Description
Niner's take on their cutting-edge cyclocross racing bike are clear: responsive, light, laterally stiff but horizontally compliant, disc brakes, and quick handling. The match of a SRAM 1x11 road groupset flows nicely into this concept. All of these characteristics are exemplified by the BSB 9 RDO Rival Bike, a svelte carbon frame and fork built for with Maxle style thru-axle dropouts. The super reliable Rival 1x11 Hydraulic Disc Road groupset is a perfect choice for a the destructive conditions of the average cyclocross course. It is cost effective to replace parts, and truly reliable and durable at impact and under extreme physical stresses.
Cyclocross has changed in the last few years. Carbon as a frame material has made frames stiff and light; even more durable in some ways than the lightweight alloy and Scandium framesets that preceded the carbon influx. Oversized head and steerer tubes made forks stiffer both laterally and vertically. Advances in disc brakes, as well as rim construction and greater rim width immediately applied naturally to cyclocross. The tubeless generation afforded tire options and exceptionally low pressures found on tubular tires. Even tubular rims and tires adapted to the new equipment standards. Rider technique evolved as well. Stiffer bikes and forks changed they way riders attacked corners, jumps, and hops. Lower tire pressures and wider rims broadened the overall traction capabilities, allowing riders to truly rely on lateral rigidity in off camber action, knowing the tire could hold the line, even in slick or muddy conditions. The skills of riders are constantly developing and pushing these technologies.
Enter the BSB 9 RDO frameset. Niner's Carbon Compaction System (CCS) optimizes the carbon lay-up and reduces excess epoxy to keep the disc brake specific frame weight under 1000 grams (Small), and the carbon disc fork comes in just over 500 grams (uncut). The 142mm/12mm thru-axle system in the rear and gently curving stays keep the back end stiff and light, through the oversized, full carbon PF30 bottom bracket shell. The front triangle offers shapes and planes that are cyclocross specific for easy carry, but also provide horizontal compliance while retaining incredible power transfer and torsion resistance through the oversized head tube. Combined with the tapered steerer of the Niner RDO cyclocross specific fork, the front end offers precise, confident handling. The fork itself is a full carbon design that draws on the company's years of experience with XC carbon MTB forks, and is laterally stiff down through the 100mm/15mm thru axle mount, yet absorbs vibration and chatter to smooth out the ride as much as possible....
