Been running my general hack rigid Cannondale tubeless for a couple of years with no problems but this summer in the dry and harsh I managed to ding both rims to the point that they're no longer happy tubeless. New business cashflow means I can't really afford new rims for a couple of months so want to run the tubes with sealant as puncture season approaches.
Stans or Slime? Stan's worked great tubeless but I wonder if Slime might work better in a tube - dont know why.
Any input or experience from you guys?
Can't see how any tubeless sealant would work in a tube asa tube is very different than a tyre
it doesn't. A couple of riding friends used to swear by stans in their tubes in their fatbikes but I'm pretty sure they don't really ride anywhere they'd get punctures in the first place. I dubiously tried it on their recomendation. it didn't work.
The Slime tubes I bought for my commuter are great. But Slime has (I think) cotton flock in there to help block holes. I'm not certain if Stan's would achieve sufficient turbulence to coagulate the latex. Hence the question. (Also I have some Stan's lying around but not Slime.)
Can you just buy some new rims and swap them over, and/or bend the rims back into shape if they're not too badly dinged?
Slime. And Slime is relatively cheap and easily available.
Best of luck with the new new business.
I tried putting tubeless sealant in tubes on my touring bike as an experiment, it worked fine for small holes but as soon as I got a puncture of any size it failed to fill the hole.
<span style="font-size: 0.8rem;">Using a vulcanising patch on a tube with sealant inside doesn't work very well at all! </span>
I bought some marathon Mondial tires which are heavy but fairly puncture proof. Or use some proper slime tubes...
@ oldnpastit: I will get new rims but they are well down the order of things sadly, and they are dinged enough that I cant get a decent seal.
@ jamj1974: Sounds like Slime then. And thanks, first issue out of the new paper and it seems to be going down well. #printaintdead
Brilliant stuff eddiebaby!
OKO tractor/quad tyre sealant works well in tubes. Costs about £9 for 1.5l from agricultural supply type places.
Hmm, might try to get some OKO.
How much OkO do you use Tom (obviously depends on tyre size I guess and does it go off and require topping up ?
Very unprecise, because it's squeezed directly from the bottle (it has an applicator tube built into the lid) , but probably 80ml or so.
Used on my Genesis Vagabond, as I couldn't get the tyres up tubeless. I've pulled a few big thorns out of the tyres, so seems to work ok.
Not topped up yet, as I assume it's less likely to evaporate from inside a tube as it's more airtight than a tyre.
What about sealant in tyre and tube?
I've tried Stans in a tube and it doesn't really work, I think because 1. it congeals with the talc that tubes contain and 2. when tubes puncture they are already stretched so the hole gets instantly too big to seal and just dumps the sealant. At least that's what seemed to happen to me. Ghetto tubeless (with a split inner tube in the rim) might help this has sealed non tubeless rims for me, might help with a dinged rim.
