We rode the new Schwalbe Procore dual chamber system some weeks ago during the Scott 2015 press presentation. As we said in that article, we think this is going to be a game changer (read why). Today at Eurobike Schwalbe unveiled all the details, including a new single valve used to inflate both air chambers. No need to drill a hole in the rim anymore.
Watch the video for all information. The weight is 200 grams each, the price is going to be 179 Euro for a set.
