Bicycle Frames Explained

1. Why are frames important?

   A frame is effectively the chassis of your bike. Many enthusiasts buy a frame then choose their ideal components to build a bike. Mountain bike frames are usually sold without a fork because most riders want to choose a suspension fork separately. Road bike frames usually come as a frame and fork designed to work together.

2. How do I choose a frame?

   Frame design and construction varies enormously. Aluminium dominates the lower price categories with carbon increasingly dominating as prices rise. Top quality steel frames still have their fans because they usually exhibit a more forgiving ride feel than aluminium or carbon. Lightweight titanium frames are popular in higher price categories because of their perceived resilience.

3. How do I choose the right size frame?

   Listed frame sizing varies a lot between manufacturers, with some opting for a simplistic 'S, M, L or XL' description and others quoting the seat tube length. Bear in mind that it's often the top tube reach that's more crucial to achieving a perfect fit. Mountain bike and road frames differ in size because the reach to the handlebar is different and you need more standover room on an MTB.
