I've had a search round my local bike shops - in the last couple of months there have been 2 thunderbird sports and 3 thunderbirds sold by the dealers (including mine). Unfortunately, there don't seem to be any left now.
The availablility in central scotland of triples seems to be OK, there tends to be a glut of them and then none so I'll have to wait and hope.
My insurance will pay out (as the evidence is irrefutable - we have the B******s on CCTV taking the bike) but I have a £500 excess and loose my no claims so between everything I recon I will be about £1000 out of pocket between the excess, my expenses (bus travel etc) and the increase in insurance. Also the insurance won't pay out for 28 days so I'm stuck with buses until then.
I am majorly pissed off!
