Ultralite CX 235 TRA 650b Wheelset
As more and more riders adventure off the beaten path on their drop bar bikes, they are discovering the benefits of running smaller diameter, yet higher volume tires at lower pressures to find additional comfort and traction over rougher gravel roads. So just as we've seen with 27.5+ wheelsets and tires sneaking into 29er frames boosting compliance and grip, drop bar enthusiasts and racers are putting "road plus" setups on their bikes and that’s exactly where Industry Nine sets its aim with the new Tubeless Ultralite CX 235 TRA 650b Wheelset. With an internal rim width sitting at a healthy 23.5mm, it provides an optimal foundation for 33 through 55mm tubeless tires, allowing them to plump up and take on a more natural profile for secure cornering on loose gravel and greater comfort over those washboard braking bumps.
What was instrumental in I9 developing these wheels was the fact that many riders want to run 650b on their gravel bikes, however, most of the wheels on the market are built for 27.5in mountain bikes. A few issues arise here with that. Many of these wheels are overbuilt and designed for the needs of mountain biking, so you'll be lugging around extra weight that’s not necessary. Another is the hub and axle compatibility. If the hubs are designed for a 9 through 11-speed mountain cassette, it won't accommodate a subtly 1.8mm wider 11-speed road cassette and while many mountain bikes have gone to stiffness and geometry enhancing Boost spacing, most drop bar bikes have stuck with 100 and 142mm spacing front and rear.
Therefore, Industry Nine takes its 235 mountain-going rim and laces it to its new TRA, or Torch Road Alloy, Centerlock hubs with its signature alloy spokes in a 2:1 lacing pattern. This clever design cuts weight and better balances tension so you have better handling wheels that last longer. The rims ideally pair with the 2.1-ish mountain rubber that many folks are running, while the hubs are fully compatible with HG road, XD drivers, and 12x100/12x142mm and 15x100/12x142mm frames and forks.
I9 is industry-acclaimed and proud of its precision CNC machining and beautiful anodization at its Asheville, NC facility, and its Torch hubs and alloy spokes are a shining example of this craftsmanship. The Road Torch freehub is built around a three pawl system that provides 60 points of engagement so it's never more than six degrees away from translating your pedaling input into forward motion, a boon on loose terrain. These wheels and wider tires will open up your mind to what a drop bar bike is capable of.
