I don't know if I'd call the V3 a "highracer." I reserve the racer moniker for bikes that are severely reclined, and the RANS just ain't. As far as aggravating your condition, that'll be hard to predict. On the one hand, the RANS seat is more reclined than a GRR, so you should get fewer seat problems, but OTOH some people in the past have had problems with the lip of the seat pan hitting their tailbone.
