The Launch Control 4. 0 35 Handlebar is a 35 millimeter riser handlebar that comes in three high-rise options built for steep, technical terrain. Variable-thickness 2014 aluminum keeps the bar light and compliant in a 35 millimeter clamp format. What Our Gearhead(R) Experts Are Saying:"On steep technical descents, the high rise lifted my hands and kept my chest up, so my weight stayed back over the rear wheel. That upright position let me look farther down the trail."
