Welcome to the men’s road bike size guide, which also applies to cross bikes (road bikes’ more rough-and-ready cousins). Generally speaking, road bikes have skinny tyres, a more “aggressive” frame geometry, and drop handlebars to help you achieve that low, streamlined position. Road bike frames are also traditionally referred to in centimetres as opposed to using small/medium/large sizing. If you are wondering what size road bike you need, the road bike size chart below matches your height to the right road bike frame size.
We have separate guides for women’s road bike sizing and for kids road bike sizing.
Please bear in mind that your height is only a rough guide to bike sizing, so if you have any doubts then don’t hesitate to contact one of our friendly team.
