Niner revisited the world of Blood, Sweat, and Beers, namesake of the BSB 9 RDO, to update the race-ready frameset for the upcoming cyclocross season. The already stiff, light frame got stronger with the addition of 12 x 142mm rear thru axle; but otherwise, Niner was so pleased with the functionality of the design that it didn't feel the need to make any other changes to it — aside from some new graphics, of course.
The BSB 9 RDO is built for the rowdy, obstacle-embracing 'cross set, so it's expected to exhibit stiffness and strength on difficult terrain while remaining light. Niner achieved this balance by using its Carbon Compaction System to mold the frame, fine-tuning the placement of carbon and eliminating any material that didn't directly contribute to the frame's sharp handling or lateral stiffness.
The process involves laying-up the carbon around rigid foam molds, which Niner claims provide a more consistent shape than traditional bladder molds. At the end of the process, the inside of the tubes is as flawless as the outside, and the BSB 9 RDO is lighter than comparable frames. The 530g, thru-axle fork is also fully carbon, and it borrows much of its design from the rigid fork on Niner's Air 9 RDO hardtail with a slightly flatter profile to better adapt it to cyclocross.
Don't deny the BSB 9 RDO the pleasure of 'cross racing. With its steep head and seat tube angles and the pedal clearance of a high bottom bracket, the frame was made for it. Niner's roots in mountain bikes mean it's no surprise that the frame was built for disc brakes that offer plenty of clearance during tight cornering, and it's also compatible with internally routed mechanical or electronic drivetrains.
The frame is finished with a playful nod to cyclocross's often irreverent attitude: When you shoulder the BSB 9 to navigate a steep run-up, astute fellow racers behind you will get some encouragement from Niner's signature admonition to "Pedal, damn it," which is inscribed on the bottom bracket.
