Micro Shift R9 9 Speed Road Levers Micro Shift road levers are 100 percent compatible with Shimano and SRAM rear derailleurs and shifters, and also with Micro Shift shifters and derailleurs. They are similar to shifters from the companies mentioned above, but allow the rider to shift from the drops, unlike some other shifters. With this Micro Shift design, the shifting functions are separate from the brake lever, with the brake lever not moving during the shifting process. Micro Shift R9 9 Speed Road Levers are available for 2x9 and 3x9 drivetrains, to accommodate two or three front rings. Get modern shifter functionality at a very wallet-friendly price. Stainless shift cables included. Note that these shifters do not have concealed cables; the shifting cables are routed externally from the levers.
