Most road bikes come in two styles – racing road bikes (long in the top tube and low at the front for faster riding) and sportive road bikes (which tend to have shorter top tubes and higher front ends for extra comfort). In recent years there's also been a rise in cyclocross bikes, which are for more casual off road rides, and that’s led to the creation of adventure road bikes – a lightweight, drop-bar bike for a mix of terrains, roads and trails. For more information on road bikes and adventure road bikes visit our buying guide.

Women's road bike sizes

Many bikes are designed with the female form in mind. So they accommodate a shorter reach, narrower shoulders and smaller hands. But there’s absolutely no reason why a woman can’t ride a unisex or male bike, so don’t restrict yourself – just make sure you test ride it first.

How are road bikes measured?

The measurement shown is the distance (in cm) from the centre of the bottom bracket to the top of the seat tube (centre of the top of seat tube). However, some manufacturers measure their bikes slightly differently. Some will measure centre of the BB to the top of the top tube (centre to top) or centre of the BB to the centre of the top tube (centre to centre). And bear in mind that a lot of road bikes have sloping top tubes so the measurements can alter – these are often sized S, M, L and XL.
