Holdsworth Super Professional Reynolds 753 Steel Collectible Bike 55cm Rare
This frame is a 'modern' version of the racing Holdsworth's of the 1970's, in team colours. It was built as a show bike for Holdsworth and has only been displayed at bike shows, built-up but never ridden, in essentially new condition, except some paint has chipped at the seat lug. Chromed hand filed short point lugs, authentic orange and dark blue livery, ultra rare straight fork blades and of course extra lightweight Reynolds 753 tubing throughout. This was one of frames built with the 100 last remaining 753 tube sets left in existence and I have never seen another of those frames with straight forks, so this is the rarest of the rare. Size 55 x 55cm c to c.
Reynolds 753 tubing was launched in 1976 and it was an immediate success. The tubes were based on a steel-manganese-molybdenum alloy but with an important addition, it was heat treated giving it immense stiffness and strength. In fact, Reynolds 753 was the first heat treated bicycle tube set, according to Reynolds. To see how advanced 753 was back in the day just take a look at its ultimate tensile strength of 1230Mpa, compare that to a current alloy of Reynolds 853 which has an ultimate tensile strength of 1200Mpa and you can see the alloy was incredibly strong (1Mpa= 1 N/mm² ).
753 was used by many pro riders such as Bernard Hinault and Greg Lemond, who both won the Tour de France on bikes built with Reynolds 753. But it was not only the pro’s who used 753, it was really sought after by most riders wanting the very best in the world, but at the time it was extremely expensive.
Also, Reynolds wouldn’t just let any frame builder build with 753, so builders that wanted to use it had to do a test and if they passed they gained certification from Reynolds, which allowed them to buy the tubes. 753 had to be low-temperature silver brazed with filler rods of 56% silver content. Back in the 1970’s and 1980’s frame builders would mostly braze with brass, which would ruin the properties of 753, so this meant only the very best frame builders could use these tubes.
Holdsworth secured the last remaining Reynolds 753 tube sets remaining in existence (100 sets), and this frame was custom built in the UK by master frame builder Mark Reilly from one of those those tubesets.
I have flat shipping rates to Canada at $90.00 CAD, or $135.00 CAD to the lower 48 states in the USA. All other destinations, please contact me for a shipping estimate. The frame will be professionally packed, in bubble wrap and foam, in a proper frame box.
