Any question answered...

Unless you have specific dimensions nobody can help.

The volume of a 195/50/15 is 6.52m (6520L)

I'm just working out the increased liteage at 27psi

i think the tyres are 82 profile.

10.9L

I'm not sure on the number of liters it would end up at, I'm probably not googling the right thing.

But then you also need to find out what the capacity of a CO2 canister is.

So now I have to ask: how many CO2 nangs would it take for the wind section of the Berlin Philharmonic to play the Eroica (with lute accompaniment, naturally)?

So now I have to ask: how many CO2 nangs would it take for Rikki Fredo to sound like Freddy Mercury singing 'Barcelona'?

The answer to this question has a lot to do with the survival of civilisation.

Ah, well, when you put it like that, who cares about civilisation? After all, what has civilisation ever done for us?

i am thinking about ditching the spare in the mgb, (as it takes up about 40% of the boot space) and carrying a co2 pump and some slime.

Have you looked into compact spare tyres? (Light-weight, narrow, higher pressure tyres designed to be just good enough to get you home / to a garage.)

or tyre weld.

↑This. It does exactly what it says on the tin.
Standard equipment on some new cars, instead of any kind of spare.

the aquaduct?

Currently have a shimano 105 golden arrow double chainset with 7400 DA 43t & 52t rings (130BCD?)
ultimately still trying to find an arabesque 600 chainset and change the rings over.
on the back have an 11-25t 600 freewheel, and an option of a 13-30t 600 freewheel (mech won't shift on it, as gap between gears are too great).
BUT
52/43t + 11-25t + 27" wheels is just too much for round here. Spend far too much time in the lowest gear and inevitably pushing on the steepest stuff (lakes passes).

Not my picture, but what is the smallest inner chain ring I can put on that? I'm assuming 38t or 39t. I briefly tried a 39t ring from another bike and TBH it didn't make the difference I'm after.

Q: Is there some magic CNC'd piece of kit that allows me to fit a smaller inner ring (30t region) to my 5bolt 130BCD
or am I going to have to step into the 21st century and get a modern compact or even a triple chainset? Ugly and overkill?

HTFU or...

You can use a 130/74 adaptor ring to convert what you have into a triple, but you'll need a new (longer) BB, new (triple) front dérailleur, and new (long cage) rear dérailleur.

Does anyone know where I can get some downtube cable stops that take the bosses with a circular base? Most of them seem to be the square ones like this

Any other solutions? I've managed to mangle some regular ones to fit but it looks ugly and they don't fit totally snug.

Is this any good?

If so, what is a sensible second hand price?

Very temperamental.

Ah, cheers Andy, might give it a miss.

Someone stole my Vision 1, looking for a replacement

the aquaduct?

Oh all right, apart from aquaducts, what has civilisation ever done for us?

Sliced bread?

no, no - genuine question.

165R14 (wire wheel with tube)

Don't. Not with wire wheels.
Unlike the controlled deflation of a tubeless tyre, when a tube punctures you get a total and more or less instant deflation of the wheel. Tubes are not self sealing, so while the tyre weld might work, it might well do fuck all.

What he said.
Still remember when it happened to my dad's car when I took it for a spin for the first time.

Is there a way to view only the images on a thread?
I'd like to see everyone's steamrollers posted here

No idea.
