I use those yellow clamping pads that Shimano put in with their brakes held in a vice to give me a straight line and solid grip and then a new stanley knife blade to cut the hose. Then I gently tap in the barb with a light hammer. Not been a problem so far.
Do I need the hose cutter and barb tool to put hoses on or can I make do with some plumbing snips that make a neat job on 15mm barrier pipe?
It’s routing that bothers me. How likely is it I’ll need to take the BB out?
I’m trying to avoid a minimum two week wait at my LBS which won’t allow you to book a bike in on a specific day.
