The Launch Control 6. 0 31. 8 Handlebar Kit is a riser handlebar kit for downhill, enduro, trail and e-bike riding, built from variable-thickness 7050 aluminum with advanced butting and refined wall profiles that add compliance. ReaFlex 6. 0 grips come in the kit, and their energy-absorbing gel dampens vibration from chatter and impacts. What Our Gearhead(R) Experts Are Saying:"On rough descents, the bars flexed just enough to take the edge off chatter. They held their shape after every hard hit, so my line stayed consistent from lap to lap."
