Stratos AL 5.0 is the mountain bike for 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 5.0 uses the same frame as the AL 1.0. Based on the groundbreaking Stratos CF race machine, but adapted to offer a more value focused, mild mannered bike for the everyday rider. New to mountain biking, or first full suspension bike; trails, XC or marathon, the Stratos AL 5.0 is designed to take care of business.
