Strawberry stock "Sport" 700c and "Rambler" 650b road framesets are offered here for cyclists looking to purchase a fine handbuilt frameset (frame + fork + headset). The frames are hand brass brazed in Reynolds 631 or 853 Air Hardening steel tubing. Why brass brazing? Reynolds 631 pre-brazed strength is in the range of 800-900 MPa (116,100 psi - 130,600 psi) and 853 is in the range of 1200-1400 MPa ( 174,120 - 203,140psi) and the after brazed strength is significantly higher. Quoting Reynolds " The strength to weight ratio of the air hardening steels is equal to that of quality titanium and aluminum frames. A normal chrome molybdenum steel will lose strength in the joints after the heat has been applied. This material (631 and 853) INCREASES in strength when heated to around 850 degrees C (1560 degrees F), (note: 850 degrees is the BRASS BRAZING temperature - silver brazing does not achieve this increase in strength) and the recommended braze metal is used per AWS Classification, RBCuZn type. As the frame cools the tubing increases in strength to well in excess of the as delivered values shown above. This unique air hardening property of Reynolds 631 and 853 provides additional stiffness through reduced micro-yielding at the joints, allowing stiffer frames with excellent fatigue strength when compared to standard chrome molybdenum and excellent ride quality to be constructed." An Enve road carbon fork is matched to the 700c frame (650b frames have a steel fork with the Strawberry designed double plate style fork crown) and is sold assembled with a 1-1/8" headset. The frames are fabricated with Marchetti fixtures in the Strawberry Workshop (shop pics may be viewed by clicking on the Mechanique link), Portland, Oregon by Andy Newlands who has over forty five years experience in the cycles engineering and fabrication field. Materials include the finest investment cast bottom bracket (English threading), lugs, dropouts, Strawberry designed wishbone rear triangle with the new LAN71 Integrated Seatpost Binder, and full compliment of braze-on's. Cost is $2500 for Reynolds 631 and $2600 for Reynolds 853 tubing,Ex Works, Goose Hollow, Portland, OR, or $2600 for a 631 frameset or $2700 for a 853 frameset delivered via UPS Ground throughout the lower 48 states. Sorry, no international shipping. As the framesets are completed they will be available for viewing at the Strawberry workshop and also posted here on the Strawberry website.
