Frequently Asked Questions (FAQs)

1. Is alloy good for bikes?

Aluminium frames historically had a reputation for being uncomfortable, due to the relative stiffness of the material and lack of shock absorption, but the latest frame building techniques, as well the trend towards wider tyres on road bikes, mean many alloy bikes offer a much-improved ride quality.

2. Is alloy a good metal for bikes?

Alloys of steel are the traditional frame material, but the use of aluminum is starting to overtake steel even on entry level bikes. Manufacturers of aluminum frames have evolved their designs to be very durable and with an excellent stiffness-to-weight ratio.

3. What is an alloy mountain bike?

In reference to bicycle frames, "alloy" means aluminum alloy, unless the description includes another type of material. Alloys are metals with other elements added to improve properties like strength or stiffness. Alloy frames are a relatively recent introduction to the world of bicycling.

4. Is steel or alloy bike frame better?

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.
