I replaced my dad's enduro bottom bracket with this one and it works great. He was able to get 2 seasons of riding with his old one, hopefully this one will last just as long.

One of the cheaper options out there, but keeps you spinning problem free for atleast as long as the slightly more expensive options

Is this compatible with a vintage Cannondale M700 MTB frame? I have a '92 7-speed Cannondale currently fitted with a threaded square tapered BB, 68mm shell. I want to upgrade it to a 10 speed and put a Shimano XT M785 or a XTR M985 crankset on it. Will this Hollowtech BB fit the bill?

An awesome upgrade.

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.

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.

Buttery smooth spinning!

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!

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.
