Now- road BB5 or MTB BB5? I've used those Tektro levers with a road BB5 before and 'twas awesome, would an MTB one be more awesome?
I would guess the modulation would be better MTB-MTB. But have no experiance of this.
MTB levers pull more cable, but with a little less force. So with a road caliper I'd expect you to bottom out quickly. So you engage the caliper before your done pulling the lever all the way. The MTB caliper will move less for the same cable pull, and therefore offer more mudulation. Both are OK. Using a road lever with a MTB caliper is the dodgey one.
