, no creaks
- Familiarity: I've put it through the wringer
I used this BB on the recommend of Backcountry for my custom Yeti SB5c Turq build. It is machined and manufactured to a very high quality. I've ridden the bike hard and I'm not a small guy. I haven't had a single creak or issue out of the BB. Wheels Mfg is a top quality company. Worth the $.
