I’ve got the rack and bag shelved. I’ll drag them out again soon with a more positive attitude. The modified diving board that I experimented with put the bolts barely above the tire and the 5 or 10mm that could be gained by finding some middle ground are not enough to give my hands as much room as they need. Looks like a decaleur is warranted. Going through Gugie’s link above is worthwhile if you haven’t done it yet. I’ve admired many of his photos when they are posted on the forum but the process shots and all the rest of his flicker record is impressive.
