Companies such as Peugeot used huge quantities of this tubing. Today, Reynolds continues to produce high-quality steel tubing for bicycles, including the popular 853 and 953 tubing. Reynolds brochure from early 80's. The friction factor for straight tubing (fST) in laminar flow is given by This was a quality tubing subjected to special drawing treatment to improve the structure of the steel and to reduce possibilities of fatigue cracks. Mid-range CX and road bikes are where it's at. a steal for a Zurich(depending on condition). The internal diameter of the tube varies so that the tube is thicker at the joints, Models of Reynolds Tubing: Reynolds 520. Vitus 971 tubing is shown to have ultimate psi strength in excess of Reynolds 531, and as you can see from the above chart is significantly stronger than lower end steel tubing of this era. Regardless of whether someone preferred Campagnolo, Simplex, Huret, Would Reynolds 725 be noticeably different to 853? Are the numbered Reynolds grades noticeably better than basic cromoly? Posted : 10/07/2015 10:31 pm The chart represents friction factor as a function of Reynolds number and the ratio between internal pipe roughness and pipe diameter, or relative roughness, ε/D. The TIG welded part of the tube still benefits from the air-hardening feature that results in a fine grain structure within the heat-affected zone. Reynolds 853. Unlike Reynolds, whose famous 531 bicycle tubing was a manganese-molybenum alloy, Columbus primarily used chrome-moly steel. 439 Views bishbashbosh. The text panel will appear.

Columbus pulled out almost all the stops to make a lightweight 0. Butting refers to the tube being drawn thinner at the middle and left thicker at the ends for brazing/welding purposes. Although steel frames are no longer as popular as they once were, many cyclists still appreciate the ride Going back to my time, (50s /60s) the seat tube had an outside diameter of 1. D. The interaction between the alloys results in a fine grain structure that forms with air-cooling without the traditional “quenching” (fast cooling in water or oil) process. These are double-butted tubes, with different thicknesses at each end. Reynolds has always used numbers: 531, for example is a precise description of the ratios Using an industry standard alloy with mechanical properties similar to our famous 753 brand, Reynolds mandrel butt and heat-treat this alloy so that thinner walls can be used compared to non-heat-treated steels.
