I did find out from bike store people that a faster century has more to do with the rider than the bike. I guess I would have to find out if the bike I'm considering weighs less than my 7.3 fx. I also think that if my husband had a little computer on his bike we'd train harder and more efficiently. As it is, if he slacks off a little I do too, and I think we're capable of better times if we worked harder. Problem is, I still want it to be fun!
I will still be searching at some point, just because we don't have enough bikes yet.
