Tips for choosing the right frame size

Consider riding position and intended use

A sporty gravel bike is often ridden with a more compact riding position than a city bike designed for comfort. If you prefer a sporty riding style, a slightly smaller frame can provide more agility. For relaxed rides or longer tours, a more upright riding position is ideal.

Understanding differences between frame sizes

Not every manufacturer measures frame sizes in the same way: mountain bike frames are often specified in centimeters, while road bikes commonly use standard S, M and L sizes. corratec combines both systems to make choosing the right size as straightforward as possible.

Choosing the right frame size - FAQs
How do I measure my height correctly?
Stand barefoot and upright against a wall, look straight ahead and measure the distance from the floor to the top of your head. For an even more accurate measurement, place a book on your head and use the lower edge of the book as the upper measuring point.
What should I do if I am between two frame sizes?
If you prefer a sporty riding style, choose the smaller size for greater agility and a more forward-leaning position. For more comfort, the larger frame size is recommended. A larger frame is particularly suitable for a touring-oriented riding style.
Can I adjust my bike after purchase?
Yes. With the right stem, saddle or seatpost, the bike can be fine-tuned to fit you even better. Spacers, for example, can make a forward-leaning riding position more upright and allow the setup to be adapted to changing needs.
Does corratec offer advice on choosing the right frame size?
Yes – both online and in person at corratec partner dealers. If you are unsure, the corratec team will be happy to help you online, by phone or at a specialist retailer. Take the opportunity for a test ride or arrange a consultation with a corratec dealer near you.
