Spare tub/ sealant options

[Zacnici]

So Hussler did you pretreat with Specialized or was it it a repair? As I'm very new to tubs have not pretreated as still weighing up; I had looked at the various sealanst and at the time Specialized had pulled their Airlock Pro Sealant, their stop notice has now been deleted but cached on Google search:

Due to the poor performance in extreme conditions, we are asking the Dealers to stop selling the Specialized Airlock Pro Sealant. This notice is not safety related, only performance related. This letter is to inform the dealers to remove the product from the shelf and to stop selling the current Pro Lock in all sizes.
Dealers/customers who are dissatisfied with the performance of the Airlock Pro Sealant can receive a credit at the store and the dealer can apply this to their Warranty Credit form.

Our Tire/Tube Developers are currently working on an improved compound that will meet the rigorous standards of both Specialized and our valued customers.

Following your post did a search and Specilized describe the sealant:

Our newly redeveloped self sealant is now available in bottled form to make any tube Airlock'd and puncture proof. Technical features surpass the competition in flat protection performance

So by the sound of it you have the new stuff and as you have the same tyres, Continetal Competitions (on your recommendation - and I'm very pleased with them), reckon I will go for that in pretreating. I'll still carry my Pit Stop, spare tub, and CO2 carts as I'm paranoid like that.

I didnt pre treat them...

A couple of years ago, continental used to say pre stretch the tubs by standing on them with the valve between your feet and pulling up..... loads of guys I know used to do this too....
So thats what I used to do....

Then last year I noticed that my brand new tub I had put on prior to the Tour of the Peak, punctured during the TOTP, I used the pitstop and it didnt work.... so I swapped the punctured one for my spare....well I tried too...I had forgot to put the extender on the valve of the spare and couldnt remove the old one on the punctured one..... so I walked back to my car and went home.

Now when I got home I Did a few tests with a product called Stans no tube sealant, from their website video it showed the guy slicing the tyre with a knife and hammering nails in it etc and the tyre stayed up so I thought this has too seal my Tub.

Nope, it didnt work either.... but it did highlight why I had punctured!

Their were more holes in it than a fish net! all along the stitching.....
This was due to me using continentals old way of pre stretching, it had actually tore the Tube inside the Tub away from the stitching and therefore loads of holes everywhere.... I had pre stretched my tub on my disc wheel the same way and it would deflate in a matter of 60 miles if riding and if not riding then 24 hours.....

I then used the specialised stuff in this tub on my disc......and its plugged it all and apart from being quite messy it has stayed up since! Yes it is slightly heavier, not by much and it still rolls evenly!

I would recommend pre treating deffo with this stuff, but I havent had a puncture since using it so cant say if it would actually plug a puncture if it happened after pre treating them.....

Hi,

Going through the same pondering process as got my tubs fitted with valve extenders (planet x ones - cheaper than wiggle) and got a tri in 3 weeks.

I bought some slime from Wilkinsons for £5 and intend to put half in each tub via the removeable valve core.

Will let you know what happens.
