Riding is believing with the Zipp 1ZERO HITOP SW MTB wheelset when it comes to making you faster. Trail compliance is vital, with modern cross-country races becoming rougher and more challenging. No longer is it good enough for an XC wheelset to be stiff above all else. Instead, a wheelset should feel alive. The 1ZERO HITOP SW carbon rim complies with the terrain thanks to Zipp's proprietary HITOP Technology for carbon layup. The result is a lightweight XC wheel that carries speed through all sections of the trail, rocks, roots, and ruts with the durability required for a trail bike with up to 130mm of travel. A compliant wheel provides more confidence. You don't have to work hard to spin it up to speed or fight your bike when things get chunky. The 1ZERO HITOP SW also comes with the TireWiz tire-pressure monitoring system, so you'll always have your tire pressure dialed in for optimal performance. Among the lightest on the market, the ZM2 SL hubset ensures you'll be quick to accelerate and back on the pedals sooner after corners with the 1ZERO HITOP SW. - HITOP Technology produces proprietary rim layup to provide compliance and confidence when the trail gets rough - Low weight for effortless accelerations and climbing - Winged rim provides a smooth resting surface for the tire, reducing the chance of pinch flats after a rock hit - TireWiz 2.0 tire-pressure monitoring system features a seamless design - ZM2 SL hub with 66 points of engagement - Standard or Torque Cap options on the front hub - XD or Microspline driver-body options - Lifetime Warranty

The definition of "road cycling" now includes gravel and dirt as well as pavement. At the same time, bikes are evolving to meet the fit requirements of smaller riders. Meeting these two distinct needs was the driving force behind the Zipp 303 Firecrest 650B Tubeless Disc-brake wheelset. The smaller rim size provides room within frames and forks for larger tires that deliver increased comfort, compliance, and cornering performance. With more tire between the rim and the ground, the overall wheel diameter, including the tire, is similar to a standard 700c wheel and road tire combination. Back on the pavement, the 650B is a better-fitting wheel for smaller athletes riding compatible frames. For too long, many smaller cyclists have trained and raced on standard 700c wheels, losing out on the advantages of a proper fitting wheel such as improved handling and the elimination of front wheel-toe overlap. At the center of the 303 650B Firecrest Tubeless is a versatile and durable hubset, the German-engineered ZR1 DB. - Zipp graphics and cosmetic identity that scream speed - Versatile 45mm rim profile for increased speed and better cornering, control, and comfort - Tubeless design provides secure performance when ridden at lower tire pressures - ZR1 DB hubset is engineered in Germany with better seal design for improved durability and quicker response with 66 points of engagement - Built with Sapim CX Sprint J-bend spokes - Center Lock rotor interface (lockring included) - Ships with 12mm end caps
