Shifter Shimano SORA ST-R3030 3-speed

When ranking Shimano’s road groupsets for beginners, or better said in the middle class sector, Sora was developed for fitness and hobby orientated riders. With its durability as well as the attractive price, ambitious road cyclists also use it on winter training bikes and commuters for the ride to work the whole year around. Beginners and experienced riders using the 3-speed Sora R3000 have the advantage of numerous features and technologies that were first introduced in the top groupsets of Shimano a few years ago.Gearing: 3-speed (LEFT)Type: dual control (STI)Shift Lever: mechanicalBrake Lever: mechanicalLever Material: aluminium, paintedHandlebar Diameter: 23.8 – 24.2 mmShifter Cable: stainless steel (Optislick)Recommended Cable Housing: OT-SP41Reach Adjust: yes (bolt)Gear Indicator: noTechnology: New Super SLR, DCLTechnology:New Super SLRSLR stands for Shimano Linear Response. The New Super SLR design makes use of a friction-reducing mechanism in the calliper, lever and cable that improve response and modulation.Also for the lever, the Servo Wave mechanism had been adopted to provide quick contact between shoe and rim as well as longer stroke before the initial braking effect for better control.SRL is the essential factor in the Shimano Dual-Pivot calliper that delivers more braking power than conventional side pull brakes.DCLDCL stands for dual control lever. It has brake and shifting functions in the system and enables easy operation. Ergonomic innovation is probably more critical to the high standard performance than the added gearing. The shift internals borrow the robustness from the MTB technology and are so smooth, that effortless one finger shifts front and rear are possible. Indeed, shifting is the ultimate act of Shimano total integration, and simply has to be experienced to be understood.Art. Nr.: ESTR3030LIA
