Frequently Asked Questions (FAQs)

1. Are aluminium mountain bikes good?

Nonetheless, aluminium is a more brittle and weaker material than steel, and as such frames tend to be slightly overbuilt to make frames stronger and give a larger safety margin. Frames are designed so that stresses are low enough that in normal loading it will not reach its fatigue life within its usage lifetime.

2. Are aluminium bikes good?

While aluminium frames offer an impressive balance of strength, stiffness and low weight, aluminium alloys can be prone to long-term fatigue, unlike steel and titanium. However, aluminium frames tend to be less susceptible to crash or accidental damage than carbon frames.

3. How long does an aluminum mountain bike frame last?

Doesn't Last Long Aluminum frames don't last as long as other bike frames do. On average, aluminum frames last for about 6 years, while steel frames have an average lifespan of about 20 years or more. Every time you place some weight on the bike, the frame gives in because aluminum doesn't have fatigue limits.

4. Is aluminum better than steel bikes?

Aluminum frames are generally stiffer than steel, resulting in a harsher ride. When fractions of a second count, track racers prefer that rigidity. But for getting to the store over city streets steel offers a more forgiving ride. No frame material is more durable than steel.
