For my Peugeot Clubman commuter project, I'm building my FW into a 700c velocity dyad and a dynohub into the front wheel. The FW has an 18t cog. My Peugeot's small chain ring is 40t (the big one is 52...I don't have the legs for that combo). I have a cotter press so servicing the French bottom bracket and cranks is not a big deal, and I would like to retain them. My question is: will the 40t be too small in combination with the four-speed and 18t cog? Or would that be an ideal setup? I'm new to gearing discussions, so just curious. Any suggestions? Thanks. The bike will be used for commutes in all weather conditions and day rides. The Ottawa valley isn't very hilly, and my various route options are relatively flat.
