Review on Tranz-X Jump Seat: Cable-Less Dropper Post - The Ultimate Riding Companion by Oso Mears

I have an older Salsa Beargrease with a 27.2 seatpost. I didn't really want to mess with external cables and appreciated the easy clean install. I was concerned about the potential issues of having to grab the handlebars with one hand to adjust the seat, but at fat bike speeds, controlling the underseat droppers wasn't a big deal. It is more difficult to operate when using the poggy on the handlebars. So far the campaign has been very positive. So far very satisfied.
