Strength:

Fits as it should without adapters.

Weakness:

Poor durability

Replaced the Shimano bottom bracket that came with my frame with this SRAM BB for a better fit. The shop that built the bike had used paper thin plastic spacers to shim up the Shimano BB, which quickly melted away as I rode. This caused a wobble and eventually the bearings wore out. It is hard to say which BB performed better because of this installation issue. I was surprised that this GXP bracket's bearings wore out after less than a single season of riding. They now make a clicking noise. I removed the crank and, sure enough, the bearings feel rough when turned by hand. I am a 235 lb. rider, but I do not ride aggressively, and have not exposed this BB to mud, rain, or a lot of dust. I ride 20 miles a week on this bike at the most.

Strength:

None that I am aware of

Weakness:

Wore out in less than 6 months of use

Supplied as original equipment on my 2012 Epic. I have never worn out a BB before in less than 4 years use in my life. The bearings felt stiff after 3 months use. I guess they had gone a bit rusty. They freed off with a backward and forward spin of the cranks. 3 months later there was detectable play, and they needed replacing! When I took the crank out, the left hand inner race was seized on to the shaft and had to be ground off. What a nightmare. I replaced the bearings from a bearing supplier and all working well now. I am unimpressed by BB30. I can only see that it saves money in production, and has no benefit to the owner.
