Top: The so-called Vent Valve allows the post to be vented without tools at the touch of a button, as if a lorry were, chhhhh, blowing its compressed air tanks free. The clamping head has also been redesigned. One screw clamps the saddle, another adjusts the angle, which works really well in practice. But the real highlight is that it is controlled wirelessly and does not need any cables. This means I can simply insert the seat post into the frame, screw the remote to the handlebars and couple the components at the touch of a button.
Zack, off you go on the trail. The controller is as easy to press as my computer keyboard and controls the servomotor without any delay. As long as I press the controller, the lift descends noticeably smoothly into the basement. Intermediate positions can be found even more precisely than with a classic Tele support, and the extension speed is also perfect. It doesn't matter that the speed is no longer adjustable. The charge status of the battery can be checked both on the support and via the app. Depending on use, a charge lasts around 40 hours. The battery was fully charged again after just under an hour. By the way: You don't have to switch on the Reverb AXS. A sensor starts the seatpost as soon as the bike is moved. The new Reverb AXS is available with 100 to 170 millimetres of travel.
