Tubbies

[SwissVan]

Is there a sealant ala Stans that can be used in road tubbies if you get a puncture while riding / racing?

 

I'd imagine Stans or similar stuff would work but wondering if there are any official ones or if anyone has tried Stans.

I put 60 ml of bat seal in my tubbies , works like a charm .

Just don't bomb it the first time and you should get away with a puncher or two .

It looks like puncture prone tyres??

Pump this today ,it will loose 4 bar by the morning before you race ,

Very good tyre but I think the inners are a let down .

I got 2 x Conti 4,000 GP's......

 

So we shall see. Maybe I will get one of these as a spare...

My advise is go for the Specialized Roubaix tire 23/25 (= 23 running tread with 25 side walls)

 

Bomb proof, absorbs road shock really well, great rolling resistance an corners like a husband caught in the act.

 

Did the Satelite Classic on them with normal wheelset and avg 38km/h most of the way.

If you want fast.... Get bigger legs. If you want durable and comfy go with these.

Best of all... The are really well priced

Hey Guys/Ladies,

 

I have made the transition from clinchers to tubbies about 3 months ago. I have a pair of Rolf's 38 TDF with Conti Sprinter Gatorskin that I use sometimes for training but mostly for races.

 

My training wheels are Fulcrum Zero's tubbies that I use mainly for training and on occasion I might even race with them (Jock, Kremetart and Stage 1 &3 of the Panorama). They currently have the entry level Conti tire that is a Conti Giro. About 2 weeks ago on my training ride the Conti Giro developed a nipple on the centre surface. Took it to my LBS and they exchanged it no problem. It was a defect in the tire.

 

One question that you should ask yourself, how many times do your puncture a year? I ride about 10k kilometers a year and my average punctures per year is approx. 2 maybe 3. That is between 3-5k kilometers that I would puncture.

 

Another fact regarding tubbies, they can take higher pressure (11-12 bars), where as a clincher generally can only go up to (8-9 bars). That means that the tubbies will be a harder ride and the fact that they can take a higher pressure they will be more resistant to punctures.

 

Btw, I do not ride with slime. It defeats the purpose of riding tubbies and I have heard that it is a nightmare to maintain it.

 

To conclude, i cannot see myself returning back to to clinchers. I feel that these tires I have chosen are about the best puncture vs. cost vs. quality perspective.

Interesting

 

WRT to the slime / stans...agree and i did not think of that when i posted the question....however the trend would be to save the tubbies for important races and race only type wheels, not to use them on a regular basis. Still putting a sealant in would be a problem as you canot remove it as easy as you would with a "tubeless" tyre.

 

So, what options are there for race day punctures that can be carried with and used in the event of a puncture to quickly refill and seal?

[DMC007]

I would assume "Pitstop" will be used on race day should a puncture occur. I also just recently moved over to Tubbies.

I simply carry an extra tubbie. I have heard (not experienced it yet) that it is quicker to replace a tubbie than a clincher tube. Personally I would not trust a sealant when riding at 40km/h or even worse going downhill at 60km/h + on a "patched tire".

 

Anyway, if you experience the unfortunate circumstance of puncturing during a race, your race is esstentially over. Whether it takes you 2 minute or 5 minutes to replace the tube\tubbie you lost the bunch, then it is simply a ride to the finish. Enjoy the vibe, have a boerie on the side of the road, drink a beer etc.

For me I would trust the sealant more than I would trust a newly seated tubbie.

You will/should see the sealant stop working/fail.

You might not see the glue fail on the new tyre and they should sit for a while after being glued.

 

I have recently started riding tubbies on the MTB and have yet to puncture so don't know how the sealant will work,

will only put in once I get a puncture.

Hi Guys

 

I have the TUFO High Composite tyre in stock, some are older( June 2013) and will pass them on @ discounted prices to make room for my next order.

 

I also have tubular clinchers, for the non-believers out there that want to try tubbies on clincher rims.

 

Sealant is also available, and it works.

been using Vittoria Corsa Evo CX Tubular since 1997. Wouldn't think of using anything else.

 

If no punctures, would get easy 2000 + km on them. Never cycle with slime etc. you puncture in a race, you stop, get a lift back to start, get home put on new tubby period and hope new tubby last a decent number of kms

Well not as simple in Ironman. You pay R4,200 for an entry and train for 9 months. So you really do not want to puncture and if you do then you really want to fix it

I put Stans in my tubbies (road). Had a puncture a couple of months ago, and the sealant worked. When bombing it the puncture reopened, but sealed again at about 3-4bar. Was good enough to ride home on and fix permanently.
