The CCDB is amazing, & I can highly recommend buying from TF Tuned – mine was nigh on perfect. However, I don’t believe it is ‘that’ much better than a Van RC. I ‘had’ to have one and was mildly disappointed when I compared it to my Fox. Having said that, I spent a week trail & DH riding in Morzine this year and this kind of terrain was where it really shone; it was noticeably better.
I can’t recall who said it, but I can believe it when someone said you get 80% of the performance of a CCDB in a tuned for you Van RC, at about 50% of the cost. The prices may have narrowed a bit now but the gist is the same.
As for the weight – I never even noticed it over and abovey RP23 as the suspension felt so much more controlled. Weight is a bit of a none issue to me when I know I could easily shed a stone off my arse!
