Blood, Sweat and Beers
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.
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. Informed by, but not slave to, the shaping of the Air 9 RDO – you will find generously sized downtube and top tube shapes for torsional stiffness, with vertical compliance achieved via the flat sections on each tube. Chainstay and seatstay shaping also benefits from our hardtail expertise – they are one hundred percent designed for weight savings and ride quality – something not previously possible in cyclocross when reinforcing for cantilever brakes. Our seat tube fits a 27.2 seat post, continuing the theme of rider-comfort and is well-paired with the Niner RDO Setback Post for maximum flex and minimum chatter when in the saddle.
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.
Our robust R&D program—computer modeling, physical prototype testing (both in-house and at independent testing facilities), and hours of ride testing under highly skilled and abusive test riders leave us confident that the BSB 9 is going to exceed your expectations. We maintain that our carbon fiber testing and design rivals the best in the bike industry. Rather than just talking about it, we choose to demonstrate this commitment via our C5 warranty (five year) and commitment to customer service.
PRESS FIT 30 BOTTOM BRACKET
The BSB 9 RDO utilizes the Press Fit 30 standard, the larger shell mates beautifully with the larger carbon downtube for elegant looks and efficient power transfer so crucial in a race bike. Additionally, this allows for the use of the stiffer, lighter crankset designs that fit the PF30 standard.
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.
There are no guides inside the front triangle – external rear brake routing on the side of the downtube keeps everything out of the way when shouldering. We utilize full length housing front and rear for clean crisp shifting in the worst winter conditions. Internal routing with large access windows makes for easy mechanic maintenance as well as simple Di2 routing for those choosing electronic shifting options. When you are on the bike, the post mount rear brake helps to prevent heel strikes and brake rub – keeping you fast and efficient. Every size of the BSB 9 RDO fits two water bottles for proper hydration when racing or training.
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. The BSB 9 is available in Black/Niner Red – as raced by Team CLIF Bar Cyclocross and MTB, and in Ice Blue, soon to be piloted by Niner rider, Chloe Woodruff.
HOW DO YOU DECIDE - RLT 9 vs BSB 9?
Niner’s RLT and BSB offer different advantages to riders
The BSB is a born and bred cyclocross racing machine for riders seeking every advantage. The ultra light carbon frame is pared down to the basics to keep the weight down - even the paint is minimal. The steep headtube angle is specific to the tight corners and precision handling required to race at the highest level. The Bottom Bracket height is specific to crank length for better clearance on off camber course features and the very short 425mm chainstays are made for tight corners and sprint finishes. The Niner RDO Cyclocross Fork features a 15mm thru axle for best steering input.
The RLT 9 is designed as the Swiss Army Knife of off road drop bar bikes - commute on Monday, race on Saturday and make Sunday your day to wander the backroads. The hydroformed alloy frame is designed to reduce vibration and provide efficiency. The slacker headtube, lower bottom bracket and longer (435mm) chainstays combine for a stable machine perfect for long haul rides. The 1.75” tire clearance means that if you have the chops to ride drop bars on trail, you’ve got a bike that is capable. The Niner Carbon Gravel Grinder fork features QR drop outs and rack and fender mounts for maximum versatility.
