So I just bought a new set of CSC wheels - Disc, 45mm / 28mm wide with their OEM DT Like hub. The wheels came dead true and evenly tensioned. I took the hub apart and it was well greased. Shipping was 3 weeks to Chicago.
This would be my fourth experience with CSC over the last 5 years. I have had a very good experience with them so far. I'm sad to see you have had issues. I do agree there is little technical support from them But, I have not needed any.
My riding buddy has had his 50mm CSC Disc wheelset w/ novatec hubs for 3 years (8k miles a year on mixed, flat terrain -160lb rider) and his wheels have needed zero maintenance. I serviced them once a year for him and the original bearings are still in good shape and the wheels have needed zero truing. There is a little cassette bite on the freehub but that is really a novatec issue and not a CSC thing.
I rode a borrowed pair a few years back and my brother has a 2 yr old set as well with the same result.
Just my honest feedback and experience. Hope that helps anyone out there giving them a look. I'm interested to see how the OEM hub performs long term. Initial look appears to be good quality. I am prepared for the bearings to be rather short lived (they are un branded black seal non contact bearings - smooth out of the box) but I can replace them easily if they get gritty.
