Using two tubes .

[fasterjason]

most people[including Tasmanians] have seen a valve sticking thru a rim

I think you should take the next step and drill a third hole in the rim and install a beadlock just in case both tubes puncture. That will keep one or both valve stems from pulling out of the tubes while riding back flat. Then you can still patch the tubes.

We need to take a step back and address the innertube things properly. Just using two existing tubes or 4 , or whatever, doesn't necessarily improve things ..

I'm proposing a none circular tube ! The Sausage !!

A Sausage should conform to the international sausage standard 20cm length.

For a 27.5 wheel, you'll need 10 standard Sausages and 10 valve holes. For a 29er you'll need 11 standard Sausages and 11 valve holes - lets not worry about spokes ...

Obviously being the bike industry, everyone will rush to develop their own proprietary Sausage standard purely to make everyone's life difficult.

The great thing with the Sausage is that anyone can carry a pack of Sausages as they're light and take up hardly any space. Four Sausages and you're covered for 4 punctures !

The other great thing with the Sausage is that you don't have to remove the wheel to change a Sausage - even more ideal for hub motored bikes. Just find your limp sausage by feeling round your rim, or have a friend feel round your rim and see if they can find your limp Sausage.

Swap out your Sausage, add a tiny bit of air - which takes seconds, and you're off !! Mere seconds for a trailside flat.

Another advantage of the Sausage system is that you can most likely continue even if you lose one or two Sausages until you're at the bottom of your run. OK, performance will degrade slightly, but you should get away with it.

Most people will probably also elect to run the Slime Sausage, though if you're a major Sausage gobbler, you'd probably be better switching to tubeless.

I don’t want to drill any more valve holes in my new carbon rims but most would agree that this thread is an excellent source of information and inspiration.

My problem is that I slide around on my saddle a lot during a ride. Any ideas?

I could sacrifice a spare saddle if I have to.

If NASA, or some famous restaurant chain, saw this post, you’d be permanently employed as an advisor. Thinking outside of the box is awesome .

Great …now I’m hungry again.

If you don't want to slide, I suggest grip tape. If you want more room to slide, this....

Mayor tyre brands are close to those sizzling new products! I only received insider marketing details and It is not yet disclosed to the public as still being tested during selected group night rides of EMTB-forum gourmet riders only.

Integrated cheese style sealant!

Aussie origin ingredients!

Thank gawd I saw this post before I drilled a hole in the centre of the saddle and fixed the end of a wooden broom stick (4”). You may have saved me

Answering this in the spirit of being helpful but also taking the piss, like most replies to this thread.
The grip tape on saddle is a "Oh, no, no, no" from me, just ask Tony Martin,

Sandpaper saddle injury adds to pain of Tony Martin's World Championships defeat

Grip tape on the three-time World Champion's saddle rubs all the way through skinsuit padding

www.cyclingweekly.com

I remember seeing that live at the time, 9 years ago jeez, thought it was on the Tour but no, WC . Not a good idea, a real pain in the arse. One of commentators sort of predicted the outcome.
On the other hand you could fix a suitably sized butt-plug to your saddle and modify your shorts in a similar fashion to Tony Martin above.

 

[Zimmerframe]

suitably sized butt-plug

In the interest of science and staying on thread, would you suggest for more extreme riding or if he has long term issues using a standard single plug, would it be possible to switch to dual plugs ?

Surely that's a saddle for female use?

If the op can fit two tubes in his rim, who am I to judge the type of riding and rim diameter of @Stihldog ...

Surely gender would matter …butt so would your personal pain tolerance

The multiple sausage theory has some merit for tire survival …but if it was combined with this;

…when riding and entertainment when stopping at a pub!

Things are starting to take shape for this flat tire issue …unless someone throws a wrench in these ideas or accidentally saws off a wooden broom stick to a predetermined measured length.

 

[Arminius]

Somehow I thought to remember that (at least in the US) a flat tyre had a different meaning. Anyhow, this is fine too to enjoy the party. Prost!

As an American, I understand that you despise me and won't answer, but that's ok. I'm getting quite a bit of entertainment just watching from the sidelines. Even though you won't answer, please understand that the rest of the world doesn't believe you. If you want us to believe your furphie tale, you'll need to provide pictures. I understand that your tiny little camera is inadequate. Just borrow your mum's iPhone to take the pictures. She can text them to me, and I'll post them here in the forum.

My septic tank friend [septic tank=yank] , no, nobody despises you , don't beat yourself up over it , in fact , inside every German , French, English person there is an American [sometimes two]waiting to get out . Can you tell your Rhein reisling sipping ,sausage sucking German friend that those tubes have been invented , in the form of the 2 ends being closed to allow tube changes without removing the wheel.

When the shoulder stitching gave way on my favourite saddle, I had to do something fast. It was during the pandemic and nobody had anything to sell. I peeled apart the seat layer and the side layers and pasted in some PVA adhesive. Then I stitched them back together through the glue. I had to use a pair of pliers to push the needle through the layers of material and to pull it out the other side. Once done, I pasted some more PVA over the top of the stitching to waterproof it. It dried overnight. Although not sticky to the touch, on the next ride the saddle was gripping my shorts to a good extent. But after an hour my shorts-clad butt had polished the adhesive off and normal service was resumed. That stitching and glueing lasted longer than the original finish. No shorts were damaged during this experience.

Based upon personal experience, my suggestion would be to apply a layer of PVA to your saddle and allow it to dry overnight. I'm confident that would achieve your desired objective.

“Septic Friend” …ah man, another great trail name suggestion. Thanks !

Obviously a double black diamond trail with hidden tire puncture hazards everywhere …but safe and clear riding for anyone who has benefited from this thread.

 

[Arminius]

Well, during my ban , i did it ,and it works great . In a sharp rocky section of the track [where iv had several pinch flats] it was fine , wheel is more balanced , rolling resistance is better,, and , the dimwit that suggested that the tubes will catch fire from the friction , no it didn't .

It's a little known fact that Salvador Dali was a very accomplished mountain bike rider. He spent a year on the Brisbane downhill circuit. He had to quit, however, after his visa was revoked for his association with unsavory characters. Artistically, this was known as Dali's "Sausage Period." It's very curious, but if you compare the OP's birth date with Dali's residency down under... well... I don't want to be one to cast aspersions. The paintings below currently reside at SEMEN: Sydney Exhibit of Masterpieces and Expressionist Narratives.

These should work…..available in 27.5 and 29 inch

Since you are a Tasmanian i will answer you , I honestly did not think it needed photographic proof , most people[including Tasmanians] have seen a valve sticking thru a rim[think double vision after hitting that low branch], and its literally a 5 min job, take tyre off,drill, put tyre, tubes in [as normal], pump, job done.[also , my phone has like a 1 megapixel camera , wont see any detail]

I was generally interested to see how the two tubes fitted in the tyre.

Do they sit side by side, on one top of the other or do they spiral around in some kind of DNA like shape?

I put them in side by side , but i used skinny kmart roadbike tubes , use talcum powder so they slip into or find their place in the tyre/settle in the tyre , could also use dirtbike mouse lube .[if you do it , let me know how it went]

I just go tubeless. I rarely get a puncture and if I do the sealant fixes it 99% of the time and if it doesn't a plug usually does.
