Before wintertime hibernation, bicycles forage and fill their inner tubes with enough sustenance to feed training-wheeled cubs come spring, a noble act that often leads to serious exhaustion. Help spin the spokes of life with today's Groupon: for $27, you get a bronze tune-up from RediBike Cycling & Fitness (a $55 value). You can also use your Groupon toward an upgraded tune-up service by paying the difference.

The dedicated, friendly gearheads at RediBike Cycling & Fitness aim to make the bikery the top stop for cycle and triathlon gear. Wheel in downtrodden frames for the thorough bronze tune-up service. The overhaul begins with a thorough cable cleaning and lubing. Surgical adjustments are made to the tension of the brakes, ensuring riders can stop on a dime, pick it up, and buy a Chiclet without ever dismounting. Derailleurs are inspected and rebuffed to transform sticky gears into smooth shifters. The treatment ends with a stem and seat-bolt-post inspection and tire inspection with flat repair. Once complete, in just one or two days, your machine will emerge confident, firm, and fresh, prepared to compete and hungry for asphalt.

This Groupon is not valid for replacement parts.
