101 Trail S 27.5in Boost Wheelset

Whether you're building up a new steed, upgrading your trusty bike, or you taco'd your hoop getting a little too wild, chances are you want a wheel that's true, reliable, snappy, and doesn't send you into a vegetative state when you look at the price tag. Industry Nine has long made some of the snappiest hoops we can get our hands on, and the new 1/1 Trail 27.5in Boost Wheelset makes a strong argument for itself when you want to balance durability, reliability, precision, and price. These wheels run with the same Trail S hoops you'll find laced up to the Hydra model, but with a different hub that cuts price down a few big bills. Internally it bares some similarities to the Hydra and its predecessor, the Torch, but is ever so slightly less snappy, with 4-degrees of engagement, which still blows much of the competition out of the water.

The 1/1 hub utilizes a 45-tooth spline, and six phased pawls that engage two at a time, making for 90 engagement points as you spin. We won't try to convince you that the 1/1 will feel as snappy as the Hydra, it measures in at 4-degrees of engagement as opposed to the 0.52 that the Hydra packs, but it does fallow closely to the ever-coveted Torch which was long revered as one of the snappiest wheelsets on the market — that is until I9's engineers had to go and out-do themselves. What this means is that power is nearly instantaneous when you hammer on the pedals, leaving little energy wasted, and a responsive feel through the ride. When it comes to tackling the mountain we don't think everyone should have to break the bank, and the designers at I9 don't think so either, which is why this particular model laces up the classic Trail S rims to the 1/1 hub using the more economical J-bend steel spokes, which is where this wheelset gets its "S" designation. The Trail rims used are the same you'll find in the higher-end builds, with lightweight construction, and a moderate 27-millimeter internal width that accommodates 2.2-to-2.5-inch tires, finding the balance between reduced rolling resistance and plush control in corners.
