It is very important to get the right sized bicycle to suit your height and also to adjust the set up in order to maximise comfort and efficiency to enhance your cycling experience. At Cyclerama, this is something we take very seriously, and will do everything possible to help you find that "perfect" position on the bike.

If you can't make it in to the store for assistance, here is some helpful tips that will get you off a good start:

1. Set Saddle Height

Put on the shoes you intend to ride with, then place your RH pedal (drive side) at the 5 o'clock position of the stroke. Your crank should be in alignment with the seat tube of the frame and the lower pedal should represent the longest distance possible from the saddle. Sit on the saddle and ensure that your hips are level, place your heal on the RH pedal. You should aim to have a full straight leg extension with the heal on the pedal. Raise or lower saddle height accordingly to achieve this position.

The idea behind this simple saddle height set up procedure is to quickly adjust the seat to ensure that the rider is using full use of their leg muscles without over extending. When the rider is then pedalling normally, you should aim for about a 30 degree bend in the knee at the 6 o'clock (lowest) position of the stroke.

2. Set Saddle Fore/Aft Position

After determining the correct saddle height and leg extension, sit on the bicycle and rotate the crank so that the pedals are at 3 and 9 o’clock. When viewed from the side, the front of the knee should line up over the axle of the pedal. Adjust the seat forward or back on the seat post to achieve this position.

If the rider is using shoes and cleats, first adjust the cleats so that the ball of the foot is aligned with or slightly in front of the pedal axle.

3. Determine Top Tube/Stem Length Combination

Place your hands in the drop position or on the tops of the brake levers (brake hoods), the middle section of the handlebar should obscure the front wheel’s hub from the rider’s view. You may need to purchase a shorter or longer stem in order to suit your upper body / arm length. Please consult the staff at Cyclerama for more help with your stem options.

Important Note: The above information is a basic industry guide for a road set up. If you are in need of a more serious set up or are experiencing any discomfort when cycling, Cyclerama recommends you seek professional advice from a Physiotherapist specialising in bicycle set up.
