SRAM’s original Red crankset was made of carbon, but it was built with a foam core that prevented it from being as light as it could be. That’s been remedied this time around, making the new Red GXP Crankset one of the lightest, strongest, and stiffest cranksets out there. Although the weight difference isn’t huge, every gram counts when you’re trying to beat the peloton to the top of the pass or put inches between you and your closest sprint competition. SRAM also boosted the diameter of the crank arms and spider, but reduced the spider arms from five to four to save weight even while strength was increased. You can’t beat Red’s power transfer, nor can you beat the smoothness of the shifting–SRAM’s Exogram technology lowers the weight further while X-GlideR technology make shifting virtually perfect, so you can dial in the perfect gear at a moment’s notice. That’s how you get to the finish line first.
