TR 307 Boost Wheelset

Offering a warm welcome to those who'd like to save a few dollars, but don't like to compromise quality, Reynolds introduces the TR 307 Boost 27.5in Wheelset. Built to charge hard, these hoops are crafted from the same over-built and burly carbon fiber of Reynolds' Blacklabel series, so you can cook it into banked berms and chunky rock gardens alike with total confidence, but feature a house-made CNC machined hub to knock the price down a few digits. The rims themselves are stretched out a bit to accommodate loftier tires than you'll find on the traditional Blacklabels, allowing you to enjoy a plusher ride and a touch of pneumatic suspension when chattery trails unfold ahead of you.


The TR 307 wheels are built with asymmetrical rims that we also saw on the Blacklabel series, which enables a stronger wheel through more even spoke tension. This translates to a ride that powers through the rocks without deflecting if you pick the wrong line and would otherwise get bucked around. When combined with the wide, Boost spacing, the wheels strength truly shines through with an evenly tensioned wide angle to keep you locked into your line no matter what. While Boost may not be news to quite a lot of us, it's worth reiterating how it works: by setting the hub flanges wider, Reynolds is able to improve the spoke bracing angle, which stiffens the wheels laterally and torsionally (translating braking and pedal input from the hub to rim to trail) without stiffening them radially (so the wheels don't translate every bump and root straight up the seatpost). While bumps and trail chatter are less of an issue with such a wide rim, we're generally under the assumption that less of a bad thing is a good thing. Adding 28 straight-pull spokes to the mix, you'll find lasting durability, and just the right amount of flex, so your wheels don't feel harsh through wily rock gardens.


Like the Blacklabel and TR-S series, the TR 307 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.


In addition to being strong, the rims feature a wide profile capable of accommodating the plusher tires that have been afforded by the addition of boost spacing to bikes. The rim's internal width lands at 30-millimeters, which most of us here in the office are in agreement on being the optimal rim width for enduro and trail rigs. This width allows for running wide, but not plus tires, with our happy place being 2.5-and-2.6-inch tires that allow us to run slightly lower tire pressures around 18psi for gripping loose corners and soaking up beefy roots and rocks, but without gaining rolling resistance the way most ultra-plush 2.8's do.
