Product Details
The Shimano Sora ST-R3000 STI shifter set incorporates gear shifting and brake performance into one durable entry-level assembly.
Featuring reach adjustment for those with smaller hands, Super SLR braking technology and trickle down STI performance form Shimano's mid-range products, the Sora range of components are a great entry-level road product. This shifter set is compatible with Shimano 2x9 speed road drivetrains.
Technologies
New Super SLR: 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. Also for the lever, the Servowave mechanism is adopted to provide quick contact of shoe to rim and longer stroke from the initial braking effect for better control. SLR is the essential factor in the Shimano dual-pivot caliper that deliver more braking power than conventional side-pulls.
Optislick: Optislick cables feature a minimal and uniform electrically coated layer that improves cable routing efficiency and provides excellent corrosion resistance.
OT-SP41: With OT-SP41 the entire length of the outer casing is pre-lubricated with a special silicone grease for quick and precise shifting performance. OT-SP41 reduces the inner cable friction to provide quick response to operations and easy/effortless shifting. Moreover, power loss due to delay in shifting and fatigue by shifting especially when you ride on the terrain with many ups and downs as well as a long distance is also reduced.
Reach Adjust: Brake lever is equipped with a reach adjust mechanism. The distance from handlebar grip to lever can be adjusted to suit any hand size, type of riding and individual rider preferences.
DCL: DCL 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 higher standard performance than the added gearing. The shift internals borrow the robustness from our MTB technology and are so smooth and effortless that 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.
