Merciless speed.

The Niner BSB 9 RDO Frameset is a purpose built cyclocross machine that makes no apologies in its unrelenting quest for speed. Standing for the catch phrase "Blood, Sweat, and Beers," the BSB 9 RDO satisfies the cyclocross racer seeking a nimble-handling rocket for all-out sprints across the finish line, hectic hops over barriers, slogs across sand pits, and refreshing beer hand-ups. New for 2018, the latest model gets updated with flat-mount discs, as well as two opposing colorways for bold and stealth-minded racers alike.

Carrying Niner's Race Day Optimized carbon frame, or RDO for short, the BSB 9 RDO benefits from an unbelievably stiff, lightweight construction for uncompromising acceleration the instant you turn the pedals. RDO carbon benefits from Niner's Carbon Compaction System (CCS), in which a rigid internal mold provides a tighter, more consistent compaction of the carbon layers during the manufacturing process. Ultimately, this cutting-edge manufacturing process gives Niner's engineers the ability to dial in the exact traits they're after, namely unrelenting stiffness, high levels of strength, and ride quality.

Racier geometry makes the BSB 9 RDO stand apart from the gravel-oriented RLT (Road Less Traveled) model from Niner. You'll find the BSB 9 RDO has a steeper head tube, higher bottom bracket, shorter wheelbase, and snappier chainstays than the RLT, giving it much quicker handling, more pedal clearance, and a racier overall feel. The frame's flatly sculpted tubes enhance the bike's torsional rigidity, and also makes it easier to shoulder over course obstacles. Thru-axles at the front and rear improve the precise tracking of the bike, especially when you factor in the exceptionally stiff Niner RDO carbon fork with a tapered steerer. Internal routing cleans up its overall aesthetic while keeping everything protected from flinging muck and debris. Additionally, it's compatible with electronic drivetrains, adding a futureproof element to this cyclocross bike.
