Review on Upgraded Press Fit 30 to Outboard Bottom Bracket with Superior ABEC 3 Bearings for Enhanced Performance by Wayne Ohlrogge

Seems to be a really well made item. However, this did not go so well with my application. When fitted to my Specialized Stumpjumper, it is too wide for my Shimano Zee cranks to engage properly. I ended up removing the boot from the drive side and all went well. I'm sure this will reduce bearing life. If I didn't have time I would return it, but I'm taking a risk with this configuration. Hope it lasts a while.
