Where is Reynolds tubing made?
BirminghamThe name has been synonymous with the British cycling industry since 1898, and it still manufactures tubing in its Birmingham factory today.
The Reynolds company name stretches as far back as 1841, but it was the end of the 19th century when it moved into the bicycle trade..
Is Titanium stronger than chromoly?
Well-known member. Both have their place, Titanium is 1/3 lighter than Chromoly, it is also stronger than chromoly but more flexible (less Ridgid).
What is a 531 frame?
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.
How is butted tubing made?
After heating to over 1000 C, a hole is pierced through the center to form a very thick-walled tube. The wall thickness and diameter of this tube are then progressively reduced by hot rolling and cold drawing until it is sized for the butting process.
What is Columbus Thron tubing?
Thron is full double butted standard Chromoly (probably just renamed Cromor). 531 is a manganese-molybdenum medium carbon steel. 525 is butted Chromoly (replaced 531). Thron is better than Aelle and Gara because those tube sets were constant thickness.
Can you mig weld 4130 chromoly?
4130 chrome-moly can be welded with the TIG or MIG process. This filler metal is capable of producing welds that approximate the strength of the 4130. …
What is the strongest metal in the universe?
tungstenIn terms of tensile strength, tungsten is the strongest out of any natural metal (142,000 psi). But in terms of impact strength, tungsten is weak — it’s a brittle metal that’s known to shatter on impact. Titanium, on the other hand, has a tensile strength of 63,000 psi.
How long do titanium frames last?
20 yearsMostly because titanium’s longevity means you’ll still be riding it in 20 years. Riding titanium frames is a real pleasure.
What type of steel is used in bicycles?
American SAE 4130 steelA popular quality steel for bicycle frames is American SAE 4130 steel, better known as “chrome molybdenum,” and referred to as “chromoly” or “chrome-moly.” And, there are plenty of other impressive alloys offered by tubing suppliers such as Columbus, Reynolds, Tange and True Temper.
What is Reynolds 520 chromoly?
520 is the proprietary designation for a range of butted frame tubes made by Reynolds using a chromium molybdenum steel alloy similar to the AISI 4130 standard. Other manufacturers also make butted frame tubes of AISI 4130 chromium molybdenum alloy.
Is stainless a 4130?
Key points: Stainless steels are defined as low-carbon steels with at least 10% chromium with or without other alloying elements. | AISI 4130 alloy steel has properties better than or similar to aircraft-grade stainless steels. | Alloy steels are less expensive and more-easily machined than standard stainless grades.
What is 4130 steel used for?
Applications of 4130 Steel Manufacturing equipment for bearings, vehicle parts, and gears. Rock crushing machinery. Resistance welding products. Drill bits and taps.
What is the strongest thing in earth?
Graphene. Topping the list, graphene is the strongest materials known to humans.
What does 4130 mean?
So in long form, 4130 means an alloy steel with chromium and molybdenum that has a carbon content of 0.3%. One thing to mention about the word “alloy” is that it’s more of broad term explaining the metal material is made of two parts. For example, you might find aluminum alloy for some parts of your bike.
What is the best steel bike frame?

How much do titanium bikes weigh?
Generally, a high-end titanium road frame built stout enough to ride well weighs in at around 1,150 grams.
What is Columbus Steel?
Columbus Tubi is a manufacturer of steel tubing used in bicycle frames, located in Settala, in the Province of Milan. The company was founded in 1919 by A.L. Colombo and was taken over by Colombo’s youngest son, Antonio, in 1977. It is now a division of Gruppo SPA, which also owns the bicycle manufacturer Cinelli.
How do you identify Reynolds 531?
On a seat tube, the thicker butted section is only at the bottom, so the post is inserted into the “thin” cross section of the tube. The ends of most Reynolds tubes were stamped: This is usually most evident on the steer tube, but it sometimes can be discerned on other tubes as well.
