This refers to the style of connection between the seatstays and the seat tube. Waterford typically uses the clean Fastback design. Side tack designs offer a more traditional look. With some stainless lug designs, side tack stays are required because of the limited lug surface area. 14-Series and 33-Series designs have Fastback stay treatments.
