I had been considering upgrading my bottom bracket for a few months so when I saw thing on sale I couldn't resist. My only regret is that I didn't upgrade sooner, as this was a massive difference from my stock bottom bracket.
This is my 3rd Ceramic Speed Bottom Bracket (2 for road bikes) and all is working great. The Bottom bracket is fitted to my Enve MOG and had no issues with it when racing BWR AZ a few weeks ago.
replaced stock shimano for this one and instantly feel the smoothness on the upstroke. Get the park tool bbt tool though, T47 are impossible for engagement
