I've been over 30 ONCE (with brakes) on some sketchy roads during a group ride in southern Indiana in 2010 (Indysteel will remember that ride) - it was nervy. I've come close to 30 since then but never over it. If you can at all handle the cost get the bike fitting - it is well worth it and a good fitting will keep you comfortable on the bike for far longer than you will remember the cost.
