It appears that Cane Creek is abandoning the track wheel market and liquidating its remaining stock at absurdly low prices. I just purchased a new Cane Creek Sprint 50 carbon wheelset for $500, which is 1/3 the MSRP and 1/2 the lowest competitive street price. Compare that with over $2000 street price for a Zipp 404 track wheelset. There are other models also on sale, and this is a great opportunity for anyone who is looking for a great deal on high quality carbon track wheels.
BTW, I am not affiliated with the seller.
