Put yourself atop some Tacx Antares Rollers this winter and you'll be flying in the spring with more smoothness than a pair of freshly shaven legs. Their 4" drums are made from heavy-duty polymer and have a tapered shape that will help keep you centered on the rollers while you ride. An innovative sliding framework means the Antares is quick to set up and collapses down for easy storage.
