The clincher version of the 404 utilizes the same go-anywhere, win-anything 58mm rim depth of the tubular model but offers the everyday convenience of clincher tires and the reliability of an aluminium brake track.
For greater strength and reliability, Zipp's M2CM technology fuses the aluminium hoop to the inner carbon section during the molding process. Still, the 404 clincher’s 1658g total weight is less than many full-carbon clinchers. Of course, none of those other wheels offer Zipp’s exclusive features like ABLC dimples, VCLC vibration-reduction technologies, and the smooth, stiff, durable 88/188 hubset.
ABLC™ (Aerodynamic Boundary Layer Control): Advanced Boundary Layer Control (ABLC) refers to the patented and instantly recognizable dimpled pattern found on most of our rims. ABLC smoothes airflow across the rim's surface and is tailored to every model from the 202 to the Sub9 disc.
VCLC™ (Visco-Elastic Constrained Layer Control): Visco-Elastic Constrained Layer Control (VCLC) uses a vibration-absorbing material sandwiched between layers of rigid carbon laminate in the rim. When the wheel receives an impact from the road, much of the shock is absorbed by the VCLC system, delivering a 10% reduction in vibration. Read More
M2CM™ (Multi-Material Co-Molding): Multi-Material Co-Molding (M2CM)ensures that Zipp clincher rims are the world's strongest. The process permanently fuses a sub-200 gram aluminium hoop to a carbon structure with the same dimpling as our tubular rims and our patented toroidal bulge, which acts as a leaf spring to reinforce the aluminium during impacts. The spokes lace directly to the carbon body for a fully structural rim that blends the ride feel of carbon with the braking performance of aluminium.
88/188 Hub Technology: Every aspect of our 88 and 188 hubs sets a new benchmark. The standard steel bearings are the roundest in the industry. The 17mm axle is the stiffest of any road hub we've tested. The wire EDM-cut hub internals are the most precise. The SHIFT spoke hole technology is the most durable. When it comes to precision and performance, there's really no comparison
