Thanks for the info! I probably will go with 700x28 rims, the side pull brakes have enough pad adjustment to drop at least 1 cm. To open the rear frame 2mm per side seems doable. If I can get a 6 speed cassette with the same or similar high gear great or just upgrade a new 5 speed cassette? The brakes have no id marks on them, probably stock. Can go with anything save for cantilevered brakes. Just want to make it mine. Its black with chrome rims now, want maybe black anodized rims? new shifter/brake index shifters, we will see. Thanks again
Chuck
