The Giant TCR DISC I’ve had for the last two years has a front brake line that looks like a skipping rope hanging off the front of the bike. It’s way too long. Today I go about fixing this myself armed with the right tools and after watching way too many YouTube videos on hydraulic brakes (and hydraulic theory…. ok, I was bored!).
