So the bike I just built up for my girlfriend has 26x1 3/8 tires with crappy steel rims. I'm hoping to lace decent 700c rims to the hubs and put on decent tires in order to give the bike a nicer and more effortless ride. Please correct me if this won't make much difference. The space between the tire and fork crown/brake bridge measures close to 1". ...Keeping in mind I'm not trying to fit 700x23 tires. I'm looking to put something larger and "comfortable" on there more similar in width to the 26x1 3/8 on there now.
Just for the sake of possibly bringing humor to some of you, I'll let it be known that this may well end up being a cheap, heavy gas-pipe C.ITOH girls frame with 7800 Dura-Ace cranks and brakes, decent aluminum bars, decent 700c rims laced to the stock crap hubs(narrow sizing on front hub and Shimano 3sp rear), nice platform pedals, and big crappy cushy 2lb seat. Totally funny build, but she likes the ride and it gets her out on a bike with me, so that's what it shall be.
Hundreds of dollars worth of parts on really low end 70s frame with heavy seat - $?00
Finally finding the goofy/crappy bike your girlfriend likes and will happily ride with you -
