Description
Our most aerodynamic non-disc racing wheelset, the 404 is crafted especially for people who demand the ultimate performance this side of disc wheels without trading the ease of clincher tires, and who expect the kind of all-day comfort that makes it easy to train and race on the same wheels.
You have to love the convenience of today's clincher technology. Now you can love the performance even more with this year’s 404 Clincher wheelset. The 404 clincher is great for both Roadies and Triathletes alike. Any rider looking for the highest aerodynamic performance in a clincher race wheel, who wants to race and train on the same wheelset and who demands light weight and durability will find the 404 clincher the ideal choice.
* The pioneer in structural co-molded carbon fiber rims with welded and machined alloy braking surface, M2cm technology has produced a lighter, stronger, stiffer and yet more comfortable rim than ever possible before. An ICT process Carbon Fiber rim element is hand built and molded inside the precision alloy extrusion in a single seamless procedure. The dissimilar materials are melded into a unified whole that exhibits the best properties of each. There are no shortcuts in this demanding process; what you get is the result of hours of meticulous hand labor married to cutting edge technology.
* At 180 grams, the 404 aluminum extrusion achieves a variance of plus or minus 1% in extrusion weight where the best previous industry standard was plus or minus 10% on conventional rims. The result is the lowest rotational rim mass of any alloy clincher available, which means quick acceleration and efficient transfer of power courtesy of lateral stiffness more than double that of any conventional rim.
* The reduction in vibration frequency provided by Zipp’s 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.
* The 404’s multi-patented rim shape is designed to offer the best aerodynamic performance over the widest range of real world conditions using a range of available tires. After exhaustive testing, the 2004 404 clincher rim shape has yet again been refined to better exploit current tire technology, resulting in slightly lower drag numbers without change in lateral stability in even the fiercest cross-winds, and as a bonus, the new rim shape is laterally stiffer by nearly 8% as well.. No other manufacturer goes to such lengths to ensure maximum performance.
Highly Recommended:
ZIPP highly recommends the use of ZIPP Carbon/Carbon brake pads for all ZIPP rims and wheelsets. ZIPP Carbon/Carbon pads are engineered for optimal performance and rim longevity under all (including extreme) conditions with both Silica-Ceramic and Aluminum braking surfaces. ZIPP Carbon/Carbon pads are also recommended for use with non-ZIPP products. To find out more about ZIPP Carbon/Carbon pads click here.
Other recommended pads are KoolStop Black pads.

Zipp 404 (Clincher) Review
Reviewed by: trithis04, Sun Sep 04 2005
Pros: Fast aero wheel that that takes a beating. Can double as a trainer/race wheel with a different set of rubber.
Cons: Heavy in comparison to the tublar; +200g. vs. tublar counterpart. Zipp does not offer the dippled sufface on 650c sets for 2005.
No joke, these wheels move! I was able to push a close to 20 mph on the IM LP course with this setup. They are an extremely versitale wheel. They offer the ability to train and race on the same wheel set is so desired. And they enable the use of various rear wheel combinations (808 or disc) to compliment the course, terrain, or conditions. A great choice of long course racing, you can run a 23 or 21 tire to suit your personal preference. They really do handle varied terrain well. Fast on flats and light enough to climb well.
