Chain Reaction Cycles currently has a clearence on Vitus frames
with some pretty good discounts (over 80% in some cases).
Most of their frames are alloy, but both the Zenium VR and (I think) the Zenium R‘s have carbon seat stays (which is one of the more effective ways to get the vibration absorbion of carbon).

It’s the prices that make these worth looking at though. The Zenium R
is priced from $149 (+$23 shipping to the US), and the Zenium VR is from $170. Those prices are pretty competitive with anything you’ll find on ebay, and in this case you get a well known reseller backing it up.

I really like the look of the Zenium VR frameset, too.
