T47 Outboard Threaded Bottom Bracket

We realize you're probably sick of hearing about the latest and greatest advancements in bottom brackets, seeing new standards are introduced practically every year. However, you'd be foolish to dismiss the recently adopted T47 threaded bottom bracket as just another standard imposed to relegate your current bottom bracket as useless. In fact, T47 presents an impressive array of benefits to the the custom frame builder and smaller bike company seeking a creak-free, precisely aligned shell boasting the extra stiffness of oversized press fit shells. This particular Wheels Mfg T47 Outboard Threaded Bottom Bracket works with frames using the T47 bottom bracket standard and accommodates a number of road and mountain bike cranksets.

Wheels Mfg offers 30-millimeter, SRAM GXP 22/24-millimeter, and Shimano 24-millimeter versions that cater to a number of different cranksets on the market. Each T47 bottom bracket is compatible with T47 bottom bracket shell widths of 68 to 100 millimeters. This particular version uses machined aluminum cups that thread together, complete with outboard bearings for smooth operation and easy replacement once worn out. Additionally, it includes a sleeve that keeps out dirt and grime, plus keeps your cables from rubbing on the crank spindle.

Quality Unit Before Issues

I've put it through the wringer

*Latent Edit - CC Gearhead took care of me and I have been riding for several months. I do feel like I need to pull and grease this unit more than my other bikes.

Great Quality!

Got this as a replacement for my Praxis bottom bracket that came on my Ibis Hakka MX as I was changing out the cranks. At first when I put my Hakka together with the Praxis I thought the threads were not chased but after putting on the Wheels MFG it went on smooth so it seems like the Praxis had some thread issues. Have put on a few miles since getting it and the bottom bracket is still spinning smoothly.


Good morning CC - would the T47 30mm version work with the Easton EC90 crankset? Do I need extra spacers? Thanks
