I have the whole group on both of my bigger bikes. the hubs are great, light and easy to service. although the new 07 versions are lighter. the RD and the shifter (rapid fire) are just awesome. I have bashed that RD off so many rocks and it still shifts with out question. the outboard mounted RH shifter is very user friendly as well. The cranks are beyond belief. they are by far the stiffest, toughest, awesomest cranks I've ever used. And the Brakes are just as good. I cant complain about any of the saint parts. I have been so completely happy with mine so far. I even put the saint brakes on my XC bike.
