The GRESINSKI frameset built from full Reynolds 531 tubing delivers a 58x57.5cm geometry and a declared weight of 2675g. The bottom bracket shell uses French 35x100 threading, while the fork steerer is cut to 25x100. A 121.5mm over-locknut dimension sets the rear spacing for period hubs. One dent is noted on the frame; the photographs form an integral part of the description and document its exact location.

For a narrower rear triangle and lighter overall frameset, the PEUGEOT PY10 Frameset FULL REYNOLDS 531 5/10 54x55cm 2185g 120mm spacing offers a smaller size and closer to 120mm rear spacing. If the build requires a taller front end, the PEUGEOT PX10 PY10 bicycle frame, FULL REYNOLDS 531, 3015g, 60x58.5cm, 126mm gives an extra centimetre of top tube and a wider 126mm OLD.
