They have stopped making the ZX and now only make the One.
Everywhere seems to be out of the 25c but Starbike and Bike-Discount have them in 23 for £20 each.
Doc Blue sealant is about £6 and Stans valves are about £12.
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.
