Simple, straightforward, and streamlined in an efficiency-first manner. The Aire ST combines the wide-range gearing of mountain bikes with the lightweight efficiency of road bikes, making this sport fitness bike one of the most sensible in Haro's lineup. Need a bike to just be a 'bike' without compartmentalizing itself into a specific, indecipherable niche? Look no further, the Aeras is a bike before anything else, and there's nothing wrong with that at all.
