It's a little bit more expensive than normal lines (unless you ride a 2009-2010 cabrinha or Ozone then it's CHEAPER to get Q-line) - but yes it does come on a roll so you can make up 21.5698cm lines if you choose. It's also fun to make them yourself - teaches you a bit about how your bar works and you can fully appreciate the awesomeness of Qlines

Each roll comes with 55m of Qline - So you need 2 rolls to make up a bar, make sure you get two different colours or tangles will be a nightmare (I hope you're listening SLINGSHOT!)
