reTyre - zip-on tyre system

I’ve posted earlier about reTyre who custom made a studded skin for my 36’er: Studded tyre for 36'er - possible solution?

reTyre have developed a new system were the zipper is sewed on to the tyre (like they did for me), and you can switch between asphalt, terrain or studded tyre in a minute. The retyre comes in the sizes 26, 27.5 and 29. The tyre width with the skin is 2.1-2.25.

If anyone’s interested, there’s a kickstarter campaign going on right now:
