Sports Plus, Denver

On historical Old South Gaylord Street, you can see the seasons change by looking at the leaves on the trees or the stock in Gary and Mark's shop, open since 1980. In winter months, the dual owners of Sports Plus deal in new and high-quality consignment skis, snowshoes, and hockey gear, whereas summer months bring out inline skating, cycling golf, and tennis gear. The shop also saddles up adults and children on hybrid, mountain, road, and fixed-gear cycles in makes such as Raleigh, Diamondback, and Sun. The sharp-eyed staffers also tune and repair, readying each used bike before a sale and keeping rides faster than the Flash’s treadmill with onsite tune-ups and flat fixes. Though not included with this Groupon, a menu of services helps sports enthusiasts evolve into stars; it includes ski repairs, skate sharpening, racket restringing, and more.
