Details

Niner’s SIR 9 is a savvy reminder why every great bicycle comes down to three things: good ideas, good workmanship, and good materials. The SIR 9 combines these qualities in a soulful ride that ensures every ride is a great day on your mountain bike. Niner worked with Reynolds to produce a 853 DZB (Double-Zone Butting) steel tubeset that uses multiple wall thicknesses and a Niner-specific down tube bend to maximize strength and torsional rigidity at the head tube-down tube intersection while maintaining adequate clearance between the down tube and front tire, a tricky balance for 29ers often requiring the addition of gussets (and weight). Niner’s Biocentric II eccentric bottom bracket offers a dramatic range of adjustability and allows for clean, rock-solid single-speed setups, manual multi-gear swaps without chain length or brake adjustments, and bottom bracket position adjustability for fine-tuning your geometry. The tapered head tube is stiff and strong to keep the front end tracking true when the trail throws everything it has at you. The rear through-axle provides great power transfer and responsive handling.

The SIR 9 2-Star GX1 will fast become your always-reliable, ready-for-anything trail rig. RockShox has you covered with a Reba RL Solo Air fork that makes silk ribbon of rock-strewn trails. SRAM’s GX1 drivetrain puts a wide range of intelligently-spaced gears at your fingertips, giving you the range you need in a streamlined 1 x 11-speed package that keeps your legs pumping at the sweet spot. Legendary Maxxis Ikon traction keeps you pinned through berms, while powerful SRAM DB5 brakes offer controlled modulation so you can scrub speed into that next switchback.
