With comfortable hoods and lightweight aluminum levers, SRAM's 500 Single Speed Brake Levers are the perfect choice for your non-geared bike. Even if...
While these levers look sweet they have a miserable fit. These are just gutted Apex levers which leaves a huge gap between the brake lever and hood where the shift lever should be. Besides this gap being overall annoying while riding in the hoods I've notice that my index finger gets pinched in this gap while carrying my bike over barriers (which is the last thing I want to think about). Hold off on these levers until SRAM designs specific single speed levers.
