Product Features

A photo of the Women's Mountain Bike Shorts ST100 in use

Women's Mountain Bike Shorts ST100 is designed for getting away from it all on your first mountain bike tours. Work out and have fun in the outdoors.

The ST 100 shorts, which have a foam pad designed especially for women, can be worn with shorts or alone. The stretch fabric and elasticated hems and waist keep the shorty in place when pedaling.

Seat comfort

The foam pad is specially designed to fit a woman's body.

Freedom of movement

Forget you're wearing it: close-fitting cut and stretch fabric.


Feel supported by the stretch fabric and elastics (waist and thighs).

Para iniciación va perfecto, pero para realizar grandes salidas en bici recomendaria alguno de gama superior.

Bonjour Lucie 
Je vous remercie d'avoir pris le temps de déposer votre avis au sujet du Shorty ST100. Vous avez eu du mal à trouver votre taille à priori. S'agit -il d'un manque d'informations à l'achat sur la correspondance de taille, avez vous essayé le produit en magasin avant l'achat ? 
SI jamais vous souhaitez échanger le produit, vous pouvez vous toujours le faire en vous rendant en magasin. 
Très bonne journée !

Our tip

Our product manager Delphine has a few tips for you: "Need to carry your keys, cards, phone, and tissues? Complete your outfit with a mountain biking jersey, like the ST 100, designed specifically for hitting the trails and with easy-access pockets. As for your hands, don't wait until you fall to find out how important gloves are to mountain biking. Ready? Also, don't forget your helmet and water for staying hydrated".
