Had it built up and it failed whilst settling before its final check. Its bulged on the other side so its like its collapsed into the valve hole. Better happening sitting in a truing stand than when I'm tanking around Thruxton at 30 mph next weekend. Sigma have been great though it happened on Monday and they've got a courier picking it up today. Most apologetic and full refund coming.
Looks like i won't be using my new Knight 95 up front next weekend after all
