Light.Easy to install and service.Not expensive.

Bearings not so good.Warranty doesn't cover bearings that aren't so good.

Update to my last review. The non-drive bearing pitted out after only 7 months of mostly dry biking. I figured I'd at least get a year out of it, oh well.I took it over to Supergo but they said the warranty wouldn't cover corroded bearings. But only one was hosed, which their tech at the Santa Monica shop replaced with a better sealed one for $10. He also repacked the other two bearings while he had it apart and didn't charge me any labor, or make me wait, and even showed me how to do it all myself next time. Which I thought was pretty cool.Anyway, the bearings aren't so good, but at least it's serviceable and can even be upgraded. I still think it's a good part, but it needs more maintenance than I expected.

I've had this for some time, but not long enough to say for sure. It's light, but not stupid light. the three bearings are all sealed, so it should be durable, plus the ti spindle keeps it light

poor seals for bearings

I bought this BB a month ago for my brand new Santa Cruz Superlight frame. I liked the three bearing design, relatively low price, and light weight. I had my local bike shop install it when they built up my bike, and since then I've put seven rides and maybe 100 miles on it. It worked fine until last Sunday, when I started to notice a loud sqeak coming from my drivetrain. It sounded like a dry chain, but when I lubed the chain, the noise didn't go away. Then I removed the chain and crank, and spun the spindle with my fingers. No doubt about it, the BB bearings were squeaking like a mouse on crystal meth. Plus there was quite a bit of roughness and resistance on the spindle. Obviously, at least one of the bearings is dry, and probably needs replacement. I have done a couple of creek crossings, and one mildly muddy ride on this BB, and I feel that it should be able to take a lot more abuse before the bearings start to fail. The only thing I can think of is that the seals are inadequate to keep the bearings dry, so any exposure to water will cause the bearings to squeak and fail. This is unacceptable for a mountain bike part. I have sent an e-mail to FSA to ask them if they can warranty the part, or at least send me some new bearings. I'm going to give this part two chilis, with the expectation that FSA will do the right thing and offer some kind of warranty replacement. If they refuse, then I'll be posting an even more negative review in the near future.

Probably premature to review a BB with only a few weeks on it, but it's a pretty impressive part for the money. Installation was easy since it's a direct replacement for Shimano, so if your bike works with Shimano it'll work with one of these. Chainline isn't adjustable but it doesn't need to be. Uses Shimano BB tool which can be found anywhere.It uses 3 standard cartridge bearings. Unlike a UN72/52 once the bearings get scratchy you just replace them for $2 a piece, instead of throwing out the whole part. Or, you can pry the seals off and repack them. UN72's are $20 and these are $60 at Supergo. I only get 6-9 months from a UN72 so this will pay for itself eventually, in the mean time the bike is a lot lighter and it's smooth as can be (so far).BTW, truth in advertising: It says 185g on the box, the scale says 184.Mountain Bike Daily has a review on the Performance version, http://www.mountainbike.com/product/bracket/brackperfti.html

Sub 200 gm. BB. Looks as if it was based on Shimano's UN-72, so easy installation So far, so smooth. Made by FSA, sold under that name by Supergo, also sold by Performance as 'their own' brand.

Light, has bearing lip so an XTR bb mount FD can be used

bearings! they squeal...it's like i'm riding a rocking chair

Don't buy it! buy anything else....those guys are right...the best BB is one you don't have to think about...this one isn't it. It may lighten your bike by a little bit, but I'd take a shimano XT over this. The only good thing i can say is that it has a lip on the drive side so I can mount my Carbon plate XTR front deralliuer on it. I'm going to spend the $20 and make my bike quiet again. Too much noise....

bearings are not the best

very satisfactory overall it did make a significant contribution to shed some weight off my bike which I have upgraded over the years. Three problems: One is that the bearings will creak and will wear out relatively fast and will need adjustments, I use my bike within the boundaries it was designed for and go for long courses in rugged terrain. I do not expect that BB to last more than 2 years. I have now to change it. B- this BB requires care when it is mounted on your bike, very important to not overtighten it. C- the bolt on one side I have never been able to make it tight more than 2 months. eventually it starts creaking bad and needs to be tighten.
Also, NEVER spray water on that BB, it will freeze up after few days. If that happens make sure you check it after 2 days and get it to spin
