Why We Like The RKT 9 RDO 2-Star SX Eagle Mountain Bike

The best thing about not being sponsored is that we get to choose our own bikes, and some of the best riders in the world don’t have access to all the tech that’s crammed into the Niner RKT 9 RDO 2-Star SX Eagle Mountain Bike. Niner shows with the RKT that they’re all in on winning cross-country podiums around the country. Aggressive suspension and proprietary linkage build a hyper-capable machine for anything from short XC events to our next marathon stage race. It’s not all aggressive though, as the 90mm of CVA tuned suspension in the rear keeps things plush during the long-hauls.

Niner knows a thing or two about innovation, started in 2004 out of LA, they were one of the first companies to go all-in on 29” wheels. Improved rollover and a bigger contact patch means they’re outright faster at a minimal weight penalty. That innovation has carried over with the RKT 9 RDO, which uses Niner’s own CVA(Constantly Varying Arc) suspension system to give riders an ultra-predictable platform. Once we get used to how CVA rides and responds, we don’t think we’ll ever be going back to an alternative.

Geometry on the RKT 9 RDO is aggressive but designed around a plush 120mm fork, we still get a good dose of forgiveness when we’re sending it off stuff a bit too steep. Designed and ridden in Colorado, this bike is built for long, technical climbs, making sure every bit of effort we put into the pedals is transferred into getting us up the hills. With a demanding 70° head angle and slightly slacked-out 73.5° seat-tube angle, the bike pushes us to get out of the saddle and over the bars, going hard until all we can see is red and all we can hear is our heartbeat.

We knew what we were getting into with the RKT RDO 9, an aggressive cross-country race bike that yearns for KOM’s and podiums, and we’re not afraid to push ourselves to the absolute limit to meet those demands. Fox suspension performance lifts the RKT up, and when the trail tilts down it supports us over anything we can get ourselves into. The 2-Star build is built around the same carbon the 5-star builds get, so don’t be afraid to upgrade the bike overtime as you’ll still get the same responsive and stiff carbon layup the big dogs enjoy. The RKT 9 might not be our next trail bike, but it will be the bike that gets us on the top step of coveted cross-country podiums.
