Niner launches a boost rocket

29er specialist Niner launches a new race weapon with the "Rkt9 RDO" bike. The abbreviated name stands for Rocket and the times on the cross-country circuit should be correspondingly short. The new bike puts the Boost standard in the limelight.

In the past, Niner sent the "Jet9" to the race track, but this bike, with 100 millimetres of travel at the rear, with appropriate tyres and a 120 millimetre fork, could certainly be used as an agile trail bike. With the new "Rkt9 RDO", Niner is once again providing racers with a purist machine that wants to be one thing above all else: fast.

In order to achieve this goal, the Californians have injected new technology into the new bike: first of all, the Boost dimension on the rear triangle should be mentioned. With 90 millimetres of travel and a tire clearance of up to 29x2.4", the chainstay is a short 439 millimetres. Niner claims that such short chainstays and tire clearance up to 2.4" can only be achieved thanks to Boost. According to Niner, the wheels and rear triangle also benefit from more stiffness thanks to the 148x12mm rear wheel axle dimensions, i.e. the Boost dimension. As a comparison: the Niner "Jet9" bike with 100 millimetres of travel and X-12 rear suspension rides the trails with a chainstay length of 455 millimetres.

The rear triangle is built using "CVA" technology, which allows a constant wheel lift curve, is characterized by the link under the bottom bracket and enables the decoupling of suspension and pedalling forces. The bottom bracket is in the 73MM PF30 dimension and clears the way for single and multiple chainring sets. If you don't like press-fit bottom brackets, you can also use threaded bottom brackets on the "Rkt9 RDO" via adapters. The fresh Niner rocket is designed for forks with 100 millimetres of travel, resulting in a steering angle of 71 degrees.

Niner uses the same carbon processing method for the "RKT 9" as for the "Air 9 RDO" and "BSB 9" bikes; the manufacturer promises a stiffer frame with less weight thanks to this process. The Swiss Niner supplier offers the "RKT 9" in XTR 1x11, XT 2x11 and 1x11 and Sram X01 1x11 with XT Disc versions. The price starts at CHF 5,695.
