I have 13 SSFG bikes that I ride on the road. The lowest gearing is 56.7 gi on my Salsa Casseroll SS with 42 x 20 and a 700x32c rear tire. The highest is 75.5 gi on my Bianchi Pista Concept FG with 46 x 16 and a 700c 22mm tubular rear tire. The Casseroll has no foot retention and weighs 28 lbs with the saddlebags unladen. The Pista Concept has full clipless road pedal foot retention and weighs 16.7 lbs. What gearing do you use ?
