Choosing the Right Size Bike

Making sure you choose the correct frame size is of paramount importance when buying a new bike. The correct fitting bike will be more comfortable, more efficient and more fun to ride.

We know that choosing the right sized bike can be a confusing experience, even for the most experienced cyclists – the right size frame depends on the type of bike, your height your riding style and your preference.

This guide gives our customers general advice on choosing the right sized bike. It is a guide only and we always recommend visiting our store or contacting one of the experts in our sales team, if in doubt about the size bike you need.




Different types of bikes are sized in different ways. A 58cm road bike will be quite a different size to a 58cm time trial bike – so it’s important you look at the sizing chart for the type of bike that you are purchasing.

Road, triathlon and time-trial bikes are the most important to size correctly. The reach can determine feel and the frame size required, stand over height is not as important.

The type or style of riding that you do will also affect which size you need. For example a mountain biker that wants to ride more aggressively and would like a more manoeuvrable bike may prefer a size smaller than they would normally take. Likewise a cross country racer that is looking for a flatter and speedier mountain bike may prefer a size larger than they would normally take. Basically there is no right or wrong when it comes to size – choosing the right bike does come down to personal preference and what you feel is comfortable and right for the riding that you do.

Remember, our sizing charts will provide accurate advice for the majority of cyclists, but for the best sizing advice we always recommend visiting our store where you can physically try out the bikes in the flesh or contact one of the experts in our sales team who will be delighted to discuss your individual sizing requirements.
