They’ve been around for a few years but until recently have been a fairly niche product prone to failure. The target market is mountain bike racers who want the saddle down and out of the way for the rough stuff, then up at the optimum height for pedalling on the flat. Adjustable seatposts enable the saddle height to be changed ‘on the fly’ without stopping.
At last, finally out on the trike again thanks to Schwalbe’s Winter Marathon tyres. I imagine many of us are going stir crazy in this weather, waiting for a thaw to avoid injury. Well, I couldn’t wait any longer!
