This is a bottom bracket. It's a cheap one but it still works like a bottom bracket does. If you can afford it you'll probably want something a bit more expensive but for the price this thing does what it's supposed to.
Great bottom bracket if you are looking for any BSA frame and you are using a GXP crankset. There are better ones out there but if you need something that is affordable and does the job, this one does the trick.
This is an ok bottom bracket, good for the low price. I don't think it is the best but I haven't had any issues with it. It has been a tiny bit creaky. Overall I would probably buy it again to save money overall in a full bike build.
The SRAM bottom bracket is simple, but it has proven to be reliable and durable. If you want more performance, upgrade to a ceramic Sram BB, or a steel Chris King. Both will offer less drag and better efficiency, but are both much more expensive.
