Since the Mojo is an all-mountain bike, it makes sense that it has a quick release seatpost binder -- extend the post for proper pedaling efficiency going up and drop it for the gravity fueled ride back down. Should you need a replacement for your Mojo or desire to retrofit one to your Mojo SL, Tranny, or Hakkalügi, this is the part you'll need. The Mojo QR Seat Binder is made of forged aluminum and is available in three finishes -- nickel chrome, anodized red, and anodized blue. 61grams
