to enable higher drop bars for old fart.
Litespeed Veneto is one (now out of production). Don't really want to waste time waiting for a used one to come up on bike.jaxed.com. Life is too short--then one finally comes up on ebay and some guy like me is willing to pay a king's ransom.
Custom-made is another choice.
Huge stack of spacers on uncut steerer or "steerer extender" on cut steerer are other choices. I'm using both of these options presently. They get the job done, but I'd like a more polished solution (possible pun).
What I don't understand is what you older guys are riding with drop bars. I've always been limber, but now at 65 I'm more comfortable with the top of the bar several inches above the seat.
Are there other stock frames out there with shorter top tubes and taller head tubes?
