Again following on from my DT Swiss 27.5” wheel set purchase I always carry a couple of spare inner tubes just in case the tubeless sealant does not seal the hole, cut or tear. I have some super light Schwable inner tubes but the valve stems are not long enough now to come through the deeper section carbon rim and get a pump attached. I have tried numerous different valve extenders over the years and some have been a complete fail and some slightly better than others. To be honest I found these by mistake and did not know they even existed on the market. They work different to normal valve extensions which you screw on top of the existing inner tube valve. If you have removable cores on your presta tubes these should fit and work. You remove the valve core with a removal tool, screw in the extension with the tool provided to the part that is on the tube then screw in the inner valve core to the extension. I opted for the 30mm version so gives plenty of length now to pass through the rim and get a pump head attached. The quality looks and feels spot on. The rrp is high but as ever shop around for a deal.
