How often do we all top up our tubeless setups? All new fluid or just throw a bit more in?

I usually forget. And get punctures that don’t seal every 6 months or so. So I’d guess I need to top up more frequently than that.

Seriously, when I asked this before, the consensus was to give the wheel a shake. If you can’t hear fluid sloshing about, add some more.

I’ve been getting lax at keeping them topped up. Today I sliced a tyre on some freshwater mussel shells and it wouldn’t seal even with plenty of liquid inside.

When the tyre came off to put a tube in, the liquid inside was very watery and there was one of those big rubber monster things. Basically, the liquid had lost all its latex.

Every 3 months or so

My bike sits next to a radiator in the garage and that dries the stuff up pretty quickly 🙁

I just add a little when I swap tyres, so I never really have to worry about remembering to top it up.

A radiator? In the garage??? How the other half live! 😉

Every few months.

3-4 months

Unless you’ve had a noticeable puncture (i.e. tyre went a bit soft or there’s evidence of sealant) then 3-4 months – just throw a fresh scoop or two in.

I never top it up as a routine thing – would only do so if I started to get punctures or if the tyres were deflating on standing overnight. I guess with changing tyres the odd time in the year this cycles new latex in.

You can definitely go a long time without doing owt – assuming non-thorny trails, decent set-up, go 6 months easy and the tyres will still have a decent seal.
