I needed to replace an old BB in my 2012 Trek, and this did the job. I find the number of brackets on the market quite mind boggling....so you really need to be careful with ordering the right size. But this was all good, so hit the mark. Sounds really smooth, and pedals noticeably better than the old one.;
