Why it pays to compare

Mountain Bikes are complicated machines.

They have parts from hundreds of different manufacturers, come in all shapes and sizes (and colours) and are all suited for different purposes. Choosing the right new (or used) Mountain Bike is a complicated, confusing and highly emotional (think buying a new car- the shiny red one is the best choice right?).

Comparing mountain bikes helps bring a bit of logic and reason into the decision process. Not only will comparing mountain bikes save you money, but you'll also find the bike most suitable to you, your riding style and your budget. Plus, when you do hit the Buy Now button, you'll have the confidence you're choosing the perfect bike for you.

It's easy to get carried away by the most rad looking frame, with the coolest paint job and the most aggressive new geometry, but the components are one of the most important things to consider.

A wise Mountain biker

What to compare

Components

It's essential to know which components make up a bike. From there you can compare the differences, such as build quality, performance, features, weight and price. This takes some of the guesswork out of buying a mountain bike.

Here are the components that have the biggest impact on your ride. You should be paying particular attention to these:

  • Fork
  • Shock
  • Drivetrain (Derailleur, shifter, cranks, chain etc.)
  • Brakeset
  • Wheels
Price

Ultimately, for most of us, price is the deciding factor and you want to get the most bang for your buck. Comparing the price of mountain bikes, along with which components you're getting, helps you determine what you're actually paying for. Are you spending your hard-earned dollars on a quality bike frame, with quality components and a solid warranty? Or are you simply paying for a brand name?

Reviews

Nothing is more helpful than what real people think about a bike. It's the next best thing to riding one yourself. Reviews give you a real insight into how a bike actually rides, instead of just what the numbers seem to say about it.

Warranties

Different bike companies have different warranties. It's important to compare the length of these warranties, what they'll cover and who's covered.
