Sizing Guide

Sizing Guide

What to measure?

In order to size a bike correctly you should consider your height and inside leg measurement along with your riding style and the type of bike.

Measuring your height is best done by standing upright against a wall with your legs together (shoes off) and shoulders back. Place a pencil on top of your head, holding it parallel to the floor and mark the wall. You can now measure your height easily against the wall.

Your inside leg measurement is taken from the floor (again, no shoes) to your crotch. Stand with your legs roughly shoulder width apart against a wall, then take your inside leg measurement. It is probably easier to get someone to do this for you.

Personal choice does play a factor

Bikes are designed to have their saddles raised. That is to have some of the seat post showing. The amount riders wish to raise or lower their saddles is a matter of personal choice. Some riders like the saddle to be higher than the handle bars which means their hands are low when riding, giving them an aerodynamic position. Others may prefer or can only ride ride with their hands around the level of the saddle height, giving a more upright position.

Your measurements, flexibility, age, confidence, riding style, new bicycle choice will play a part in sizing correctly. For a general guide follow our chart below. Please remember that these are only guidelines and personal opinions may differ. We are always happy to discuss frame sizes with you - please contact us.

Off-Road MTB

When riding off-road it is important to have a slightly smaller frame than you would for normal road riding. This is for 2 reasons, firstly to increase the amount of clearance you have over the crossbar to a minimum of 3 inches and secondly, a smaller frame will handle better over more challenging terrain. This will put you in a slightly more forward position with seat-post height extended.
