Solix M TR300/290 DUO is the best light trail, aka “downcountry” wheelset to ever wear the Industry Nine name. From the Solix M system chassis to the DUO series premium carbon rims, every component in this wheelset is top-of-the-line, crafted to deliver a ride that transforms your bike into a wild climbing machine or a rocket ship on steep, gnarly descents, depending on which way the grade is trending.

Our DUO carbon series employ front and rear specific rims tailored to meet the unique demands that each rim will encounter. The TR300 front rim is 30mm wide internally, hookless, and handmade with a lay-up schedule that places compliance and lower weight at the forefront for decreased system weight, and optimal ride quality. Since rear wheels endure appreciably different situations, the TR290 rear rim is also hookless, 29mm wide internally, with thicker bead walls and a lay-up geared for reducing pinch flats, handling bigger impacts, and confidence in chunky terrain. Like all of our carbon wheelsets, a lifetime warranty for the original owner protects your investment.

The sturdy foundation on which the TR300/290 DUO is built is the all-new Solix M system chassis. Employing 605 points of engagement in our most compact off-road package yet, the Solix drive mechanism promises control everywhere on the mountain, from switchbacks on the way up, to baby-head traverses and off-camber corners as you chase daylight down to the trailhead. The integration of hub and spoke is a longstanding feature of Industry Nine mountain bike wheels, and Solix M continues this configuration - employing our direct-thread hubshells that mate to our one-piece, straight-pull machined aluminum spoke. This system creates a responsive ride quality and an unmatched stiffness-to-weight proposition available with our custom color palette. Trailhead to summit and back again, nothing will get you there like Solix M TR300/290 DUO.

Riders looking for the ultimate XC race wheelset will love the Solix M UL300. Our alloy counterpart, the Solix M TR285 incorporates many outstanding features into a more economical wheelset with an aluminum rim.

Industry Nine has gone the extra mile to ensure we offer the best Carbon Wheels available. We are so confident in our wheels that we are now offering a limited lifetime warranty on all carbon wheelsets sold after January 1, 2018.

The limited lifetime warranty applies to all Industry Nine branded complete carbon wheelsets. Under the limited lifetime warranty, Industry Nine certifies all wheels to be free from defects in materials and workmanship* and applies to the original owner.**

Industry Nine carbon wheel systems are engineered to be ridden every day and are designed and tested to ensure the strength of the wheels far exceed the loads incurred during their intended use.*** You can rest assured that if you are on an Industry Nine Carbon wheelset, we have you covered.

*The warranty applies to all original owners who purchase their wheels from an Industry Nine Authorized Dealer or directly from Industry Nine; wheels purchased through third-party sites are excluded from the warranty.

**Keep in mind that wheels (as with most moving parts) require periodic maintenance and service. Bearings are considered a wear item and if properly serviced, should last several years, but are not covered under the lifetime warranty. The exception is our Enduro XD-15 Hybrid Ceramic bearings (which are an upgrade option). Any wheel that has been altered, improperly maintained or installed, or modified from its original build will not be eligible for this warranty.

***If you are riding the wheels within the scope of their designated use, we have you covered. If you hit a tree at 30mph or come up short on a double while riding your road bike at the bike park and break a wheel - we have a great crash replacement program.
