Cyclocross bikes are built for versatility. Many riders prefer these bikes because they can be ridden on any terrain. The versatility of these bikes is due to their hybrid design -- the frames are light and strong, and the wheels are thin for road surfaces and thick and studded for control on off-road trails and terrains. Cyclocross bikes use different frames from road and mountain bikes, and sizing for these frames is slightly different. A proper frame fit is important to reduce the risk of injury while riding while also improving comfort and riding efficiency. Fortunately, sizing the frame requires easy calculations.
Step 1
Remove your shoes and stand straight up against a wall. Use measuring tape to measure from your heel to the top of your crotch. Record this measurement in centimeters.
Step 2
Multiply your inseam in centimeters by .65. This gives you the approximate standing height of the best cyclocross frame for your body -- frames are measured according to their height in centimeters, which equal their frame size number.
Step 3
Subtract 1 or 2 cm from this measurement. This extra space allows you to comfortably put both feet on the ground in sitting on your cyclocross bike. It improves the comfort of the bike and your control when stopping and starting.
Tips and Warnings
- In most cases, your preferred cyclocross bike size will be slightly smaller than what you ride on a road bike. This lends itself to improved control and efficiency when riding cyclocross.
