What is double butted chromoly?

Double butted means the tubes are thicker at the ends where they are joined so they can be light an strong.

What is Reynolds 520 chromoly?

With similar properties to our original 531 brand alloy. For cycling, these are mandrel butted for accurate profiles, and available in a wide range of shapes. The Reynolds “520” range uses the same alloy, made under license for us in Taiwan and subject to the same quality standards. …

What does butted chromoly mean?

Chrome Molybdenum
Chromoly (Chrome Molybdenum) Steel When it is butted and shaped to take off excess weight, it can deliver a fairly light frame that will last through years of hard use. Chromoly is responsive and offers good flex while maintaining its form.

Which is better chromoly or alloy frame?

Chromoly vs Aluminum It’s lighter and stiffer than steel, but it’s also more brittle and easily damaged. Chromoly is slightly heavier than aluminum, but the frame can be thinner and has reduced stiffness, which provides a smoother ride. Aluminum, on the other hand, is more like glass, which breaks before it bends.

Is Titanium stronger than chromoly?

Both have their place, Titanium is 1/3 lighter than Chromoly, it is also stronger than chromoly but more flexible (less Ridgid). So depending on the designer both can be used to their full potential.

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.

Is DOM tubing stronger than chromoly?

From the research I have done, chromoly is generally 20-25% lighter than DOM. The reason for this is only because chromoly is stronger so you can use a thinner wall tubing and have the same strength. It would be interesting to see the difference.

Is chromoly stronger than titanium?

How long will a chromoly bike last?

Chromoly frames are typically overdesigned well above the endurance (fatigue) limit of 0.54 of tensile strength. This means if the welds are properly done, you can expect what we call ‘infinite life’.

What is the strongest thing in earth?

The World’s Strongest Stuff

• Diamond. Unmatched in its ability to resist being scratched, this much-loved gemstone ranks the highest in terms of hardness.
• Graphene.
• Spider silk.
• Carbon/carbon composite.
• Silicon carbide.
• Nickel-based super-alloys.

How long do titanium frames last?

Carbon and titanium bike frames will last the longest with proper care, with some even outlasting their riders. Aluminum and steel bike frames should easily last 6 years but will require regular maintenance to keep them running any longer than 10 years.

What kind of tubes does Reynolds 708-708 have?

708 – 708 was a tube set in Reynolds’ range in the 1980s. It has main tubes with special section. These were not butted, but had 8 flats running along the length of the tube. The rear stays would be 753.

Which is better Reynolds 531 or Reynolds 520?

If you look at a piece of cheap steel tubing you will see the join as a different coloured line running down the tube. For example the old Reynolds 531 and all better tubes from Reynolds are seamless as is their Cr-Mo 520 and 525 (identical except 520 is license built in the Far East) so not all 4130 Cr-Mo is equal.

When did John Reynolds invent the double butted tube?

Reynolds introduced the double-butted tube-set 531 in 1934. The Patent Butted Tube Co., Ltd., the predecessor of the present company, was spun off from John Reynolds’ original company in 1898.

What can Reynolds cycle tubing be used for?

Reynolds 525 range can be used for sports car chassis, suspension units, motorcycle race frames etc. in welded and fillet-brazed structures. The same 0.30% carbon steel chemistry as our 725 range but without the heat-treatment process.
