one of the jobs that was always harder than it needed to be on the XX was tyre pressures and filling I fitted these last week-
Made of solid alloy and strong as a strong thing. Available in silver as well and now I check me tyre pressures, and let them down just so I can pump them back up again I found them locally at this place-

and having discussed it with me tyre fella who fitted them, he confirmed that the wheels balanced without a problem and they'll just need re-coring at tyre change time rather than full re-valving, therefore a tad cheaper
Anyway, 250 miles later and I don't even know they're there when riding so well pleased and heartily recommended
