An awesome upgrade.

  • Familiarity: I've used it several times

The Bottom Bracket that keeps on spinning. After wearing out an older Shimano bottom bracket, the MT800 seemed like a logical upgrade. The smaller cups do require a special adaptor to install (this is included so installation with a regular BB tool is easy). So far, after nearly a month of hard riding and no maintenance, the BB still spins perfectly.

Super Smooth

  • Familiarity: I've put it through the wringer

If you are looking for a threaded bottom bracket to pair up with your Shimano crank this is it. Super reliable, smooth, and reasonably priced.

Great Bottom Bracket

  • Familiarity: I've put it through the wringer

I would highly recommend this bottom bracket. Compatibility questions? Hit me up at adickinson@backcountry.com

I have a 2008 OEM Shimano Hollowtech crank 9spd, 73mm BB... will this fit?

Will this Bottom Bracket fit my 2016 S-Work Camber 650b?

Hi Aaron, no this is not compatible with your bike. I will shoot you an email with a bit more info.

Hi Aaron

This bracket will fit my Felt nine 6 2015 with 73mm shell , and also want to install cranks Shimano Deore M615 10 Speed Double Chainset?

Thanks a lor for you pro advise

Buttery smooth spinning!

  • Familiarity: I've used it once or twice and have initial impressions

Got this BB to replace my old, not quite worn out but definitely needing some help, BB. The old one was also a Shimano, came on the bike lasted about a year or so through some gnarly riding, and since Shimano has always done well for me I selected this one as the successor. I honestly didn't expect much above and beyond the old one, figured this one was just a new version of the one I had, but man this BB is nice and smooth! Installed with 0 problems and works great with my M8000 crank set. For the price, you can't beat it!

Replaced a SRAM Howitzer

The BB on my necro Pug was frozen. I tried to clean it up, keep it spinning, but my efforts were largely pointless.

Yes, Shimano makes a sweet sealed BB. I've ridden it a bit since I installed this. I'm not using the plastic insert since the Q on my bike is 100 mm, but otherwise, it spins freely. I've ridden in very dusty conditions as well as on briny beaches. The sealed cups and bearings are boss. Seriously, if you ride a fat-bike in anything, but the most benign conditions you need to step up the BB to sealed.

Perfect

  • Familiarity: I've put it through the wringer

Simple, quality and easy to install. No sense in changing a good thing!

Threaded rocks

  • Familiarity: I've put it through the wringer

Durable and it won't creak. Threaded BB's rock Works with all shimano cranks.
