RAGBRAI!
I'm going to pedal the 110 miles to Marengo in 2 half centuries+(Hey! I'm staring at the half century mark myself) and then ride the last two stages of RAGBRAI to Muscatine. I'm sure my 1970's Fuji would have sufficed.
But then I spotted a sub 4 pound Sakae frame on Ebay for $150, shipping included (
)
I'm getting the components from Ebay, the Salvation Army & other thrifts, off my shelves in the garage, and a few things like spokes and cables from the LBS.
I think I should have a pretty decent, if somewhat cobbled together, ride for under $300 bucks.
