I accidentally(*) bought a non-tubeless-ready version of the Specialized Roubaix Pro road tyre.
What are people's thoughts on the advisability of running this tubeless on one of those Ultegra tubeless rims? It mounts up just fine and holds air.
Thanks.
(*) They assured me it was tubeless-ready in the LBS, but it doesn't actually say that anywhere on the casing, so I suspect it's a non-TLR tyre. I can't really take it back now that it's covered in white gloop though.
I wouldn't. Not if it's a std clincher.
Anything below 50psi will probably be fine but above that it's an experiment, with your tooth count as the empirical measure of success.
I wouldn't, road tubeless has a carbon fibre bead to deal with 100psi, normal tyres don't.
Advice from my lbs is that the crucial component in a tubeless road set up is a tubeless ready tyre
I wouldn't chance it with road tyres, whether it stays up now or not.
The bead stretches and who knows when it will go KaBOOM???
Don't do it.
OK, I've fitted a tubeless tyre.
So, next question, the rear has a hole from a monster thorn. It's sealed, but it's quite bulgy (but holding at around 70psi on a 25mm tyre).
Leave it, put in one of those sticky worm things, patch it from the inside, or bin it?
I put some duct tape on the inside and super-glued the cut from the outside. Apart from now having an annoying layer of superglue on my finger, it seems pretty convincing.
I've patched them on the inside in the past, and they've been fine.
I think the roubaix pro is tubeless ready - at least I'm not aware that they make two versions
(Edit: err, yeah, they do seem to make 2 - sorry)
check the box carefully, are you sure it doesn't say 2BR or anything like that ?
I bought two tyres,, one for a different bike and the other one does have different markings. But that's a 30mm and won't ever fit this bike.
Flexible glue on the outside, I fixed a tubular with Loctite 480 on the outside when sealant alone didn’t want to hold.
It got me through the rest of my season without trouble.
Not at road pressures. I run non tubeless cx pros on stans crest fine at about 20-30 psi. I also blew off a non tubeless continental on a non tubeless kayrium at about 85 psi (in testing off a bike, not riding). I’ve run tubeless road on non tubeless rims fine at road pressures. But I would not do the reverse.
