Ok, I was out yesterday learning steamroller barflips. I have front and back diacompe tech77 levers and the inside of the levers are sharp as hell. I ended up getting a ton of gouges on the inside finger of the hand I was using to flip the bars. I only need the back brakes for a bit longer, till i wire my time machines (safety net), but either way-then I will want to run double fronts. Anyone have experience with fileing down the inside edges of the levers, had the same problem, or know of a better lever? Thanks guys!
