ENVE's original M60 Forty HV wheels left little to be desired in an all-purpose trail shredding wheelset. The ENVE M635 29in Boost Wheelset takes the best attributes of the original MSeries and bumps up the internal rim width from 26 to a substantial 35mm perfectly, pairing it with larger volume tires ranging from 2.5 to 2.8-inches wide. On this particular model the hub width comes in the 110/148mm boost standard. The larger tire volume and increased wheel stiffness afforded by the boost hubs make the M635 wheels the premium choice for launching huge gaps, dropping into rough chunder, and cleaning steep, technical climbs.
The M635 looks to the M7 and M9 wheelsets for the proper laminates to arm the aggressive trail rider with a capable wheelset to send it, but still wants something to efficiently climb into remote locations. The M635 is built for the same trail abuse as the M630, but comes in slightly heavier due to the increased width. Again, if you are looking to outfit your trail bike with wider 2.5 to 2.8-inch tires, these are the wheels you want. The newly redesigned wider hookless bead is both lighter and more impact resistant than the hookless beads that first appeared on the original MSeries. Additionally, the increased girth provides for a better buffer when the tire bottoms out, preventing the dreaded tire pinch flat. The 35mm of internal width allows for a large footprint that increases cornering stability and puts more tread to the trail at any given time.
All ENVE wheels, including this M635 utilizes patented manufacturing techniques building a strong, stable wheel that is ready to get rowdy out of the box and throughout its lifetime. ENVE's trademarked process of molding in-spoke holes, nipple seats, and valve holes is largely responsible for its proven reputation of creating wheels boasting one of the highest strength-to-weight ratios in the industry. ENVE molds carbon fibers around each hole to maintain continuous fiber integrity rather than drilling after curing, which results in increased rim rigidity, lower weight at the spoke face and superior spoke alignment.
This system also affords higher and more uniform spoke tension, keys to building true and long lasting wheels. Additionally, ENVE's build process removes the inner bladder, resulting in lower weight and a better balanced wheel compared to the many composite manufacturers who simply leave the rim-shaping, inflatable bladder in the rim once it's complete. The removal process is tedious, but it results in a lighter rim and the additional attention to detail is nice.
The rim is certainly the highlight here but other details are also worth mentioning. First, the wheels are built under one roof in Ogden, UT to exacting standards for the longevity you’d expect out of a class-leading wheel manufacture. Second, the wider, boost spaced hubs make for sure tracking up front and increased responsiveness out of the rear of the bike. DT Swiss 240 hubs are the benchmark for lightweight, durability, and tool-free maintenance. The star ratchet freehub internals are built to the same quality reminiscent of certain timepieces hailing from the same country of origin. You'll appreciate the smooth rolling bearings and years of trouble free service from these hubs and wheels as you blaze new trails and constantly push your limits. Centerlock and 6-bolt options are available as well as HG freehub and SRAM XD drivers.
