Hey everyone, does anyone know the brake line lenghts on the 2018 Trek roscoe 8 17.5" model. I just bought new brakes and need the lines shortened for better fit. Thanks in advance.

You can lay the new brakes and your old out next to each other and just match the lengths. Or you can install the new and eyeball what looks like enough.

I’ve never seen a specific length specified for any brakes.

When you have the hose disconnected from the master cylinder (or lever I guess they call it), turn the bars to the fullest in each direction, all while holding the hose to the lever. Give the hose just enough slack that the hose won't be damaged in the event of a crash and the bars wrap around.

Mark that length and make your cut.
