What Our Gearhead® Experts Are Saying:
“The Flowtron is simple, compact, and customizable. The adjustable spring tension lets you dial in the lever feel exactly how you like it, whether you want feather-light actuation or a firmer push.”

Its forged, shifter-style remote and industry-first adjustable actuator spring allow you to fine-tune lever resistance for personalized control. A compact design with integrated stanchion head reduces insertion depth and keeps things sleek, while the sealed alloy cartridge ensures lasting durability. Available in 125mm, 150mm, and 175mm travel options, the Flowtron gives you the range you need for steep descents and all-day epics alike. Whether you’re rallying enduro lines, threading tight switchbacks, or cruising flow trails, the Flowtron keeps your saddle exactly where you want it every time.
