With a new name and a redesigned rim profile, the Industry Nine Trail 245 27. 5in Boost Wheelset updates Industry Nine's popular Trail series, making wheels already known for their longevity even more durable and better adapted to the modern, 27. 5in standard. Built with the same reliable construction and precise machining that Industry Nine has become known for, this version is compatible with Boost front and rear axles. Industry Nine starts with dependable aluminum rim construction for the Trail 245s, increasing the internal width to 24. 5mm and giving the rim its new Second Generation Tubeless profile. This means wider bead seats and a shorter, more tapered bead wall overall, a more flared shape to improve the tires' flat resistance at low pressures. The ever expanding girth of 27. 5 tires is better accommodated by this profile, and the reinforced rims enjoy more dent resistance and overall strength. Though they create stronger rims, these changes don't result in a drastic weight difference, adding only 20g to the entire setup compared to the previous version, and they result in a rim that's well suited to the do everything capabilities of a 27. 5in platform. Industry Nine's signature hubs are largely responsible for the brand's enthusiastic following, and the latest Torch hubs used in the Trail 245s don't disappoint. They're laced to the rims with Industry Nine's machined 7075 T6 aluminum spokes, which thread directly into the hubs. This distinctive choice eliminates weakness at the spokehub interface and allows for increased surface area for a stronger wheel system overall. The hubs themselves rely on Industry Nine's proprietary pawl design, which features two sets of three pawls phased three degrees from each other to provide 120 points of contact and a snappy three degrees of engagement. The rear hub was tested to withstand an excessive 700ftlbs of torque roughly what a diesel truck puts out which should put any thoughts of slippage or power l..
