Details: Pushing to empower more riders with light and nimble carbon hoops, the designers at Reynolds have crafted up their new TR 309 Boost 29in Wheelset for all-mountain charging, enduro hard-hitting, and with a slightly smaller price tag to accommodate more riders upgrade budgets. They start with a set of the same hoops employed on Reynolds' Blacklabel wheels, with stiff, over-engineered carbon fiber that offers reliable tracking and durability on the trail, and are stretched outward to accommodate a loftier tire for floating through the chunder before lacing up to a set of Reynolds' own CNC machined three-pawl hubs for quick actuation that doesn't drain the wallet. Like its big brothers, the Blacklabels and TR309S, the TR309 uses Reynolds' Mountain Rim 5 (MR5) carbon fiber layup. This layup involves five different carbon matrices applied to five different areas of the wheel. A decidedly serious carbon layup -- this construction process is more complicated than many frames, placing specific matrices to maximize strength. And though we don't often dwell on the possibility of equipment failure while blasting berms and charging into lines that are a bit too rowdy, the fact that Reynolds puts so much engineering into the rims helps ensure that we won't have to dwell on equipment failure. For months. While wearing a cast and saving up for a new wheelset and/or bike. Focusing on a friendlier price point than the deluxe Blacklabel line, and the mid-range TR309S, the designers are Reynolds went for a dive into hub creation for the TR309, capable of exceptional performance without the somewhat painful price tag that comes along with some other hubs. Using CNC machining, they created the Reynolds TR3 hub, cut from aluminum in one piece to ensure strength, and features three phased pawls to propel you forward, with just 10-degrees of engagement, so the wheels carry you with the responsive and light-on-the-feet feel you want for quick power bursts up punchy climbs, or chomping at...
