Rated 2 out of 5 by Needs more attention than any BB I know, works great before it fails. OK, So I got a bike which came with the BB-6000 on a FSA Gossamer Pro Triple crankset. It's not a bad bottom bracket. That being said, it is incapable of staying in good condition. I went through two of these, lasting less than 1000 miles each. Near the end it felt like I had brakes inside my bottom bracket, grating away. The bearing action just cant stay smooth at all. I never paid more than £20 for one of these. O-Rings get torn up really fast and contribute to the bearing issues. All of this being said, I am a massive fan of the Gossamer crankset and I urge people not to forsake it based on the bottom bracket. Even with the BB-6000, it's very stiff. Being just under 100kg I get crazy flex on low and mid range square taper cranksets, and I would never switch back. The other benefit is that FSA cranksets are held together with Allen key bolts, so you can service it on the side of the road very easily, great for touring. Shimano cranksets don't make it so simple. FSA have admitted that all alloy, non-carbon FSA cranksets that use the BB-6000 are 100% compatible with Hollowtech II and Chris King external BBs, Buy the incredible Shimano 5700 105 Bottom Bracket for a 1/4 of the price. It's comparatively invincible. 24 March 2014
Rated 1 out of 5 by Don't last I bought this BB in August and it already needs replacing. I have now used 4 of these in 3 years. Does anyone know a good replacement? 14 December 2013
Rated 1 out of 5 by AVOID This BB came with my bike (Merida Cyclocross). Commuted racingstyle for 6months during winter and it fell apart. Sealing is very poor. Salt and gravel found its way into the bearings and formed a rust colored crunchy paste. Almost impossible to service. Swapped to Chris King - different price - different world. 21 March 2012
Rated 2 out of 5 by surprizingly weak had this on my bike less than 12 months, light use commuting and the lightest of greenlanes and its falling apart. the trek standard issue bottom bracket i had before lasted more than that at half the price! a surprizing let down for fsa 18 December 2009

Answer: 
The BB-6000 is compatible with any 68mm English threaded Shimano Hollowtech II bottom bracket. Like the Ultegra 6700 and the 105 5700 bracket. Get the 105.
