Niner BSB Rival 1x Jenson Bike

Blood, Sweat, & Beers! The embodiment of cyclocross

From its weight-saving Carbon Compaction System frame production process, to its shouldering friendly geometry, the BSB is fine tuned in every way for life between the tape, under the beer showers, and atop the podium.

As the BSB graces the cross scene with Niner's beloved mountain bike heritage, it also introduces a cutting edge carbon fiber frame production process known as Carbon Compaction System. It uses a pre-shaped Styrofoam mold encased by a bladder that the carbon is then laid around. The firm Styrofoam core provides the desired shape of the frame and a solid platform for the carbon. The bladder is then inflated to fully compress the carbon against the outer metal mold for accurate compaction and a smooth inside wall. Resulting in a stronger, lighter weight frame with fewer potential weak spots.

The overall shape of the tubing is intensively designed to meet the demands of cyclocross racing, including the iconic art of shouldering the bike. Cross-junkies will find friendly flats, comfortable shoulder positioning and attentive placement of cables to aid in the best cyclocross technique. The sub-1000 gram RDO carbon layup race frame offers unfathomable amounts of stiffness for slogging through mud and kicking up fly-overs. Featuring a cross-specific geometry, including a steep head angle, the BSB will see you through tight corners and sprint finishes, while the bottom bracket height is specific to crank length for better clearance on off camber course features. Niner applies their rigid carbon fork expertise into the BSB's front end to offer the off-road ride quality that dedicated cross racers need to thrive. The BSB fork combines the tapered head tube with the 15mm front axle for unmatched front end stiffness and maneuverability. The flatter edges on the fork enhance lateral stiffness and prevent race-killing brake rub.

The Niner BSB Rival 1X Jenson bike will arrive on your doorstep with a race ready set of components including, a SRAM 1X drivetrain, with Rival 1 shift/hydraulic brake levers, a SRAM Rival 1 crankset, 11 speed cassette and rear derailleur. SRAM hydraulic brake calipers and rotors keep the speed in check and put all the stopping power right at your fingertips. The Easton EA70 wheels are wrapped in Schwalbe Racing Ralph 33mm wide rubber and Niner bar, stem, carbon seatpost and SDG saddle handle all the cockpit duties.
