Niner BSB 9 RDO


Pedal. Run. Push. Stumble. Fall. Get up. Do it again. You love it and you hate it but you just can’t stop. Shoulder it. Whip it through the turns. Sprint through the straightaways. Go hard. Go flat out. Claw for the starting line.

And do it on the ultimate cyclocross weapon, Niner’s updated BSB 9 RDO. You’ll give BLOOD. You’ll SWEAT. You’ll be rewarded with BEERS.

Light enough to lift quickly and easily and formed using Niner’s RDO Carbon Compaction system, the BSB rewards the rider with a frame that boasts incredible power transfer and stiffness as well as updated technology like flat mount disc brakes and access windows for Di2 routing. A 27.2mm seatpost gives just enough to take the edge off.

A steep headtube makes handling responsive. The inner triangle keeps off-the-bike comfort in check with flat areas that increase shoulder comfort. Housing gets out of the way and runs inside the frame so when you’re running, you won’t get rubbed the wrong way.

We mate this cyclocross-specific frame with our award winning RDO cyclocross fork, which provides the off-road ride quality riders want as well as updated technology including flat mount disc brakes that make installation and adjustment a breeze.
