Trek Women's Specific Design mountain bikes have been designed, crafted and built with a woman?s body in mind. Why? It's all about the fit. WSD bikes do more than maximize your performance and power - they fit like no men's mountain bike can. A unique revamped geometry places you in a riding position that's more natural to the female body, allowing you to generate more power with each pedal stroke. Specially designed components, including a shorter stem and shorter reach brake levers with thinner grips, create the feel you need for quicker climbs, more precise and confident descents, faster sprints and it all adds up to a lot more fun. Whether you're getting fit, competing or just having fun, you'll feel the difference from your hands all the way down to your anatomically supported saddle.
