Ride like it's the weekend all week long! Showcasing the Shimano STEPS system, the sporty Opus WKND does triple duty on commutes, workouts and fun rides. The light, hydroformed alloy frame has the stiffness to react instantly to pedal input. Result — an uncannily responsive ride. The STEPS system's downtube battery, concealed cables and aero wheels also make the WKND look as fast as it feels. Saddle up and never wait for the weekend again!
