How much more of a setback do you need?
You could try a new seatpost and a slightly longer stem.
BTW, I, too, have the Gran Cru seatpost and have had zero problems with it.
If you think the bolts may snap on you, start out with stronger bolts. [MENTION=192132]Drew Eckhardt[/MENTION]'s experience was certainly horrific and is not to be discounted,
but I think sturdier bolts would resolve any issues.
