The ReMote BarCentric is a dropper lever option for bikes with front shifters, lockout levers, or e-bike controls. The slender design of the ReMote BarCentric allows it to easily fit between the left grip and levers with four potential lever positioning options to avoid any interference with existing levers. This dropper lever has a ring shape that encompasses the handlebar, while also serving as a pivot point to provide the rider with extra leverage, making it easier to press the lever. - Compatible with left side controls including 2x shifters, suspension lockout levers, and under-bar e-bike controls - Large, smooth, sealed Enduro ball bearing that encircles the handlebar - Clean and efficient cable routing flows around disc brake levers - Adjustable reach for ideal ergonomics and controls clearance - Compatible with all cabled actuated dropper posts - Works with dropper posts that have the barrel end of the cable at the remote and those that have the barrel end at the post - Works with any mountain bike handlebar - Can be rotated to your preferred position

Wolf Tooth ReMote Light Action has a longer lever arm than the standard ReMote and is optimal for dropper posts with a harder pull or for riders that just prefer a really light actuation feel. It reduces the force to actuate a dropper by nearly a third of the standard ReMote. Based on rider feedback and tailored to work with some posts' stiffer internal springs, the ReMote Light Action is also the choice of those with thumb injuries or reduced hand strength. - Upfront cable fixing - Large diameter ball bearing - Cable-kind clamp - Low-profile, light action - Integrated cable adjust - Breakaway axle pivot - High-traction lever - Broad compatibility
