Review: All is good - One year and counting! - I used this BB to install a 165mm Shimano HTII crank on my daughter's Trek 730 with a 68mm BB shell. The install was easy, item is a good quality, and the silver was a nice addition to her bike. It spins freely and has much less resistance than the ancient square taper BB that was originally installed in the bike. It's a reasonably priced piece that looks good too. I'd gladly purchase another if needed for a similar project.
Review: Excellent value for the money - Excellent product at an excellent price. I removed my old square taper crank set and bottom bracket and replaced with this and I now hollow crank set. The fit was perfect, easy to install with torque specs in sight. Looks excellent and gives the bike a wider stance. Don't necessarily have the ability to speak on durability because I haven't owned it long enough yet but it's been on a few hard downhills and has held up extremely well so far
