UNISEX FRAME
With a very marked slope on the top tube and a wide range of sizes (from XS:1.45m to XL:2.00m) The ST 100 mountain bike frame is UNISEX.
The ST 100 mountain bike exists with the same frame in a WOMEN'S version: fitted seat, narrower handlebar, shorter stem, fork with a more flexible spring, and brake levers that are closer together.
As a WOMAN, if you choose the MEN'S model, we recommend at least purchasing the WOMEN'S SPORT 500 saddle which is fitted to the female form.
