The Jagwire LEX-SL 3mm Cable Kit (commonly known as the Pro Dropper Kit) is a game-changing upgrade for any mountain, gravel, or enduro bike running a cable-actuated dropper seatpost. Standard gear shift housing is thick, stiff, and notoriously difficult to guide through the sharp, tight bends found inside modern bicycle frames, often causing sticky remote levers and sluggish post returns. Jagwire solves this problem entirely by shrinking the outer housing diameter to a mere 3.0mm. This reduced profile dramatically increases flexibility, making internal routing through bottom bracket shells and tight ports a breeze, while significantly reducing friction.
Inside the housing sits Jagwire's premium 0.8mm Pro Polished stainless steel inner cable. Engineered specifically for dropper post remotes, this thinner-than-standard inner wire interfaces flawlessly with actuator arms and compact handlebar levers to deliver an incredibly light, crisp tactile feel. Combined with a factory-lubricated Slick-Lube internal liner, the LEX-SL kit eliminates cable drag and keeps your dropper operating smoothly in the muddiest Australian riding conditions. Complete with open alloy end caps, heat-shrink shims, and a cable tip, this comprehensive kit contains everything needed to completely refresh your dropper post actuation.
Ultra-Thin 3.0mm Outer Housing: Shrunk down from standard 4.0mm gear housing to maximize flexibility and reduce weight within crowded internal frame ports.
Dropper-Specific 0.8mm Inner Wire: A thinner Pro Polished stainless steel cable that slides effortlessly around tight bends with minimal lever resistance.
Slick-Lube Internal Liner: Pre-lubricated liner ensures a highly fluid, friction-free performance that resists grease dry-out and contamination.
Linear-Strand LEX Construction: Delivers compressionless performance for immediate, instantaneous dropper post reaction when hitting the remote lever.
Comprehensive Fitting Spares: Includes open alloy end caps, heat-shrink shims, and a cable tip to provide a professional, workshop-clean installation.

Fight Internal Routing Nightmares: Perfect if your bike frame has tight, awkward internal channels that make standard 4.0mm gear cables lock up or bind.
Want a Lighter Lever Feel: Ideal for riders who want to eliminate thumb strain and enjoy an instant, buttery-smooth dropper activation.
Own a Ultra-Compact Remote: The specialized 0.8mm wire is perfect for modern levers that feature small cable clamping pathways.
Ride in Harsh, Dusty Conditions: Excellent for Australian trail riders who need a heavily sealed, lubricated system that keeps out grit and grime.
Appreciate a Complete Kit: Great if you want a true "one-and-done" upgrade pack with all the premium alloy ferules and heat-shrink bits included.
Need a Standard Gear Shift Cable: This kit is exclusively built for dropper posts and suspension remote lockouts; the 0.8mm wire will snap under standard derailleur tension.
Run an Electronic Dropper Post: Completely redundant if you are running a wireless electronic system like a SRAM AXS RockShox Reverb.
Using a Hydraulic Dropper: Incompatible with fluid-actuated systems like older generation RockShox Reverb posts that require hydraulic bleeding.
Because the 0.8mm inner wire is noticeably thinner than a traditional gear cable, you must take extra care when clamping it at the actuator arm or remote lever end. Avoid over-torquing the cable pinch bolt, as doing so can flatten or fray the thin strands prematurely. For a factory-clean finish, utilize the included heat-shrink shims over the cut cable end before crimping on the tip. This seals the wire completely, prevents unravelling, and makes future maintenance and tension adjustments a breeze!
