Places lever in optimal position left vacant by the lack of front shifters on 1x setups. Made from forged and machined 6061-T6 Aluminum for high strength and light weight. Lever pivots on precision bearings for smooth action and durability. 2 mounting positions for ideal placement for each user. Increased leverage ratio for reduced actuation force over universal lever. Textured non-slip thumb pad for not slipping thumbs. Will actuate Race Face and Easton dropper posts and many other cable operated posts (11mm of cable pull max). High quality cable tension adjuster to dial in post operation perfectly. Quick disconnect from handlebar for post cleaning/adjustments/service while leaving clamp fixed to the bar where you like it.
