Very Nice indeed. What are the differences between the two top end groupsets?
well now your asking
The suntour shifters are very nice and clicky, along with a neat slim clamp design. The hubs use sealed bearings and have grease ports, so should last forever. splines on the XC pro freewheel are different to shimano so you have to use Suntour cassette, these are hard to get. The front mech looks sleek and well made along with the fact you can split the cage from the tube clamp, but I can see a lot of play in the area developing as the bush wears out.
In short I think the Shimano stuff is tuff as boots and would take a harsh winter pounding without reliability issue, and the Suntour maybe not?
I heard that shifting and reliability problems earned the SUNTOUR stuff a bad name on the racing curcuit BITD, but it was said to be good at first.
