The essence of cyclocross, and now the flagship drop-bar offering from Niner Bikes. Choice of Team CLIF.
 

The BSB 9 RDO is the sub-1000 gram race frame that will take you through every off camber corner, up every staircase, and into endless gauntlets of brew drinking, prime tossing, screaming, heckling fans - lap after lap after lap.
 

RDO CARBON COMPACTION SYSTEM
The BSB 9 RDO is beautiful from the inside out via Niner’s Carbon Compaction System. Now used throughout the Niner RDO lineup, this CCS utilizes rigid internal molds and results in tighter, more consistent compaction of the carbon layers, yielding increased precision in wall thickness and significantly reduced resin pooling in the final product, allowing us to aim for better ride tuning, increased strength and durability along with the weight reduction that results from a more efficient process. At sub 1000 grams for a size 56cm, the BSB 9 is competitive in any line up.

DESIGN
The shapes of our BSB 9 RDO frame are heavily influenced by our long history in carbon fiber race frame design – in particular by our experience in building light, strong hardtails with velvet-smooth off road ride-quality. 

PERFORMANCE GEOMETRY
BSB 9 RDO geometry reflects proper cyclocross geometry – a steep headtube angle for fast handling, a size and crank length-specific bottom bracket height for cornering and short chainstays (425mm) for technical maneuvers. Smaller sizes are designed to avoid toe overlap and larger sizes have bottom bracket heights specifically selected to reduce pedal strikes common with longer crank arms.

FORK
The BSB 9 RDO frame is paired with Niner’s new RDO Cyclocross Fork. Niner’s award winning rigid carbon forks have set the standard for weight, ride quality and safety for years – we’ve used this experience to create an cyclocross race fork with the off-road ride quality riders want in their race bike. Fork stiffness prevents energy robbing brake rub and the thru axle plus taper-steerer combo ensures precision cornering on the toughest of courses.

DISC BRAKES AND MAXLE/QR COMBO
The BSB 9 RDO is disc brake only - a natural choice for cyclocross, particularly in foul conditions. Racing frames must also be light without sacrificing performance - The BSB 9 RDO frameset uses a Maxle front and QR rear dropout combo – a design choice specifically made to keep frame weight down and steering precision high. While there were significant advantages in stiffness and steering to be had with a maxle front, there was no noticeable improvement in rear stiffness between the QR or Maxle option, so we’ve made the lightweight, better braking choice for racers.

CYCLOCROSS SPECIFIC DESIGN
Cyclocross demands ergonomic frame shaping and careful details. In addition to ride quality, the bike must be easy to lift, carry and shoulder. Riders will find friendly flats, comfortable shoulder positioning and thoughtful placement of cables to aid in the best cyclocross technique.

FINISH
Even our aesthetic choices were heavily influenced by the race-specific demands of the BSB 9 RDO. In order to reduce weight a further 40-50 grams, we’ve pared the paint down to the minimum, used ultra thin decals and a light satin clear coat for a protective layer.
