You never know drama of a time trial in a crosswind with a disc wheel until you spend the whole race on the base bar praying you maintain control. Here is a quick fix for the race day in the midst of a squall. The Zipp 404 Carbon Tubular Rear Wheel can be substituted spare the moment, so you can race in the position you have spent hours trying to perfect.
The Zipp 404 Carbon Tubular Rear Wheel is built with 20 spokes, with the 10 drive side arranged in a radial pattern and the 10 non-drive spokes in a cross-two pattern. All spokes are straight-pull Sapim X-Ray with aluminum nipples. The rim width is 22.5mm. The depth is 58mm. The cassette body can come with Campagnolo splines or Shimano/SRAM splines for the appropriate cassettes. The wheel weighs in at 682g. Skewers are not included.
Please Note: Zipp's Tangente Platinum Pro and cork brake pads are designed specifically for use with their carbon tubulars. Use of brake pads other than these is highly recommended against and will void the wheel warranty.
