*Asymmetrical chainstays provide a longer chainstay on the right side (drive side) for reduced weight and increased stiffness. The shorter chainstay on the left side (non-driveside) allows room for disc brake calipers. Due to the asymmetry of the chainstay layout, clearance between the tires and the chainstays can appear different from left to right side. 

**Electronic configuration designed specifically for use with seatpost integrated batteries. Electronic configuration includes Shimano Di2 and SRAM eTap.
