SIR 9 27.5+ 3-Star XT Complete Mountain Bike - 2017 by Niner
One of the most versatile and smooth-riding hardtails on the market, the Niner SIR 9 27. 5+ 3-Star XT Complete Mountain Bike features the supple characteristics of Reynolds 853 steel construction paired with modernized trail geometry, 27. 5+ wheels for massive traction and rock-smoothing compliance, and 18 mounting points for bikepacking adventures.

This gives you added confidence to attack steep descents and technical trail sections previously on the edge of the old bike's comfort zone. Although it's slacker than ever, it still pedals and climbs with resounding efficiency, as Niner engineered it with a steeper 74-degree seat tube angle, which places you in an optimal pedaling position. It's no surprise the SIR 9 retains the supple ride quality of its Reynolds 853 steel construction, especially seeing its n...
