I just ran my gear inches on Sheldon's on-line calculator and with a 13-24 6-speed FW and 34 and 48 rings I have a low gear of 37.4 and a high of 97.4. These are quite workable. Personally I think maybe a 12-26 would be a little better but I don't have a FW with this configuration. Lastly this combination shifts fine on 30 year-old parts. enjoy, Brandon"monkeyman"Ives SB, CA
