Busted inner tube valve/knob gizmo jobby..

[BigonaBianchi]

the end bit on th einner tube valve just snapped off, it's the bit you unscrew to inflate and then screw tight after.
So...erm...time for a new tube right?...or is there something else i can do...it's not the expense..it's the hassle...these arnt just tyres...these are..M&S ..erm..I mean Schwalbe marathon tyres

At least they aren't Marathon Pluses. Thank your lucky stars they are only the bog standard ones. I sympathise though .

It's just the tube that needs replaced though isn't it. £3 from the LBS. Or am I missing the joke

I've broken the inner pin thing (the bit you push down to release the air) a couple of times, no doubt caused by overtightening of the little screw down bit. It did it once as I was screwing it back on and it came shooting out at the speed of sound, rebounded off the rim and took a nick out the wallpaper on the wall 2ft away. I thank god I wasn't in its path and I get very nervous pumping my tyres up these days.

..actually these are marathon pluses ...hmm..ok looks like I shall have to do battle with them then.

It's the tyres that are a pain - don't blame you..... yup new tube.....

The tube is a scrapun.

Were you pumping the tube up with a hand-pump? and slipped?

Tip - Get a DEEP flexible coupler from an old type pump. This screws over the Presta and the hand-pump fastens on the flexy end.

Hey presta,,, Presto!
