4130 Chromoly Steel Bike Frame

The now commonly used moniker chromoly indicates a steel alloy that includes just enough chromium the chrom part and molybdenum the moly part to be.

4130 chromoly steel bike frame.

4130 chromoly is one of those things that most bmxers are familiar with because well a good portion of your bike from your frame to fork bars and cranks are made from this material. Chromoly 4130 steel frame all our frames which is 4130 chromoly steel recognized as one of the most high quality materials used in bicycle manufacturing. Chromoly steel enables all of this. Surly bikes are made with 4130 tubing.

Chromo as it s most commonly called is very durable and sure to make your bicycle last a long time. Because of it s strength the tubing used for a chromoly bicycle frame is thinner you don t need as much material as you do with low quality steel. We build with 4130 but there are other grades of steel and not all are created equal. Stack it up in the bike pile.

They re durable and. High tensile steel is also light but it s much weaker than 4130 chromoly so builders have to use a lot more of it to achieve the same strength. Among the most popular bicycle frame materials as of 2013 is 4130 chrome moly steel but its dominance in the marketplace has not stifled innovation in other alloys. Toss it in the back of a truck in the outback.

Chromoly is a strong steel so strong that it is often used to make race car roll cages. You are going to hate this answer as i throw it into the gray soup of bicycle metallurgy. Most cycling steel alloys are based on 4130 chromoly. In addition to sourcing our chromoly steel from us manufacturers detroit bikes produces our usc line of bike frames right in our detroit factory where we also paint assemble wheel build and package our products.

If you re looking for a high quality urban commuter bike consider one of our chromoly steel bikes. However steel is density challenged frames are usually heavier than their aluminium or titanium equivalents. Titanium an extremely dense and solid metal is a step up from steel in terms of stiffness weight damping and. It will be fine.

But what exactly does 4130 mean. Cheap bikes often use straight gauge high tensile steel. Steel will rust if neglected though frames can be treated and manufacturers such as reynolds produce stainless tubing that largely negates this problem. Derby rated as we used to say.
