Bikes are meant
to be used.

Niner’s mission to do all things 29” came closer to completion with the BSB 9. Short for Blood, Sweat, and Beers, the BSB was their purpose-built cyclocross rig. Available in carbon fiber only and designed around 33mm tires, the BSB is built for the needs and rigors of ‘cross. There were three versions of the BSB. The 1.0 ran from 2014-15 and featured a front thru-axle, QR rear, and post mounts for the brakes. The 1.1 was built with RDO, Race Day Optimized, carbon-fiber blend, ran from 2015-16 and had front and rear thru-axles and flat mounts.

Cyclocross touches include generous tire clearance for mud, which means 40mm wide tires can be fitted in either 700c or 650b diameters. The top tube is flattened for greater shouldering comfort, and the downtube is flattened near the bottom bracket for easy grasping when lifting the bike. The 31.8mm seatpost clamp means a lighter and stiffer seat tube.
