[Closed] Using slime/sludge in tubes?

I've just started doing it - Schwalbe tubes with removeable cores and Joe's sealant (about 60ml per tube)

I made a point of making it tough for the tubes by using narrow tubes (1.75" max by size) in 29er wheels with 2.1 and 2.2 tyres. No flats so far.

I found getting the liquid in could be awkward - used a syringe and made sure I shook up the sealant before injecting it - two were easy, the third kept gumming up so I had to clear it a couple of times with a paperclip but it seems fine now.

These are the ones I used

Great idea, all of my m8's & myself do it.
No its not infallible but better than nowt, or paying lots of money to go tubeless (unless you need/want to run low pressure).
Dr Sludge/Slime all the same, both work equally well.

As clubber says, the issue is that the valves tend to gum up over time, so removable cores (so you can clean them) are the way ahead.

For me it's not really about the cost of tubeless it's just the hassle if you want to change tyres which I do. I'd certainly try tubeless otherwise.

I do this, but I expect most don't due to the weight penalty. It works.

Works for me, mostly. First time round I used aftermarket Slime on the kid's bikes and Dr Sludge tubes on mine. Schrader valves all round though.

Has failed twice:
1) a thorn got in the tyre and the top broke off, so the point kept reopening the hole. Had to take the tyre off and find the pointy bit.
2) the fluid dried/got used up - top ups required every so often.

More thorns here than you can imagine ([url= http://en.wikipedia.org/wiki/Tribulus_terrestris ]T. terrestris[/url] and [url= http://en.wikipedia.org/wiki/Acacia_erioloba ]A. erioloba[/url]).

I read a review somewhere complaining that sludge/slime put the wheel out of balance. This is true if the bike has been standing as the fluid pools at the bottom of the tyre - needs a few revolutions to get spread out again. (Preaching to the choir on this one, I suspect).

Due to a lack of Stan's/Joe's in this part of the world I went to a tyre dealer and used their no-name sealant - less than a tenner for 2 litres. Injected into the tubes with a 5mm-nozzled syringe and piece of plastic tube after removing the valve cores.

Tails: Better weight than wait.
