At 785mm wide, Race Face's Atlas 1/2in Riser Handlebar's been designed with the gravity rider in mind. And to fulfill the strength requirements this sect demands, the Atlas is constructed from cold-drawn, seamless 7050-T76 aluminum with internal butting at the clamp zone. For excellent ergonomics and control, Race Face gives the Atlas an eight-degree rearward sweep and four-degree upward, which places the wrists in a neutral position. This allows riders to naturally maneuver the bike in the air and on land along multiple axes. The Race Face Atlas 1/2in Riser Handlebar comes in an anodized, durable Black finish, and it has a 31. 8mm clamp diameter.
