This Specialized Enduro Comp Mountain Bike is a high-performance machine ready to tackle any terrain. With a full suspension system, this bike can handle the toughest trails with ease and still leave you with untapped suspension travel. This bike also comes with tubeless tires and Cush Core insert of the rear wheel, a dropper seat, and suspension lock-out. The frame is made of carbon fiber for lightweight and durability. Given the S4 size (S1 being the smallest and S5 the largest), the bike generally fits riders who are between approximately 5'-10" and 6'-3" tall. This sizing recommendation can vary slightly depending on individual body proportions and personal preferences for bike fit. Personally, I feel the larger size complements riding conditions for which this bike is built ... DOWNHILL BIKE PARKS! The matte black raw carbon frame is definitely a head turner.
