From exploring gravel roads to checking out those long mountain passes, Opus's Spark 2 loves to take you anyplace you want to go. Its triple-butted aluminum frame is responsive, nimble, and makes short work of whatever surface you're on. The low bottom bracket, wide tire clearance, and long chain stays ensure stability and comfort all day long. Shimano Tiagra drivetrain components and FSA crank equip you with smooth shifting and all the gears you need. TRP HY/RD disc brakes handle braking duties with finesse and control, while Alex wheels with wide multi-surface tires inspire confidence on rough pavement and gravel roads.
