The clincher version of the 404 uses the same go-anywhere, win-anything 58mm rim depth of its tubular brother, but with the everyday convenience of clincher tires and the reliability of an aluminium braking track.

Plus, Zipp's M2CM technology maximizes rim strength and durability by fusing the aluminium hoop to the inner carbon section. ABLC dimples, VCLC vibration-reduction technologies, and the new 88/188 hubset round out the 404 Clinchers' 1615g total package with 16/20 front/rear spoke counts.

• ABLC: Advanced Boundary Layer Control (ABLC) refers to the patented and instantly recognizable dimpled pattern found on most of our rims. ABLC smooths airflow across the rim's surface and is tailored to every model from the 202 to the Sub9 disc. 2009 sees the third-generation of ABLC, with up to 4 times more dimples than before.
• VCLC: 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.
• M2CM: 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.
