Hi-Ten Steel vs Chromoly Steel – What’s the Difference

Hi-Ten Steel vs Chromoly Steel

When choosing a bike, the frame is an important factor to consider. Two common materials used in bike frame manufacturing are hi-ten steel and chromoly steel. Although they are both steel, key differences affect the bike’s performance. This post dives deep into the differences between hi-ten and chromoly steel to help you decide when to choose a bike.

What is Hi-Ten Steel?

Hi-ten, or high-tensile, is a low-cost, high-strength steel alloy commonly used in entry-level and budget bikes. It is made by mixing carbon and iron and has a lower tensile strength than chromoly steel. The lower tensile strength means that hi-ten steel frames are heavier and tend to flex more on hard rides. Additionally, hi-ten steel is less resilient and has a shorter lifespan than its counterpart.

What is Chromoly Steel?

On the other hand, Chromoly steel is a high-performance alloy made by adding chromium and molybdenum to carbon and iron. Adding these elements increases the tensile strength of the steel, making it stiffer, lighter, and highly responsive. Consequently, chromoly steel frames are more expensive than hi-ten steel frames but offer superior ride quality, durability, and handling. Whether you’re a beginner or a professional cyclist, chromoly steel frames offer excellent value for money.

Differences Between Hi-Ten Steel and Chromoly Steel

The tensile strength is the most significant difference between hi-ten and Chromoly steel. While hi-ten steel has a tensile strength of about 80,000 psi, chromoly steel has a higher strength of about 100,000 psi. This means chromoly steel is less likely to crack, bend, or deform under stress than hi-ten steel. Chromoly steel frames have thinner walls and can be welded more precisely, resulting in a more refined structure.

Strength vs Weight

When choosing a bike frame, the strength-to-weight ratio is critical. Although hi-ten steel frames are strong, they are heavy, making them less responsive and slower on steep climbs. On the other hand, chromoly steel frames are lighter, making them more responsive and better suited for long rides and climbing. Chromoly steel frames offer superior shock absorption, ensuring maximum comfort on bumpy roads.

Final Thoughts

Choosing a bike depends on personal preference, budget, and intended use. Hi-ten steel frames are a good choice if you’re looking for an affordable bike that can handle some riding abuse. However, if you’re looking for a more responsive, durable, and high-performance bike, chromoly steel is the way to go. Although these frames may cost more, they offer excellent value for money in terms of quality, comfort, and durability.


In summary, hi-ten and chromoly steel frames are made from steel, but their strength, weight, and durability are the key difference. While hi-ten steel frames offer a more affordable option, they are heavier and have lower tensile strength than chromoly steel frames. On the other hand, Chromoly steel frames are lightweight, have better shock absorption, and offer superior handling and durability. When choosing a bike frame, consider your budget, preferences, and riding style to make an informed decision that will give you the best experience on the road.
