I use gear cable inners in brake outer to reduce drag between cable and outer. (Doesn’t work with old Deore LX v-brake levers though as the nipple pulls through) and it gives a more positive feel and lighter action at the lever. I’ve yet to die in a humungous fireball in 5+ years of testing this set-up
Also found that Blank BMX levers and the road version of BB7’s give a good powerful set-up too (Converted drop bar to flat bar CX)
Oh and anyone got a spare outboard pad adjuster knocking about?
