Super Upgrade - Great Improvement
This is a great solution to replace the terrible press fit bottom brackets - which are inherently prone to making lots of snapping, clicking and popping sounds. This BB is very smooth and quiet....simple and easy to install properly. I installed it on a 2014 Giant Trance - an amazing upgrade compared to the OEM press fit BB trash.

Came with spacers but no instructions
My trek has bb91 aka bb92 bottom bracket with press fit bearings. I had upgraded to an enduro bb with replaceable bearings but that's usually not my issue, it's the creaking of the press fit shell. So this looks interesting in design/concept, it's more of a 'pull fit' than a press fit. There's a red endcap included with this that just falls out when I push the crank through, not sure if that's needed somehow. There are 2 spacers and a wavy washer included which mine doesn't have, but probably needs, on the drive side.Ther are 2 'mushroom cap' cover/liners which covers the outer bearings from dust and also lines the inner bearing surface which the spindle rides on. I don't like this, in a few years this will disintegrate and I will have to trash this whole unit.

Might be good.
I have to agree with Peter The edge is very thin for the tool. If you don't have the right tool it's going to be a pain in the butt or you're going to damage your frame or the bracket.I like the original on my bike which had a 24-in bearing on the drive side in a 22-in bearing on the non-drive side this one is 24 and 24. It includes a coupling that reduces 24 to 22. It doesn't seem quite as snug as it should. I'll check back in when I put some miles on it.

impossible to remove
Worked great, easy to install. I just snugged it up being careful not to over tighten. However the teeth on the outer edges are very very soft. I srtipped the drive side like it was made from butter when trying to remove it. I took it to my bike shop. These guys know their stuff. They stripped the other side instantly and with the proper shop grade tool. Now I have a 7000.00 bike with a stripped bottom bracket stuck in it. Im going to have to cut it out. Do not buy this product. Its a serious headache upon removal. Super frustrating

Buy extra spacers.
Make sure you have extra spacers. I had to add some. I have about 100 miles on it. Seems to be working great.

Good BB
I was skeptical because I've mainly ever used Shimano or FSA, At first it seemed flimsy, but once on the bike, its perfect. It does exactly what it needs to do. Good BB and will probably be going on my next build.
