Ryan's latest addition to his bike family is the 2017 SJ FSR Expert Carbon 6Fattie. What made him choose the 6fattie frame over a 29er or 650b was its ability to use either of these wheel sizes. The bike comes stock with Roval Traverse 650b wheels, 3.0" 2Bliss Ready tires, and a boost setup, so Ryan built a sweet 29er wheelset to add some variety to his mountain bike lifestyle!
