The Race Face Atlas cranks are continuing to utilize the same proprietary OPTIM-AL alloy hese cranks have been updated to use our EXI, external ISIS interface.
In the process we have been able to sculpt away between 31 and 81grams depending on configuration from our first generation offering without sacrificing any strength, producing our lightest big hit, freeride cranks ever! 822g (165x36T, w 68/73 + BB) 842g (165x36T, w83 + BB)
