I recently sold a moderately heavy SJ I bought from RubAddicition some years ago, having grown out of it, and I’d been on the hunt for a replacement ever since.
So here it is, made by RubberWerk, this is 3mm thick latex, weighing in at 10kg (over 20lbs) on its own, and add in the StudioGum helmet at another 2kg and it makes for one intense ride.
