Hi,When I first contacted Richard in the middle of Sept. and presented what I was interested in regarding the frame geometry and weight, he replied back that he was more than capable of fulfilling my wishes. So we proceed on with the price, deposit & contract. The frame design went multiple times back an forth, with Richards cad drawings until I finally agreed upon the design. I can't say enough how professional Filament Cycles handles there business. A delivery date was set for the 1st. week of March and that's when the frame arrived.
