Choosing the correct size road bike – geometry explained
Shopping for a new bike is an exciting time, right? But, when faced with such a wealth of bikes to choose from, how do you ensure that you get the right size? Choosing the correct size road bike couldn't be easier. As long as you are armed with the right information, of course. Check out our guide to find out what works best for you.
Women-specific bikes
We like to think of all riders as being individuals, and our priority is in making sure that the bike is right for your body shape, size, and personal preference. Consequently, all of our bikes are unisex in design and are fully customisable to achieve a fit that's perfect for you. The crucial element to getting this right is to ensure that the sizing of key components is correct. Most notable of which are the handlebars, handlebar stem and cranks. Specifying a ladies specific saddle is always highly recommended too, of course.
Back to basics
Firstly we should address what exactly is meant when we refer to 'geometry'. In short, it is simply this; geometry encompasses the shape, length, and angles of the tubes that come together to form the frameset.
For example, the image to the right shows each section of the frame and links it to the dimension in the chart below. For instance, an XS frame has a top tube (B) measurement of 52 cms whereas the S has one that is 53.5 cm.
The geometry of a bike affects the position you will find yourself sitting in, how the bike handles and its aerodynamic performance. A racing cyclist, for instance, will prefer a more stretched out position for improved aerodynamics. A mountain biker, on the other hand, needs a more comfortable, upright riding position. One that offers a head-up riding position that enables them to pick their lines and enhances the stability and control of the bike.
