I've been running tubeless for years on various combinations, normally NN USTs on Mavic 819 or stans Flow rims.
Got my Crest wheels yesterday, as soon as I put the UST tyres on, they seat pretty easily but then blow off the rim at 20PSI. Standard Nobbys seat with difficulty but are leaking like seives at the bead and through the sidewalls [I'm hoping more sealant will sort this, wasted lots in the UST tyres
]
Is anyone else having problems with Crest rims and Schwalbe UST tyres or is it just me?
Thanks in advance,
Andy
