After heaps of flats last year I finally gave in and installed Slime tyres with presta valves on my roady. For 3 months now, no more flats.
Tonight, though, when I 'released' the presta valve (ie letting some air escape to unblock the valve) instead of air escaping, a whole bunch of Slime came out! Cleaned that up pretty quick, but now my valve is blocked. How do I unblock the valve without getting slime everywhere? When I press the core in (as if to release more air), it fully presses in but no slime or air is escaping now. If I try to pump more in (as if to force the slime back into the tube) it gets nowhere. Tyres are probably still inflated to about 95-100psi (normally aim for 115-120psi).
Has anyone had/solved this problem before?
Remove the valve stem give it a clean replace Have valve at top when doing this
better off with stan's
PS you know you can not patch a tube with slime
and give it a top up too
Cheers Tim - how do I go about removing the valve stem? Do I need a special tool?
Aware of not being able to patch slime tubes, but they have sure saved me a lot of punctures :)
Car ones you do about $4 at LBS or BMCR anyway
French one spoke key if they are two part ones
Can't run tubeless
No good for side wall flats
Dose not like water
Slammin and I always go without the tubes on the MTB's. I think that most current road rims are also built to go tubeless, just that it hasn't taken on because roadies are such weight weenies and stronger sidewalls mean more weight. Higher pressures also probably mean that to seal a hole is probably not as effective as lower pressure high volume MTB tyres. Thought about putting Stans into the road tubes, but haven't implemented plan as yet. Keeping tyres full of air and changed regularly (touch wood) no flats lately.
Hutchinson system for road is pretty expensive, too.
