I have the Silca ratchet+torque wrench set, and often carry it with me. It's been my default tool for assembling road bikes when travelling for years now, with usually a set of PB Swiss Allen keys as well. However, larger tools are easier to use, in some circumstances, and if I have to take a bleed kit with me I'm thinking of taking a more comprehensive kit. Also, I might smash bits off the MTB in a way that I never anticipate doing to the road bike.
