I-SPEC II: Simple structure with narrow brake lever clamp band. More space on handle bar and cleaner appearance. 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 maximally 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. 8 color options are also available for outer casing to meet many requests. Rapidfire Plus: Mountain bikers have used Rapidfire Plus since 1985. Rapidfire Plus is still a winning choice from a wide range of riders from XC racers to freeriders. Rapidfire Plus is suited to quick shifting, giving riders the ability to downshift three gears in one stroke. Rapidfire Plus shifters from DEORE to XTR all feature 2Way-Release, which means release shifts by pull of the index finger or push of the thumb. 2-Way Release: The Rapidfire Plus shifter release lever is commonly called a trigger because it is operated like a pistol, by pulling toward the grip. The release lever of Rapidfire Plus shifters from Shimano Alivio to XTR can be operated in this same manner but adds the ability to activate a release shift by pushing with the thumb. Instant Release: Instant Release shifting replaces the two-stage click and release shifting you are familiar with. Instant Release shifting releases cable as soon the lever is activated, resulting in the quickest possible gear changes. Whether it is an upshift with a top normal rear derailleur or a downshift with low normal rear derailleur a quicker shift is always a better shift.A 2-year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).Buy Shimano Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
