About a year ago I needed a solution to a crank-bottom bracket compatibility issue I was having with my race bike. I knew of adapter system but I was sure the results would be less than perfect. The hassle of installing an adapter plus the creaking and poor performance was not what I wanted for a bike worth more than my car. A friend of mine had been dealing with a similar dilemma and had found the C-bear products to be the ideal solution. But not only could C-Bear offer a solution to this pesky problem, they could improve the performance of all my bearing parts by offering top-quality ceramic bearings. I took the plunge and ordered up bearings for not only my bottom bracket solution but also my race wheels and derailleur pulleys.
Installation was simple and done in a matter of minutes. The results were immediately noticeable with all rolling parts smoothly and incredibly quietly floating along. I was a bit unsure if this kind of performance would last a grueling season of use but after a year my heavily used bottom bracket continues to roll like day 1. I don't get the opportunity to use my race wheels more than about 10 times a year but every time I do I get the pleasure of wheels that seem to want to go faster all the time.
C-Bear full-ceramic derailleur pulleys, if you have not seen the video of how they spin, you should. With the flick of a finger, they spin freely for what seems like minutes. I can tell you they do the same on my bike as well! Thanks C-Bear for keeping me rolling, and rolling and rolling ...
