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.
