Here's 2m of 1.5mm Stainless Steel Brake Cable made by Jagwire. It is suitable for SRAM and Shimano setups. It's been pre-stretched, so it doesn't stretch as much for you, and it's surface has been smoothed to ensure your shifting is low friction. On top of that, it's stainless steel so it won't corrode.

Also included is two cable end caps - just in case. You even get to choose what colour they are! :)

We offer two types of brake cables Road and MTB. The difference between the two is the shape of cable head. Below is an image which you can use to decide which type you need.
