Norco Bicycles’ 2018 Sight A3 Mountain Bike is savvy all-mountain aluminum bike with a RockShox Revelation RC fork (140-150mm travel), a RockShox Deluxe RT rear shock with absorbent DebonAir and efficient Solo Air technologies, versatile tubeless ready WTB STP i29 wheels, and aggressive, all-weather Maxxis Forekaster 2.35 tires.
