Thanks Henry! Couldn't find any ZX in stock at Starbike and there's only one left in Bike-Discount. Stock of "One" expected at the end of August. My wheels came with valves and I still have plenty of Conti sealant left.
Just get the Ones, it's the only choice and they claim it's their quickest tyre so it can't be bad. My rear ZX will need replacing soon, in October it will be 1 year old and it's starting to get very cut up although still no punctures.
