Choosing your bike size by height
Choosing the right frame size is the most important step when buying a bike: a bike that fits is comfortable, handles well and avoids aches and pains. The table below summarises Polygon's recommendations for the models Spinlab distributes.

When you are between two sizes
- Choose the smaller size if you like a nimble, agile bike; choose the larger size if you prefer stability on long rides.
- Riders with long legs relative to their torso usually suit the larger size; a long torso with shorter legs usually suits the smaller size.
- Saddle height, stem length and handlebar position can be fine-tuned once you have the right frame size.
How to measure your height accurately
- Stand straight without shoes, back and heels against a wall; place a flat object on your head and mark the wall.
- Also measure your inseam (from the floor to the crotch) so our staff can recommend the size and saddle height more precisely.
Try before you buy
The size chart is a starting point; how the bike actually feels matters most. Visit your nearest Spinlab dealer to sit on the bike and have it adjusted to fit you.
