Why We Like The Hydra Trail S 29in Boost Wheelset

Get ready to hit the trail at warp-speed with Industry Nine's new Hydra Trail S 29in Boost Wheelset. These fancy new hoops combine the classic Trail rim with the quickest new hub on the block — the I9 Hydra, which offers engagement that's so quick you won't know you even put the power down before you start rolling forward. That's because the hubs took some tech from the classics that came before it, and rolled right into the future with 690 points of engagement that propel you forward with 0.52-degree engagement, for the fastest hub we have yet to see on the market. This particular wheel build laces up Hydra hubs with I9's alloy Trail rims using straight-pull steel spokes, designed to simplify the build a bit, dropping down the price, so you can keep some of your upgrade budget safe for other components.


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 rims to the Hydra hub using the more economical steel spokes, which is where this wheelset gets its "S" designation. The high-performance straight-pull system still offers stiff control with 28-spokes, but with a more conventional, approachable package that fits the pocketbook of those of us who don't want to blow this year's bike-upgrade-budget in one place. 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.

Top Tier Wheelset

Familiarity:
I've used it several times

Didn?t realize Industry Nine was a top tier wheelset brand, in particular the Hydra hubs, until I read articles, watched YouTube reviews, and received compliments from others. I was a bit concerned about rolling resistance of the freehub body, but that was an issue with the previous model, the Torch. There seemed to be some rolling resistance when spinning the wheel on my bike stand, but hard to tell on the trail. By the 3rd ride of about 10 miles each, I noticed a difference in freehub resistance. It definitely seemed to coast much longer on the bike stand, but I could notice the difference on the trail. They just seemed to roll real nice compared to the stock DT Swiss XM 1900 wheels I had previously. I noticed right away the handling. My previous wheelset had a 30mm internal rim width, which is great if you?re pointing the wheel south to do some gnarly terrain with big drops, but for XC and trail terrain, the 27mm inner rim width of the I9, is more responsive and easier to control through technical terrain and switch backs. Setting up the wheelset to tubeless was the easiest setup I?ve ever done. It was so easy that I didn?t have to use soapy water or remove the valve core to blast it with air from my compressor. I mounted the tires and used my floor pump, that was it. After four rides the tire pressure held with no leaks without using sealant. Ah the engagement....didn?t know this was a hot topic with aftermarket wheels until I read the reviews and found the I9 Hydra is the gold standard when it comes to the most efficient engagement. I didn?t realize how bad my DT Swiss stock wheels were until I mounted these I9?s on my bike and actually went on the trail. It?s like comparing a 720 to 4K TV high definition. The 720 is ok because you don?t know any better, but once you get that 4K, nothing else compares. The Hydra?s engagement is instantaneous, I mean there is no noticeable play in the engagement from the moment you mash down on the pedals to when the rear wheel puts power to the ground. The I9 Hydra?s buzzing is adjustable by either applying a specific brand of thicker grease to the pawls to make them more quiet, or oil to make them more audible. I prefer the stock grease with a subtle buzzing that is very distinctive. If you?re like me and think the sound will annoy you, it doesn?t at all and it sounds quite cool and unique. Looks, they are absolutely cool looking wheels and the rims are equally impressive. The rims have a pattern what appears to be lasered on the surface that is unique to I9, and the laser etching on the hubs surface is precise and pops with the black anodized finish of the hub shells. So far I have been impressed with these wheels after only four rides and hope they continue to impress as I rack on more miles Cheers!
