35 x 35 = Big.
The 35mm bar clamp diameter has arrived. Just as 31.6mm overtook the 25.4mm standard not too many years ago, the engineers got all engineer-y again and brought out something better. It means stronger, lighter bars. It means better bars. The Race Face Atlas 35 35mm riser bar isn't just a fat-clamp alloy bar made by the Canadian company that laughs at gravity. It's a harbinger of the next wave in cockpit evolution.
So how does a bigger bar clamp diameter make a bar both stiffer and lighter? The increased diameter of the bar at the clamp makes it inherently stronger and more resistant to deformation (twisting and bending). The strength gained by increasing the bar's diameter is disproportionately generous to the small amount of additional material used to do so, however, so now the engineers can go back and shave bar material to save more weight without compromising durability — which, in the case of the geniuses at Race Face, is vastly more durability than most riders will ever need. The result is a super wide bar that manages outrageous strength, yet weighs hardly more, if more at all, than a comparable 31.6mm bar. The 35mm-rise version of the Atlas 35 is the gravity-focused big brother of the 10mm-rise and 20mm-rise versions that are more focused on XC/trail and enduro/all-mountain riding, respectively.
The Race Face Atlas 35 35mm riser bar comes in Black and is 800mm wide with a 35mm bar clamp area, so it's only compatible with 35mm-clamp bicycle stems. The bar features an 8-degree backsweep and a 5-degree upsweep.
