I am very pleased with the service and the product from Boca bearings.
I bough a front and back sets of ceramic bearings for a set of Shimano Dura Ace 7800 hubs some six months a go, I install them on my Colnago bicycle and they are running like the wind.
Three weeks a go, I just bought ceramic bearings for my Shimano 7900 hubs, I have them installed in my Specialized Tarmac and after I ride for about 250 miles I can feel a big difference in the way this bicycle is rolling, much faster an lighter.
I like to thank the people at Boca bearings for taking care of me every time I call to ask them questions.
They are friendly and all ways respond fast.
I recommended Boca bearings to some of my friends and some of them already buying their ceramic bearings from them
