I have a very similar Interclub with the Durax cranks and Pivo stem. Its a very nice looking bike and the workmanship is a cut above similar era Peugeots that i've restored. The frame seems to be about the same weight as the Peugeot Carbolite frames. It feels great on the road, a combination of the heavier frame and superlight tubular tires and rims I think. I agree with Grand Bois....keep the cottered crank. A Brooks Swallow or even VO #6 saddle in honey looks great with the green color.
