I set my wheels up tubeless at least 6 months ago and these days i cant really hear fluid swishing about. Does this mean its likely to have dried up thus no longer providing protection? How often do you check?
I shake it, if I cant hear it sloshing its time to top up.
I live somewhere pretty cold and 6 months is the max i've managed.
3months. 6 might be dry. Depends on the tyre though. Conti or spesh - definitely dry!
Do them all every three months, valve core out and top up with an old stans bottle, core back in, re inflate and spin wheel. Takes us about a hour to do nine bikes. All done at the same time so we don't miss one. Even if we have had to replace a tyre in between it still gets done at the same time.
Thanks. I guess i will be adding fluid this weekend then.
I have spesh tyres by the way, does the make have an affect on the fluid?
How long till valve cores become blocked with fluid? Mine have been playing up a bit but i would be surprised if thats it after just 6 months surely.
when the tyre goes down. I normally check tyre pressure before every ride and some bikes hang around not doing anything for weeks at a time, usually easy to spot when one has "gone dry"
my valve cores have been ok, have heard reviewers mention procore "clever" valves getting a bit gunked up, but remove bit of hot water and refit and they're fine (easier to inflate too so remove/refit while messy should be quick)
Very organised Tracey. I had a bit of paper with dates on. Except I've now lost it so down to the 'give-it-a-shake-and-listen' method.
Spesh are quite porous so you lose the liquid part of the sealant more quickly through the sidewalls. Vittoria are the opposite.
Valve cores - remove and clean them and if too far gone, then a multipack of cores is quite cheap.
Pretty much never, yet to have a puncture that sealant has any effect on (if I rode somewhere with loads of thorns this might differ)
haven't touched mine since Aug last year and can still hear fluid sloshing about. Didn't actually realise it needed changing so often...
probably a stupid question, but where does the sealant go ? does it evaporate, solidify, or what ? Just imagining topping up every few months and the inside of the tyre ending up with a thick layer of solid sealant getting heavier each time !
Can you tell I don't have tubeless setup yet ? 🙂 Losing my virginity on it this weekend probably 🙂
tyre ending up with a thick layer of solid sealant getting heavier each time
Well it has a % of solids and the rest is water and some other liquids which yes, as you point out evaporate.
If there is no obvious weep on the outside then yes it is likely that by topping up all you are going is adding more weight. Would best to pop the tyre off and clean out the old stuff IMO.
I am wondering whether to go back to tubes due to the faff of cleaning out old sealant and topping up on bikes I dont use as much
Seriously, how much weight do you think its going to add and at what weight increase do you think you might actually notice it?
Milkit have a neat solution to this very problem amongst others.

It's also offset by the rubber wearing off the tyre 😉
Where does the sealant go? You say...

Not my strangly shaped hand or picture
I usually pop one bead and remove any Stanimals after 6 months or so. Then just top up with fresh spunk.
Looking forward to all these experiences that I don't have with tubes ! 😀
. So when you top up, how much fluid goes in ? I have just set mine up so all new to this. I used about 90ml for initial setup as per the instructions on the Stans bottle (650b Nobby Nic 2.25's)valve core out and top up with an old stans bottle, core back in, re inflate and spin wheel.
I change mine when/if I change tyres. It hasn't made any difference to the rate I get punctures (i.e. never)
Use an old Stan's 2oz bottle which I top up from a big bottle. The top is designed to fit in the valve stem and the bottle is easily squeezable.
^^ thanks
When we put the Stan's in the tyre for the first time we use the plastic top off a washing powder liquid bottle as they have graduations on the side usually up to 100 ml. Saves a lot of messing about
Yeah, I did same !
New Giant wheels were easy, just need to work out what I need now to do the older XM719's with Puragtorys on the HT...
