Bike Size FAQ
Choosing the right sized bike depends on a few things: the type of bike, your height, your arm and leg length (in proportion to your height), your confidence and your riding style.
Having the right size bike means that you're comfortable and will be in control.
For a bike with a crossbar you should be able to stand over the top tube with around two inches of clearance.
Typically the ball of your foot (or feet) when you are sat on the saddle should just reach the floor, you shouldn't be on tip toes or lean over far to one side. Many riders prefer to have their feet flatter on the ground and that's totally fine simply adjust your saddle to a lower height.
If you choose a model with a suspension seatpost please be aware that the saddle won't go as close to the frame as a standard seatpost.
How is the frame size measured?
Most bike frame sizes are measured from the centre of the bottom bracket to the top of the seat clamp but can vary between brands. Please don't assume a size in one brand is the same as another and even model year sizing can vary.
How do I choose the correct frame size?
Choosing the right sized bike depends on a few things: the type of bike, your height and your riding style. A correctly fitted bike will be more comfortable, more efficient and more fun to ride allowing you to go further for longer.
What if I am between two sizes?
It is very common for a size chart to recommend two frame sizes for your height. If you are between sizes based on your height the fit is then determined by the reach which is the distance to the handlebars when sat on the bike. If you have a longer torso and arms the larger of the two frames maybe a better fit and vice versa for a shorter torso or arms.
How high should my saddle be?
Correct saddle height is important not only for comfort but for pedalling efficiency too. Here is a simple method to set the correct saddle height:
- Whilst stood next to the bike, set the saddle to the height of your hip bone. Ensure the saddle is not extended past the minimum insertion mark on the seat post.
- Using a wall, table, chair or friend holding the bike for you, sit on it with both feet on the pedals. Rotate the pedals back so that the crank arms are at 12 and 6 o clock. On the lowest pedal move your foot forward so just your heel is on the pedal. In this position you should aim for your leg to be straight but not locked out.
- Once you have set your saddle height place your foot on the pedal at 6 o clock in your normal riding position. At this point your leg should have a bend at the knee.
