How to deal with long pre-bled brake line? I bought and installed a set of pre-bled hydraulic brakes onto my bike to replace the mechanical discs that came with it. My future plan is to buy a new bike, transfer the brakes to my wife's bike and replace the old discs onto my bike and sell it.

In the meantime I have a very long rear line, about 30cm extra, that I'm struggling to manage. I've looped it and cable tied it on both sides of the loop, once back on itself and again to the front brake line. Unfortunately this solution slips a lot so I'm looking for a better one. At this stage performance of the brakes seems ok with this method.

Does anyone know of a better solution or is getting them shortened by my LBS the way to go?
Shortening the hoses isn't much more than a 10 minute job on most models. You'll need either a bike shop, or some nice cutters and a new olive and insert which will cost a dollar/pound or two.

Although, as these are moving to a new bike, I'd leave them be and do a more thorough job of looping them until you can measure them on the new bike. What are you using, my first stop would be zip ties and if that slips still, duct/duck tape. When you move them, a little alcohol will lift any sticky mess that's left.

You wont hurt the performance of the brakes unless you kink the hose. Don't do that. They'll want replacing if you do.
