Wednesday sits in the middle of Surly's Trail category, but donât let that fool you into thinking thatâs its only use. With Wednesday, we borrowed elements from some of our Trail and Touring models to create a versatile fat tire trail bike that can truly handle anything you want to attempt.If you do an equal amount of off-road touring as you do hitting trails, Wednesdayâs ability to play both parts equally will suit you well. Or, if youâre looking for a fat bike and donât need the fattest tires on the market, Wednesdayâs 26 x 4.6� tyre clearance is just the ticket.
