Description of ZIPP 202 Firecrest Carbon Clincher 6-Loch Disc Rear Wheel - 12x135/142mm / QR - 2017 - Matte Red
Note: Delivery includes the wheel without brake disc only. Other products shown serve solely illustrative purposes and will not be delivered.The ZIPP 202 Firecrest® Carbon Clincher disc-brake rear wheel is all about new technology and new adventures. And a new era for road bikes. This trend-defining wheel is now improved with the durable and versatile 177D rear hub. That innovation means the 202 Firecrest Carbon Clincher disc-brake wheel is now thru-axle compatible.
The 177D hub combines with Zipp's Firecrest technology to offer everything you look for in a disc-brake road wheel. The Zipp 202 Firecrest Carbon Clincher Disc-brake delivers the enhanced modulation and stopping power of disc-braking, whether you stay on the road or venture into less tame territory. At 32mm deep utilizing Zipp's revolutionary Firecrest design, this wheel has the aerodynamic resume of wheels twice its depth yet handles more predictably than a shallow box-section wheel.
In developing the original 202 wheels, Zipp discovered that a wider rim increases lateral stiffness for sprinting and cornering while also providing greater vertical compliance for greater control, comfort and durability. That wider rim profile led ZIPP to develop our Firecrest technology, which revolutionized aerodynamic efficiency and stability for carbon wheels. The proprietary Firecrest rim shape optimizes the aerodynamic profile of the front half and - here's the revolutionary part - the back half of the wheel. Firecrest moves the wheel's center of pressure to be more in line with the steering axis for stability in even the stiffest crosswinds. All of that innovation along with the precision control of disc braking gives you a wheel that's as smooth as it is tough. Firecrest rims have a near-constant width from the outer track to spoke bed to improve aerodynamics and better control airflow. ZIPP uses Computational Fluid Dynamics software analysis to maximize aerodynamics and minimize wind-produced torque.
ABLC and VCLC
You'll also see the rim skin is embossed with lot's of dimples of different diameters in a pattern which forces the airflow to form thinner, turbulent boundary layers. This significantly reduces the interference drag. The turbulent layer also adheres to the wheel skin throughout an increased airflow angle of attack, resulting in significantly lower drag in cross-wind situations, which means you have even more control with the ABLC (Aerodynamic Boundary Layer Control) rim. ABLC increases handling performance by minimizing the low-pressure wake left behind the wheel, allowing for greater tire choice with fewer aerodynamic side effects than seen with other designs. Zipp's exclusive VCLC (Visco-Elastic Constrained Layer Control) technology dramatically reduces rider fatigue, particularly in the hands, arms, neck, and posterior - while greater control of the tire contact patch simultaneously improves cornering grip and minimizes rolling resistance.
About the 177D hub
- bearing preload precision set - that means no pre-load adjustment is needed
- improved bearing protection and sealant
- includes newly designed quick-release skewers with a wider more ergonomic handle to provide more leverage for opening and closing
- Thru-axle compatible - comes with 12x142mm (X-12), 12x135mm thru-axle end caps that can be swapped by hand
- proprietary flange geometry and spoke hole attachment pattern with Sapim® CX-Ray® spokes to optimize torsional and lateral stiffness without sacrificing weight or robustness
- 17mm internal axle
The ZIPP 202 firecrest disc clincher rear wheel features an 11-speed freehub for SRAM/Shimano.
Optionally for those looking for a wider gear range, or tackling especially extreme terrain, a SRAM XD 11-speed driver body for 177D can be easily installed to allow for more cassette options.
