I had a guy who was in the shop with his mate buying a bike a few weeks ago, a mountain biker who had been sold a $6000 bike at another shop.

He was telling me about his 56cm frame - this guy was 5 foot 6 at best! I asked him if he ever got sore shoulders and back. He said he did, but he thought that was just the price to pay for "feeling aero". I was incredulous that a higher end bike could be SO wrongly fitted.

Unfortunately, this wasn't the first time this has happened and I'm sure it won't be the last! Lots of people are sold the wrong size bike and many of these people end up giving riding away simply because they are so uncomfortable. But at the same time, lots of other people are told they need to pay hundreds of dollars for a professional bike fit, and more to get the components the bike fitter wants to sell them.

So what is the truth? Well I went and spoke to one of our mechanics, you know the one, the guy who lives and breaths bikes, has a shed full of old ones and wears an old cycling cap everywhere he goes, and this is how the conversation went down.


Interview with the guru:
ME:
Why do bikes come in different sizes?

GURU:
Bikes come in different sizes for different size people, and it's what makes them more comfortable and easier to pedal.


ME:
How are bikes measured?

GURU:
Adult bikes are measured by the frame size. As a general rule you do this by measuring the top tube and the seat tube. Children's bikes are usually measured by their wheel diameter.


ME:
How do I determine what size bike to buy?

GURU:
Part of the process of determining what size bike to ride is measuring your height and your in-seam length, or the length of your inner leg.


ME:
How do I determine what size bike to buy my child?

GURU:
What size bike to buy your child is best determined by having them stand over it. They should clear the top bar by at least an inch. However, with children's bikes, you can often go by their age.


ME:
How do I know what size bike to buy for someone else or for myself online?

GURU:
With our experience, we can help you determine the correct size needed if you know the recipient's height and general proportions. The quickest way to do this is to send us an email to sales@cyclingexpress.com or call us on (03) 9738 1633.


ME:
Do I need to buy a woman's bike if I am a woman?

GURU:
No. You don't need to buy a woman's bike just because you are a woman. You do, however, need to have a good fit. Bicycles these days are usually a unisex product. They also come in many sizes. That means you can get a good fit by doing things like ordering your bike with a shorter stem and a more comfortable saddle if you are a women. Again with this one you can contact us for more info. However, if you are five foot or shorter you may need to buy a women's specific bike.
