Inner tubes

this might be a boring thread but i couldn't find anything on search and it'd be useful to know...

what inner tubes do people use? for my current bike i tend to use whatever i can get at the time, in fact i can't even remember what i'm running at the moment... but i used to be really picky about mtb tubes. how much difference do you think this makes for road/track bikes anyway? are there puncture resistant 700 tubes available?

Cheap ones, I stock up at Herne Hill... 2 quid a pop for the long valve Contis, Race 28s... Not that I need them that often...

I recently made the executive decision to only use inner tubes with unthreaded valves (beyond the dust cap thread).

So many valves are now stupidly threaded all the way down to the rubber, and allow air to escape from the valve/pump washer interface. It irritates the fuck out of me.

I'm now a happy user of Michelin Aircomp Ultralight (Butyl) in 36mm valve, and not bad at around £2.75 each if you shop around (eg. Ribble, ebay seller).

I could be bothered cross-posting for this particular gem of information.

one bike has specialised in as these seem to be the most widely available (evans, etc.) but just bought two new tubes, schwalbe, from the London Fields Cycles. nice long valve for the deep V's but six quid a pop. that is just wrong.

can't imagine tubes make much of a difference though and would never fuss about it. just whatever i can get when needed

Anybody used the replaceable valves? I've given up on Specialized tubes because the valves kept on breaking and have bought some spare valves just in case it happens with other tubes.

It looks like only some tubes have replaceable valves anyway, but it's got to be less irritating than using a hand pump to get to 120 psi only for the valve to break and start leaking air.

Haven't had an opportunity to replace any yet since I bought them...

ribble are super cheap so are bike basket with conti's at £1.50 for long valve, booyah!

2 for £2.00 at decathlon shortish valve but by far the cheapest

do bontis thread all the way?

Don't know.

The Michelins were the first short-valve-no-thread that I happened across, and at that price (and reliability since)*, I'm happy to stick with what little I know :)

*and weight

is a 700x18-25 tubes stretching it on a 700x28 (or even 700x32 tyre)?

I use 18-25s for my 28tyres. Seems to work fine.

I agree with Object - and it saves weight too.

Not sure about latex tubes in the same situation though...

And everyone knows that my main concern when building a bike is the weight.

You can save even more weight by painting your bikes in a light colour.

I reduce the weight of my bikes by scratching the paint off them.

Remember: Deep gouges in your frame will make it weight less.

As will keeping the mood light by singing a wartime ditty whilst riding.

I think I'm going to start removing all of my jewellery and weighing my t-shirts to find the optimum rider weight ratio.

I'll also be doing more scarification and less tattooing as everyone knows ink weights a shitload.

And carrying around the shame of repeatedly using a noun where a verb is required.

Storing the required information in my brain, to acknowledge your retort, would weigh me down considerably.
