Thanks! I have always had a road bike and I bought a new FX Sport 6. I was caught by surprise how technical bikes have become and hybrids are truly hybrids of their own imagination. Posting in the Mechanics Forum is a good idea and I will start a thread there. I think the flat bar levers are more powerful which would make sense due to mountain bikes in general being heavier, have heavier calipers, heavier wheels, heavier tires, demand more hard on/off use, etc. I hope the olives, fittings, and brakelines match up. I wasn't planning on doing all this (or at least right away), but the bike came with Promax brakes.
