Quality product from Shimano

Nice bottom bracket. I especially like the rubber lip seals on the covers which prevent dirt from entering the bottom bracket housing. Most lower end bottom brackets don't come with these. One recommendation to BOTS is to clearly give the actual dimensions of different sizes on the web page to make it easier to choose. It is always difficult to choose the correct size without trying it out practically. I got a wrong one at first and my chainline was not matching. Then I bought another one after much research and this one fits well.
