The new Deore - "Rider Tuned" for every style of cycling.
The Deore is a group that consistently continues the "Rider Tuned" principle and is ideally suitable for various types of bikes and riding styles. Whether for cross country or trail, on hardtail, on 29er, 650B or on fullies: The Deore offers all options to meet every requirement.
The Shimano Deore SL-M610 Rapidfire Plus shifters are optimized for 10-speed Dyna-Sys systems. For best cycling comfort they offer Shimano's 2-Way-Release technology and easily readable optical gear displays. 2-Way Release allows different riding styles or shifting (indexfinger or thumb) from various riding positions. The upper lever still performs the same function, but now it swings both ways. Pull it with your finger or push it with your thumb - you choose. The changed lever design improves the shifting ergonomics and offers more feedback to the rider.
The 3x/2x manual mode converter allows you to manually change the left hand unit to be used with both double and triple cranks.
Optimized for derailleurs with conventional spring alignment.
