Aeras starts with a Ventus Series hybrid frame that features Rider Optimized Geometry specifically designed to assure a proper and comfortable fit. All Ventus Series models are ideally suited to a wide range of uses including commuting, fitness riding, recreational riding and good old fashioned errand running. Unlike its Solum Series counterparts, Aeras uses a rigid steel fork with disc mounts to increase pedal efficiency by preventing energy loss associated with excess fork movement. Aeras comes complete with a Shimano 21 speed drive train that includes EZ Fire shifters. Its wheelset is made from Pivit alloy 28h disc hubs laced to 700c alloy double wall rims and all weather stopping is made possible thanks to a pair of Tektro Aries mechanical disc brakes.
