ENVE's original M70 Thirty wheelset ticked all the boxes for hard riding, adrenaline chasing trail shredders. The ENVE M70 Thirty HV 29in Boost Wheelset retains all the things we love about the standard version and puffs up the internal rim width from 25 to 31mm to pair perfectly with larger volume tires ranging from 2. 3 to 2. 5in wide. ENVE also increases the hub width to meet the new 110148 Boost standard. The extra tire volume and overall wheel stiffness afforded by these changes make the M70 Thirty HV wheels the ideal set of hoops for conquering big drops, carving berms, and cleaning steep, terrain riddled climbs. The M70 Thirty HV Boost borrows downhill specific laminates from its M90 cousin to target the daredevil all mountain rider with a penchant for gravity speed who still wants the option to climb efficiently when the lifts are closed. The HV model weighs a bit more than the standard iteration, but it's still among the lightest wheels we'd pair with a six inch enduro bike. The redesigned, hook less bead is both lighter and more impact resistant than a standard, hooked bead, and the extra width allows for higher tire volume, increasing cornering stability and putting more rubber on the ground at any given time. As with all of its wheels, ENVE utilizes its Smart system to create a strong, stable wheel for any conditions. A patented process of molding in spoke holes, nipple seats, and valve stem holes is largely responsible for ENVE's proven reputation of creating wheels boasting one of the highest strength to weight ratios in the industry. ENVE routes the carbon fibers around each hole to maintain continuous fiber integrity, which results in both increased rim rigidity and lower weight at the spoke face. When laced to a hub, this system facilitates higher and more uniform spoke tension than standard bladder molding. Additionally, ENVE uses a process that eventually removes the inner bladder, resulting in lower weight compared to the many composite ma...
