Stratos AL 2.0 is the mountain bike every recreational rider can enjoy. Silverback’s POP geometry makes it a strong climber and a balanced confident descender. The linkage driven asymmetric single pivot suspension is tuned for optimal small bump sensitivity and big hit compliance without power delivery penalties. The suspension curve is designed to offer full use of available travel. The Stratos AL 2.0 is based on the groundbreaking Stratos CF race machine, but geometry is adapted to offer a more capable bike for the everyday rider. The component highlights for the Stratos AL 2.0 includes a 12 speed SRAM NX drivetrain and a Rockshox Reba 120mm fork. XC, marathon or trails, the versatile Stratos AL 2.0 is the right mountain bike at the right price!
