It started reaching frame builders in 2005. [6] 953 is based on a specially developed maraging steel stainless steel alloy that can achieve a tensile strength in excess of 2000 MPa (853 is around 1400 MPa), giving a good strength-to-weight ratio. Because of the high strength of the steel, extremely thin tube walls (down to 0.3 mm) can be used ...
[i] [19] Stainless maraging steel is used in bicycle frames (e.g. Reynolds 953 introduced in 2013) [20] and golf club heads. [21] It is also used in surgical components and hypodermic syringes, but is not suitable for scalpel blades because the lack of carbon prevents it from holding a good cutting edge.
Frames are generally custom-built to a rider's required dimensions, and may use hand-cut lugs. [1] Mercian frames were traditionally built using steel, originally Reynolds 531, [ 1 ] though as of 2010, newer steels such as Reynolds 853 and Reynolds 953 and part- carbon construction were in use.

Reynolds 531 (pronounced 'five-three-one') is a brand name, registered to Reynolds Technology of Birmingham in the United Kingdom, for a manganese–molybdenum, medium-carbon steel tubing that was used in many quality applications, including race car chassis, aircraft components and, most famously, bicycle frame tubing. It is one of a number of ...
16-gauge Reynolds 531, a high-tensile manganese-molybdenum steel alloy, was used as it allowed the frame tubes to be made thinner for the same strength, as well as making for a more responsive frame. All the joints were Sifbronze welded, [ 27 ] [ 28 ] – a relatively low-temperature flame-braze – except for the sub frame which was initially ...
Roberts Cycles is a custom bicycle frame building business that was originally located in Selhurst near Croydon, South London, and is now located in East Sussex, England. The business began soon after World War II when Charles (Charlie) Benjamin Roberts worked as a frame-builder for Holdsworth, Claud Butler, and Freddie Grubb. In the 1960s ...
Tange International Co. is a major Japanese manufacturer of high-quality steel tubing [1] for bicycle frames, established before 1920. [2] They are a rival to the British-based tubing manufacturer Reynolds. Where the de facto standard of bicycle tubing from European bike boom bikes is Reynolds steel, the Japanese de facto standard is Tange ...
"653 - Following feedback from Eddy Merckx that a pure 753 frame was too harsh for certain stages of the Tour de France, Reynolds produced a 653 tubeset which combined 753 stays with 531 main tubes and forks. The 531 used was a thinner gauge than usual produced specifically for use in the 653 set.
