We first saw the Flowtron dropper post at Interbike, but now we have a few more details… and it’s almost available.
This all-new dropper post is more sophisticated than their original one, but still aimed at the affordable mid-market and OEM segment. The biggest change is the remote and actuation system. The lever is longer and fits under the bar where your old front shifter was, so it fits meshes well with both SRAM and Shimano brake levers.
The cable inserts from under the post, so you feed it through from there and cut and clamp it at the lever, making installation easier. The actuation happens as the cable pulls a cam, rotating it to depress a release button under the post. This keeps all the real moving parts outside of the post, so it’s easier to keep the internals sealed and clean.
What’s most unique about the system is that you can change the spring tension on the cam, letting you fine tune the lever’s resistance and feel. Stick the end of the tension spring in one of three holes to adjust how much force need to push the lever.
The cable ends at the lever, making it easier to install. When you need to remove it, just disconnect the cable end from the cam.
Inside the shaft are three brass sliders that are user replaceable and long lasting. Using three of them supposedly minimizes rotation and play. Up top is a one-piece stanchion and head, with a 0mm setback two-bolt seat clamp that makes for easy adjustments of both angle and position.
It’ll be available in April, retail price is $TBD or €355 (including VAT). Travel lengths are 125mm (421mm length, 285mm insertion depth, 630g with remote) and 150mm (446mm length, 320mm insertion depth, 660g with remote), in both 30.9 and 31.6 diameters.
