Just a thought as a lot of forum members have been asking about Zero Grav brakes........When Disc brakes become available for road bikes do you think you will use them? I guess you will need to have a compatible frame too though. The main question is will you use them, since unless I am mistaken-- they are still heavier than v brakes when put on mountain bikes, so they will still be heavier for raod bikes. Will better power outweigh weight? I'll stop now, I'm rambling....
