The cycling industry tends to overthink just about everything, but Tacx's Antares Training Rollers are a refreshing exception to this blight of over-engineering. The Antares are straight-up rollers: easy to retract for storage, easy to transport to races, and easy to set up and get spinning on. The only bit of special engineering is the conical shape of the rollers themselves, which helps to coach our tires into the center so we don't ride off the edge while we're zoning out to some trainer tunes.
