First off, I want to thank you for making such a great product. The bearings that I ordered for my WTB LaserDisc Lite hubs wer reasonably priced as compared to a bike specific bearing manufacturer. Once installed, which took all of ten minutes, the bearing initially felt a bit slow, but once I hit the trail for about an hour they loosened right up, they feel so buttery smooth. After they took me to my first MTV race win in over a year, I am never going back. The bearings continue to impress me with their speed and smoothness. And the yellow seal that is lubed for life is a great feature. Overall inexpensive high quality bearing that I would and do recommend to all my riding buds.
