Description
ZIPP front wheel 28" 303 Firecrest Carbon Clincher | Tubeless | Center Lock | 12x100 mm thru axle | Force Edition
The optically matching Zipp 303 wheel for the current SRAM Force group. With its dazzling decals, the impeller is perfectly matched to the Force color scheme.
Originally developed to win the spring classics of road pros, the current 303 Firecrest generation is the optimal everyday companion for semi-perfect conditions, bad roads and adverse elements. Under such circumstances, the current 303 is even more efficient and faster than its predecessor. With an inner rim width of 25 millimeters, which is extreme for racing bikes, the Americans are breaking new ground. As found out in Zipp's in-house "The Nest" development center, 28 millimeter wide road tubeless tires with low air pressure roll significantly better than comparable 25 millimeter tires. Especially in poor road conditions, wide all-road tires can demonstrate their advantages in terms of rolling resistance and comfort. Due to the large inner rim width, the rims not only offer wider tires optimal support at low air pressures, they also integrate the tires aerodynamically extremely efficiently into the rim profile. In addition, the hookless design creates an almost seamless transition between tire and rim flanks. The omission of the hooks also makes the rim flanges more robust in the event of punctures and contributes to the significant weight savings compared to the previous versions. The reduced profile height of 40 millimeters makes the 303 even more agile and easy to control even in gusty winds.
Total System Efficiency (TSE)
The 303 Firecrest wheels were developed under the TSE approach. The development goal was to find the best possible impeller design to overcome the speed barriers that exist under realistic driving conditions. In addition to wind resistance, gravity and rolling resistance, this also includes vibration losses in poor road conditions.
ABLC Sawtooth Dimples
The redesigned ABLC Sawtooth dimple design consists of 12 branch points that are timed to match in the rotating impeller. From a frequency of 50 Hz, which corresponds to a speed of 32 km/h, the dimples can demonstrate their aerodynamic advantages and help you to achieve more speed. However, the indentations not only reduce drag, they also ensure very high crosswind stability, especially at larger angles of attack.
Zipp ZR1 hubs
The Zipp ZR1 hubs were developed in two years of development work in Germany. The design of the seals is based on the high-end Cognition hubs and provides more protection and durability with a larger dust cap behind the freewheel body and better seals.
Zip Lifetime Warranty
Zipp gives you a lifetime guarantee on your Zipp wheel if used properly. The warranty also includes racing and damage caused by rider error, as long as the wheel has been used for its intended purpose. The guarantee only applies to the original purchaser and proof of purchase is mandatory!
NOTE: Due to the hookless profile, the Zipp 303 wheels are only suitable with the use of ETRTO-compliant tubeless tires. However, the corresponding tubeless tires can be ridden with tube on the wheels without any problems. You can find an overview of all compatible tires for your Zipp hookless wheelhere .
