A bold move ?

[jimboalee]

That's it!
P******e this morning.
Found front flat at lunch time.

My bold move is to buy a pair of Shox SOLID 26 x 1 ( 25 - 590 ) tyres in Black.

Front is OK, but I HATE repairing a rear with a Sturmey in the wet and dark, so these will cancel that experience entirely.


Wish me luck.

Should work wonders for ride quality...

 

[yello]

Good luck!

I have to say that whilst I'd like to say that I'm open to all ideas, there are certainly some ideas that I am more open to than others. And solid tyres get the full Roger Moore raised eyebrow.

Yikes. I remember reading someone saying something along the lines of 'every now and then the idea of solid tyres gains a brief flurry of interest, then everyone realises what a truly terrible idea they are, then everything goes quiet again'. I'd do a bit of googling first personally. Loads of stuff like: "I tried solid tyres years ago. They did not provide the same shock-absorbtion - this led to vibration which caused the front fork to crack and almost caused a serious accident."

Good luck sunshine....you won't be riding fast with those...... you just fubar'ed the handling........ Best Wishes...... crazy fella....

 

[PpPete]

but what was the bike speed /handling before this "bold move" ????

I'm guessing this ain't no modern roadie machine.... 590 tyres... that is really old skool, right jimbo?

I only know this becuz I was thinking I needed some 35 x 590 for my latest project but it turns out it's on 32 x 597 (rarer than rocking horse sh&te that has been pecked over by hen's teeth)

And the rest of us were thinking that mister Dunlop might have been on to something...

 

[jimboalee]

No worries people

I've found Schwalbe do 37 -590 ( 26 x 1 3/8 old skool steel rims ) Marathon Plus with Smartguard.

Sorry, a momentary lapse of sensibility after running around between bike sheds and washrooms.

All sanity has returned now. Thanks folks.

PS all commuters, KEEP THIS LINK !

surely the technology has to exist to make some sort of bubble wrap type inner tube with losts of small bubbles that by some means can be pumped up to high pressure when tube is in tyre - gas from chemical reaction?

if you get a nail/thorn/glass shard, then only a small number of bubbles are affected and if they are small enough, the tyre will not only stay up but will not get a flat spot in that area?

I have thought of fitting 2 or more inner tubes in a wheel so if one is pierced, then the other one will have enough air to keep you rolling.

I think you are ripe for the Dragon's Den

it's the "by some means" that you need to work on. and why it hasn't happened yet. start your research with car airbag technology, they emit nitrogen iirc. Your research will probably fairly quickly stumble across a stumbling block as to why it isn't appropriate for a tyre though.

Besides wouldn't the rolling resistance still be about 100x what it would be for a normal tyre, due to all that extra rubber to compress?

and heavier.

 

[jimboalee]

02GF74. Its been done.

They are called 'Greentyres'.

They have an outer skin as per a normal tyre and the 'solid' inner is a foam of bubbles.
The equivalent hardness is 65 psi for a 37 - 590.

There are 700C sizes which have an equivalent hardness of 100 psi.

There has even been a 'foam inflator' which fills a normal inner with pressurised foam.

The downside is, as you say, the weight. 37 - 590 is 850g ! Too heavy even for my Gents upright.

The Schwalbe tyres I am now leaning to are heavier due to the puncture resist belt, but not as heavy as the Greentyre.

PS There is not much in cycling that hasn't been tried before, even a small turbojet engine on the backrack ! No effort, but no paint on the bus following

Update.

TWO P*'s in one week. That's not funny.

Considering I am riding on Raleigh Record 37 -590 (26 x 1 3/8") with no puncture protection, that's still too frequent for normality.

I took a stroll up to the Island just outside where I work, and some B has smashed a bottle by the bus stop.

I checked some online shops and Schwalbe Marathon Plus are £22. Hmm.. and 800 gramms each !. They are effectively HALF SOLID having a thick band of soft plastic under the outer casing.

While I repairing the second pu**..., I remembered Steve at Kelvin Cycles gave me a tube of Bike Doctor tube sealant. I have been reluctant to use it (has anyone used it?). I've used OKO in my Trail motorcycle tyres and that worked.

The additional weight is only 100g per tyre, so I will squirt the stuff in tomorrow.

That is the lowest cost option first.
