Zipp 404 Clincher Wheelset (Pair) 2008

* All our Zipp Wheels are factory built in the USA.  *

The  Zipp 404 clincher wheelset is the our most popular wheelset .The 404 is crafted especially for people who demand the ultimate performance this side of disc wheels without trading the convenience of clincher tires, and who expect the kind of all-day comfort that makes it easy to train and race on the same wheels. The 700c 404 clincher sports an aerodynamic dimpled surface. And you thought that they couldnt get any faster.

The reduction in vibration frequency provided by Zipp VCLC technology shows that while the 404 clincher rim is nearly half the weight and double the lateral stiffness of an all aluminum box style rim, the 404 clincher rim has a LOWER natural frequency when subjected to vertical inputs. This rim transfers 10.9% less impact force to the rider than the standard aluminum traditional alloy rim and diminishes subsequent remaining vibrations nearly 30% faster. The result is more comfort and improved handling through improved ground contact. We understand that after six hours in the saddle every road seam can feel like the world's largest pothole, so no stone was left unturned as we sought to design the first high frequency suspension system for your road or TT bike.

Patent pending ABLC dimpling technology applied to the surface of the rim (700c only) allows air to flow over the rim with a minimum of separation resulting in lower drag. By adding this dimpled surface, you can expect to save 1-3 watts of power.
