Shimano Deore SL-M610-R 10 Speed Gear Shifter - Black, Black
  • £9.99
  • RRP £29.99
  • Saving you £67

Shimano Deore SL-M610-R 10 Speed Gear ShifterThe Shimano Deore SL-M610-R Shifter is ideal for intense mountain bike (MTB) adventures. This mountain bike gear shifter gives you smooth and reliable gear changes on the roughest of rides.Whether you're riding with your friends after work or exploring new trails on your own, this shifter is engineered for performance. It features a Rapidfire Plus lever which is great for riders who want fast shifting as it allows them to shift down up to three gears in one single stroke. Shimano has also kitted out this version with 2-way release technology, which means that the shifter cable is released by pulling with the index finger or pressing with the thumb. Features: Use: MTB SL Cable Adjust: Yes Recommended SL Outer Casing: OT-SP41 (available separately) Release Function: 2-way release Shifter Type: Rapidfire Plus Drivetrain Speed: Front: 2/3-Speed; Rear: 10-Speed Bar MountTechnologies: Rapidfire Plus: Rapidfire Plus has been used by mountain bikers since 1985. Rapidfire Plus is still the first choice for a wide range of riding groups, from Cross Country racers to freeriders and downhillers. Rapidfire Plus is suitable for fast shifting. The rider can shift down up to three gears with one shift stroke. 2-Way Release: All newer Rapidfire Plus shifters are equipped with 2-way release (release in two directions). This means that the shifter cable is released by pulling with the index finger or pressing with the thumb. SP41: With OT-SP41 the entire length of the outer casing (available separately) 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 colour options are also available for outer casing to meet many requests. Dyna-Sys: SHIMANO's next generation 10-speed MTB drivetrain. SHIMANO presents the drivetrain technology for mountain bikes: DYNA-SYS. This revolutionary technology uses a 10-speed cassette, but that is not the only feature of this system. Highlight is a completely redesigned drivetrain that creates real added benefits for the rider. It's not only an extra gear…It's about closer gear ratios for a smoother shifting performance and improved power transfer. It's about riding optimized gear combinations that improve efficiency and durability. It's all about performance: DYNA-SYS offers a more stable drivetrain for any type of rider!Buy Shimano Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
