More choice for all genders
We believe every rider - regardless of gender, body type, riding style or ability - deserves a great bike. One that gets you excited to hop in the saddle and ride. A bike that makes you want to go faster and further than ever before. A bike that feels like it was made just for you. Because it was. Trek is introducing the new 2020 Domane to give better fits and more options to female and male riders alike. Historically, we've offered smaller frame sizes geared towards women on women's models exclusively. We're now offering smaller sizes and more colourways on every single 2020 Domane SLR, SL. A smaller rider, no matter their gender, can now choose from every model we offer in these performance lines. There is no specific women's offering for these bikes. They're all women's bikes. They're all men's bikes. Why are we doing this? To give more fit and colour options to all riders, regardless of gender or size.
