Excel Sports Boulder is offering Zipp wheels for demo. The charge is $49.95 a day for front wheels and $59.95 a day for rear wheels per day (whether wheels are ridden or not). Most of the demos are done locally through our Boulder, Colorado showroom (303-444-6737), but we can ship if desired. Shipping transit time is not counted toward days used. 100% of daily use fees can be put toward new wheel purchase and new wheels will ship free of any shipping charge including a label to return demo wheels. If new wheels are not purchased, paid return shipping is not provided. This wheel is outfitted a Continental Grand Prix 4000 S tire and an Ultegra 6700 11-28 cassette.
The Firecrest rim shape is the first deep-profile carbon clincher design to offer the superior aerodynamics, ride quality, strength, and handling of a wider rim body at a very light 1557 grams per wheelset - very light for a deep-section clincher. Firecrest employs a complex set of curves to adjust the width of the rim from 25.5mm at the braking track to 27.5mm at the rim's widest point. This shape improves the aerodynamics of the rear wheel as it rotates within the frame. With Firecrest and Zipp's ABLC dimples, the 404 Carbon Clincher far exceeds the aero performance of any other clincher wheelset in its class.
Zipp brake pads are recommended on rims with a carbon breaking surface
