Yeah, I'm deciding between the fx 7.2 with or without disc brakes. It's a big difference in pricing. I could use the extra funds to get extra supplies needed ( new helmet, computer, seat bag, etc). With living on the eastern shore, MD, is fairly flat here. But i do travel frequently and will start taking the bike on trips with me, yet don't really think at this point spending the additional $110 is worth it.
I have heard that disc brakes puts more pressure on the forks, rims and spokes. With already being a 300+ lbs rider, I don't need that extra strain on the bike.
