How to Buy the Right Size Bike Frame

The main factors to take into consideration when choosing a bike frame are:

* What size will you need?

* Who are you buying the bike frame for?

* Is it the correct weight?

Size

In order to work out the right size bike frame you will need, you must start with an inside leg measurement. This will give you an accurate measurement for your 'stand over height'.

Stand over height is the distance between a rider's crotch and the horizontal top tube of the frame. It is important that the measurement is exact as feet slipping from the pedals or a slip forward in a fall could be painful for a rider if they come in contact with the tube.

A measurement of your height is also needed in order for you to choose the right frame. The chart below allows you to combine your height and inner leg measurements to help you choose the right size frame for you.

Frame sizes increase depending on the type of bike:

* 2cm increments for road bikes

* 2 inches for mountain bikes

Who Are You Buying the Frame for?

As you can see from the frame sizing guides, the size of the frame varies according to gender and age. It is important that a child is measured to the exact centimetre as they are more prone to accidents than adults.

Beginners' bikes are important for first time riders and children. Saddles can be adjusted to add extra height as a child grows.

How to Choose the Correct Reach

As the frame size increases, the top tube length and head tube length also enlarge to keep the bike stable and in proportion.

If your measurements of height and inside leg place you between sizes, your upper body is the tie-breaker; the reach to the handle bars may be affected. This could result in a loss of steering control.

To determine whether you have long or short reach you must find your Ape Index. This is calculated by:

* Measuring your arm span - from left middle finger tip to right middle finger tip.

* Subtract your height from your arm span.

If your arm span is greater than your height then choose the bigger frame.

If your arm span is smaller than your height then the smaller frame is what you need.

Weight

Weight needs to be taken into account when choosing the frame as you must be strong enough to ride the bike uphill as well as on flat surfaces. The lighter the frame , the easier it will be to propel the bike. A few grams make a big difference, especially if you travel over longer distances.

About the Frame

The angle of the vertical tubing frame on a town bike provides the stability to ride with one hand, which the Dutch often do whilst holding a mobile phone with the other. Because the frame is the backbone of any bike, the material it is made from fundamentally affects the performance.

General town bikes offer the choice of steel or aluminium frames within its overall range. Good bikes should have decals, or markings, which verify the type of metal, such as Reynolds 853 steel, somewhere on the tubing.

Steel offers excellent ride quality and durability. It is easily repaired and affordable but tends to be heavy when low-quality tubing is used and most types can rust. A popular quality steel for bicycle frames is chrome molybdenum, referred to as ''chromoly'' or ''chrome-moly.'' There are plenty of other impressive alloys offered by tubing suppliers such as Columbus, Reynolds, Tange and True Temper - known for their combination of responsiveness and comfort.

Aluminium is now the most popular of frame materials. New aluminium alloys, tubing enhancements and improved construction techniques allow the frames to absorb shock better than ever while still offering a lively ride, thanks to being the lightest frame material. Nor does it rust. Look for 6061 and 7005 tubing, referring to alloys such as magnesium, silicon and zinc which impart strength.
