I have mixed feelings about running hoses internally. While they will be less out and about this will require a drain down, refill and bleeding. As the hoses and cylinders will retain some fluid the chance of a lot of air at various spots is less. But air can get trapped easily even in a system that has well wetted insides before filling. If you're going to cut down hose length consider getting a spare rear hose just in case you find out you cut one too short after riding the bike for real after the install. Andy
