I got the Big O down and took her out for a 10 mile spin today. I've been riding my newer bike because the top tube is shorter and a little easier to reach the handlebars and shifters. But tonight was a great ride. The Voyageur brought back lots of old habits, reaching for the barcons, silding my foot into the toe clips, shifting patterns, etc. Then after about 7 miles, I notice a "catch" while pedaling. I feel it with my left foot when it is even with the chainstay. It didn't matter if I was in the large or small chainring. When I got home I checked for loose cranks, loose bottom bracket, frozen links, bad teeth and nothing! If there is no load, there is no catch. If I put the bike in a rack and spin the cranks, no catch. If I ride in any gear and have some force on the pedals, the catch is there. Same place every time. Any ideas for me that I can check?
