Bought a set of 819s years ago and just left them in the shed ( bitten by triathlon bug). Thought I should take the MTB out for a blast (to remove dust and cobwebs) so bunged a Conti Explorer (bad move) on the front, Vertical on the rear…no sealing ‘milk’ and went out… another bad move!
First rocky descent and the front pinch flatted (dinking the rim), rear was ok but needed pumping from time to time.
So, could anyone explain (without using jargon, coz I’m old and don’t have a clue what you guys are talkin about) which tyres I should go for…I’m guessing with stronger side walls?
I’ve been researching the sealant thing and it would seem I have to place sealant (I’ve bought ‘Spesialized’ version??) inside each tyre, rest it on it’s side…spin it over, spin it round ???????
What’s really worrying me it the pinch flat scenario, I mean arn’t UST supposed to end all that? I’ve lost all confidence with respect to hammering downhill… I don’t trust the UST system now.
A numbered list of ‘steps to do’ would be awesome…. Thx, & soz for it being so long a thread question 🙂
