Tubular Tyre - Sealant

ROK ON

some advice required.

Recent owner of a set of 50mm carbon wheels with tubular tyres.

Astra Monti has suggested that I don't put in tyre sealant and use instead a can of emergency sealant in the event of punctures.

What do people here recommend?

Does anyone use sealant, if so what brand and is it easy to get into say a Conti GP4000s 21mm tubular tyre?

Does anyone use nothing?
Has anyone used something like Effetto Espresso, if so how did you find it.

I will be using the wheels for racing and cycling to the race circuit (never more than 25km from home). So I am only seeking a solution that gets me 25km in the event of a puncture.

Thanks

Just bought a can of Vittoria Pit Stop. No need to use it yet though so I dunno if it's any good.

If the valve on the tub comes apart you can use this : http://www.planet-x-bikes.co.uk/i/q/WSTUSE/tufo_extreme_sealant Looks a little easier to carry.

I almost bought this today but guy in shop said it will last about 3km - and it says so on the bike.

I'd walk 3k, I'm seeking something that will get me home from 20-30km

I'd use one of these myself...

I've been using Effetto Mariposa Cafe Latex sealant on my tubeless wheels the last number of years - has performed well the few occasions where I've had a puncture. A little slower to seal up in wet conditions (not really surprising) but never had a flat while using it, 10-15psi pressure loss. Max. I recently went to Ultremo tubeless which uses Schwalbe branded Stans sealant but luckily haven't had reason to experience how well it does its job.

As it happens I'm actually in the market for 50-60mm deep tubular wheels at the moment and due to a bit of apprehension about running tubs without constant team car support have been reading up on sealants. Have read very favourable reports of using Stans NoTubes sealant with tubulars but opinion is divided between having it in from word go or carrying it and adding it after picking up a puncture.

Is it easy to get into the tube?

Do you need to detach the nozzle from the tube and use an injector?

It's not too bad, the Cafe Latex kit I have came with a syringe which has a connecting tube (with optional schrader adapter) to which you connect to the valve.

With most tubeless valves it's been just a case of screwing the core out, turning the wheel so that the valve is at 12 o'clock and injecting it in, it should be the same for similarly valved tubs.

I've put some into club mates tubs where the core was non-removable by using the schrader adapter with a presta adapter to make sure everything stayed connected while injecting it with no trouble.

It's a very thin liquid so it provides little resistance passing through the valve, the key thing is to have the valve pointing down so that it runs into tyre and can't spray back out (and all over the place) when you disconnect the tube/syringe.

Can't say much about the Stans sealant, having used it just once it seemed a bit thicker, maybe a bit granular, but was going into a valve where the core was removed so there was little in the way of resistance to it.

I use nothing in mine.

I've used Pit Stop in the past, albeit on clinchers. It's like Sex Panther, 50 per cent of the time it works all of the time.

I've used Stans once on a tub flat before. It worked. But I reckon all sealants will only work with holes of certain sizes.

I think the best solution though is to bring a spare tub and whack it on in the event of a puncture and just take it easy on the corners getting home.
