The Shimano CUES SL-U8000 shifter is designed for 11-speed shifting and is compatible only with LINKGLIDE.
LINKGLIDE delivers smooth shifting and pedaling performance designed to last. LINKGLIDE supports stress-free riding and ownership across evolving bike types and riding styles. It is an exceptionally durable drivetrain designed to withstand persistent daily wear and provide enduring shifting and pedaling performance for multi-purpose bikes and high-torque e-bikes. The robustly engineered cassette shifts smoothly up and down the gears while significantly reducing drivetrain wear. Its shifting gate design is optimized, and the robust cassette teeth resist damage when shifting and pedaling under high torque.
RAPIDFIRE PLUS has been used by mountain bikers since 1985 and remains a suitable choice for a wide range of riders, from XC racers to freeriders. RAPIDFIRE Plus is designed for quick shifting and lets riders downshift three gears in one stroke. All RAPIDFIRE Plus shifters from DEORE to XTR feature 2-WAY RELEASE, which allows release shifts by pulling with the index finger or pushing with the thumb.
INSTANT RELEASE replaces the familiar two-stage click-and-release shifting. The cable is released as soon as the lever is activated, resulting in the quickest possible gear changes. A quicker shift is always better, whether shifting up with a Top Normal rear derailleur or down with a Low Normal rear derailleur.
2-WAY RELEASE The release lever on a RAPIDFIRE Plus shifter is commonly called a trigger because it is operated by pulling it toward the grip, like a pistol trigger. The release lever on RAPIDFIRE Plus shifters from ALIVIO to XTR can be operated this way, and can also be activated by pushing it with the thumb.
