Our SRAM-compatible Hudz address the slippery rounded profiles on the top and bottom of the SRAM Double Tap levers and square-off the profile to both sides of the bottom of the lever body as well as the top lateral side (i.e. the right side on the right-hand lever) to provide more grip and reduce hand and arm fatigue. Our Original Enhancement Brake Hoods started it all. The goal was simple - to mimic the firmness and texture of popular OE hoods while creating a more ergonomic shape. And since we were making these new hoods, we figured that offering them in a range of colors would be a good idea as well. SoftGrip - the name pretty much says it all - these are 25% softer and provide 80% more grip than our Original Enhancement Brake Hoods. They can serve as a way to help tame the pounding of rough roads or as the ultimate enhancement for a cyclocross bike. Lever/System Compatibility: For use with 10-speed SRAM Double Tap systems including Rival, Force and Red. OE Replacement Part Number: 11 7915 000 000.
