So update on the giant contact switch. It looks really nice, the overall impression is that its simple but good build quality. The lever isnt a design I would have chosen but its easy to use, light action and better than the reverb one. Post has slight lateral play, maybe more than a reverb but i cant feel it when riding. The option to swap the cable mounting from top to bottom is brilliant. The whole mechanism is in a cartridge and it looks like the rest will be easy to take apart and clean. Post stays put if you happen to lift the bike by the seat. 150 mm is great for getting the post totally out of the way but does leave a lot of cable loop when externally mounted. Very impressed overall, will have to see how it lasts. Im probably going to sell my other reverb to try and fund another one of these for my second bike.
