his is a pair of Shimano 105 ST-5800 Dual Control Levers. SLR stands for SHIMANO Linear Response. The New Super SLR design makes use of a friction-reducing mechanism in the caliper, lever and cable that improve response and modulation. 105 now gains the light yet positive shift action found in Dura-Ace and Ultegra levers. The compact shape is also borrowed from the the levers of Shimano's more high end groupsets. The lever has reach adjustability to accommodate different hand sizes via a 10mm screw-type reach adjustment. Premium polymer coated cables are now standard as well. This 11 speed version is compatible with it's 11 speed Shimano family in Dura-Ace and Ultegra.
