going tubeless

I searched for some info on road tubeless but couldn't see it if it was there!

So..... I ordered some fulcrum 1s and they're arriving later this week, they're "2way fit", what are the advantages, or otherwise, of leaving my innertubes behind and should I rush out for new tyres?

Thank you in advance.

Lower rolling resistance, ability to ride lower pressures safely (can't pinch flat) and the sealant's ability to deal with punctures. The problem is the expense/availability of tyres - pretty limited choice.

what MD said. Good grip and comfort from the lower pressure.

Hutchinson, Schwalbe, and Bonty do tyres in the UK. All are more £ compared to equivalent clinchers though.

Been tubeless on the mountain bike for years and would definitely never go back to tubed, but I like to run nice low pressures and I'm a bit over average weight so was forever getting pinch flats.
On the road I don't see quite as much advantage, though I suspect this will change as tyre and wheel choice improves.

I have a friend who went tubeless. He did his reserach and eventually bought a set of tyres from a retailer in France due to limited choice in the UK.

He ran these tyres at the bottom end of the recommended pressure range. After about 1200 miles he was down to the "fabric" of the tyre. This was a soft compound tyre so you would expect low mielgae but 1200 miles!

He has raised this with the manufacturer who initially stated that running at too low a pressure would increase the wear rate and they refused to consider a refund or look into the matter. After some pushing they have now asked that the tyres be sent back to them for examination.

We are awaiting the outcome - hence why I have not named the manufacturer.

Thank you all for your help

I built up a wheel set with Stan's No tube Alpha 240s on Novatec lightweight hubs (1250g). I've been using Schwalbe Ultremo tubeless. I run them at around 100 psi. Have to say they are fast and the ride is great but they are wearing quicker than I'd have hoped. I've killed three tyres so far, one hitting a rock and mashing the sidewall (the fact it deflated slower due to the liquid gak probably saved my neck), one got damaged on the car roof mount (I hadn't secured the front wheel well enough and it rubbed on a bolt head going through to the fabric, brand new tyre, wasn't happy). The third one just wore through to the fabric after about 1500 km, but some of that was on the appalling Kent roads, is that where the migratory pot holes go to mate? I put a flat spot on that tyre too when braking hard at a junction, locked the rear wheel for less than a second.

So great fast tyres, but I'll be keeping them for special occasions. The Scwalbe tubles kit isn't too bad value though, two tyes, latex liquid stuff and mounting potion. You'll need to buy the special valves as well though.

Somebody please make some genuine 28/30mm wide training tyres that I can run on my Velocity A23s!

If you don't mind tubing them, I recommend Vittoria Randonneur PRO 32... I've used them on A 23 in the Etape Cymru (and to commute along the canal path every day)... 5 hours 30 moving time in 90 miles with 2,500 mt of climbing... they're no slouch! They are awesome and you are likely to replace the wheels before the tyres are actually worn!

I did look into going tubeless but nothing seems to compare with those
