The Retrospec Harper Plus Wheelset is one of the most versatile wheelsets available. The super deep-dish wheels boast features that transform any bicycle into a lean, mean, cycling machine. Transform every ride into a silky smooth dream as you ride atop these colorful and durable wheels. The rear wheel has a flip-flop hub with a 16T 1/8” fixed-gear cog and a 16T freewheel cog. Our upgraded Mantra wheelset comes with sealed bearing hubs, which dramatically increases the lifespan of your wheels by keeping dirt and muck out of fragile parts of your bike. Other notable upgrades include the 43mm Stars rims, one accent color spoke, and Kenda Kwest tires. Grab a set of Mantra Wheelsets and get moving.
