What size tube for a 20" qu-ax trials

(by the way this is dudewithasock on monkeyman’s account)

I got a nasty 3/4" tear in my tube and I’m getting it patched up, but I’d still like to get a new tube cause this one has seen a good deal of action. What type should I get? Just a regular 20" bike tube at the LBS?

BTW, the tire is a CC 20x2.5.

Most likely your LBS will only sell 1.75x2.0" tubes (http://www.einradladen.net/shop/show_product.php/cPath/15/products_id/38) but you need a 2.5x2.7" tube, the other one will roll a bit in your tire (http://www.einradladen.net/shop/show_product.php/cPath/15/products_id/82).
