Let the fun begin.

The Niner 2015 BSB 9 RDO 5-Star Ultegra Di2 Hydro Complete Cyclocross Bike espouses the mantra of 'crossers around the world with its clever acronym BSB, which stands for Blood, Sweat, and Beers. However, don't be thrown off by the bike's party hardy namesake. The BSB 9 RDO is strictly business when it comes to delivering uncompromising race performance with its superb ride quality and rocket-like acceleration.


Borrowing heavily from Niner's podium-crushing XC hardtail, the AIR 9 RDO, the BSB 9 RDO features a full carbon frame with flat surfaces along the top and down tube for enhanced torsional rigidity. These flatly sculpted tubes not only help you rocket out of corners when you're racing, but they're also great for shouldering the bike over course obstacles. The chain and seatstays are also heavily influenced by the AIR 9 RDO, delivering a smooth, supple ride over rougher terrain without sacrificing power transfer to the rear wheel. Moreover, you'll find Niner's full carbon RDO Cyclocross Fork, which delivers high levels of stiffness with its tapered steerer and 15mm thru-axle.


Naturally, the BSB 9 RDO is disc brake only, and the 5-star build is no exception. Its Shimano RS785 hydraulic disc brakes provide reliable stopping performance in the nastiest, muddiest conditions experienced in 'cross racing. The next-level Shimano Ultegra Di2 electronic drivetrain laughs in the face of mechanical-impairing muck and debris, with its battery neatly tucked into the seatpost. Speaking of seatposts, Niner uses its RDO Carbon Seatpost for high levels of comfort in the saddle, flexing as much as 6mm to dampen fatigue from rough courses. Additionally, the bike is equipped with Niner's ultra-light, but incredibly durable, CX Carbon wheels for snappy acceleration and dental plan-saving strength.
