update on the tubeless tyres
deflated them today , took tubes out , fitted valve , blew up with no goo in them - and they went up!!
let them down again and put stuff in the valve , blew up , no mess , no swearing and they are holding
if i was to try again i would definitely try a dry run first to seat them then worry about latex after
now just for some dry weather to try them out for a few miles to see if i will put them on the 'trip ' bike
you wouldn't believe how happy i was when i heard them pinging into place
