Handbuilt Wheels: Industry Nine Hydra, Blue, Boost, XD driver

The i9 Hydra hub has become a go to for demanding MTB riders. Produced domestically in Asheville, NC the Hydra hub is available in a variety of colors to accent your build.

The Industry Nine Hydra freehub engages every 0.52 degrees. It features 690 points of engagement from a 6 pawl, 6 phase drive and a 115 tooth drivering. The elimination of lash or buildup to the freehub also improves the hubs service life.

Another popular feature of the Hydra hubs is their ability to be services without proprietary tooling making it easier for home mechanics to get back on trail.

Our hand-built Hydra wheels can be built with a variety of popular rims. If you don’t see what you’re looking for contact our team for details on availability and pricing!

Rim Width Choices

Rim width will change overall tire volume and shape.

30mm rims are popular to setup 2.3-2.6 tires.

The wider 35mm internal tend to be for riders in the 2.4 and bigger range.

With the wider internal the tire volume is increased, allowing for lower riding PSI however the tire is a bit “flattened”. Narrower tires may find that the cornering knobs become a bit too vertical compromising some lean in angle.

DT Swiss Spokes & Nipples

Spokes & Nipples

We work with DT Swiss spokes and nipples for a variety of reasons.

Most notably, DT Swiss has unmatched quality control checks and balances which produce the most consistent spokes batch to batch of any manufacturer.

Nearly all of our wheels are currently built with DT Swiss Competition spokes.

We avoid hand-building wheels with bladed spokes for off-road use. The weight and / or aero savings are negligible in MTB use and unlike full radius spokes bladed spokes have an inherent stress riser in the shape making them more likely to damage from rock strikes, etc.

3 Cross vs 2 Cross

We offer both 2 and 3 cross lacing patterns.

Depending on your size, riding style, goals and applications you may find 2 or 3 cross your preference.

2 cross spoke lacing MTB wheel build

2 Cross Spoke Lacing

Called 2 cross as each spoke crosses two others. 2 cross lacing produces a bit more of a rigid, responsive build.

3 cross spoke lacing MTB wheel build

3 Cross Spoke Lacing

Each spoke crosses three others. 3 cross lacing adds a bit more compliance to the wheel build.

That compliance will generally increase your bike’s traction. The added compliance also helps reduce stresses on the spokes increasing the wheel build’s service window.

Most riders will prefer the 3 cross’ advantage of better traction and longer service life.

2x vs 3x spoke weight examples

3 Cross vs 2 Cross

Some of the other considerations in 3 cross vs 2 cross spoke patterns are the actual spoke length.

2 cross patterns use shorter spokes overall, but how much weight savings does that really equate to?

The image above shows 10 284mm spokes compared to 10 of the 3 cross’ 294mm spokes. You can see the weight saving isn’t as much as you might think.

If there is a 4g difference in 10 spokes you come out to just under 13g across 32 spokes on a wheel. In pounds? about 0.0287.

So, if the weight isn’t a factor it really comes down compliance and longevity.

Still have questions? Chat with our team about the details. (truth told, I really never did the research for myself – the guys asked my weight, knew what I rode and I’ve ridden 3 cross ever since!)
