Grip the two little flat bits just below where it snapped and unscrew
Then just replace with a new after getting a shook at the price
You'll need one of these: [url= http://www.chainreactioncycles.com/stans-no-tubes-presta-removable-valve-core/rp-prod38822?_$ja=tsid:46412|cgn:Stans+No+Tubes+-+Tubeless+Kits|cn:Chain+Reaction-UK-PLA-PLA-All-DT-SE|kw:132488UK_Stans+No+Tubes+Presta+Removable+Valve+Core&gclid=CJy7hZCBybkCFUXJtAod1VsASA ]Valve[/url]
There is a core remover tool but needle nose pliers work just as well. Core is less at £2 if I recall. No need to take tyre off. You can squirt sealant in through the hole with a plastic bottle with a pointy end too, should you need to.
I'll Be damned!!!! Pays to watch Youtube!
All over it, Cheers for the help!
Learning new things all the time!
Take the wheel to your local tyre place with a 'packetofbiscuitsinlieuofpayment'TM and they'll have the tool and a million and one perfectly servicable valve cores in their bin!
