Women's MTB Size Guide

Women’s MTBs tend to be shorter in length, have narrower handlebars and smaller frame sizes. They also have specific saddles and often have their own colour scheme too. Like other MTBs, these designs are measured in the same way (from the centre of the bottom bracket to the top of the seat tube) but there’s no reason why you shouldn’t try a unisex MTB.

How are MTB's measured?

MTB's are measured from the centre of the bottom bracket (BB) to the top of the seat tube. To give a rider more stand over height, MTB top tubes often slope down and join the seat tube lower than road bikes. So it’s worth taking your inside leg measurement and comparing it to the manufacturers model. Always check the manufacturers measurements or speak to our experienced staff members.
