Spinback celebrates the second annual International Indoor Cycling Day which is dedicated to celebrating all things about being on the bikes - the joy, the challenge, the music, the camaraderie, the community, the burn, and all that good stuff. Spinback will once again open both studios to the Shanghai community and offer free classes to showcase indoor cycling, what it means to work those watts, and have fun on the bikes. A day full of fun, sweat, and SWAG from sponsors.
