ivan here from florida. i recently bought a 10 year old 4500 and would like to know what i can upgrade on a budget. it rides well with the only problem being when shifting from 2 to 3 on the crank, i have to push the lever twice to get it to catch. other than that, it is ok.
i may replace the saddle for a more comfortable one. i am thinking of replacing the crank, chain and cassette as well. what parts could and should i get? do i need to? any and all suggestions are appreciated. thank you.
oh, and what sites are good for buying parts.
