A well-maintained bicycle expresses gratitude to its owner by steering clear of traffic, chirpily ringing its bell, and shooting rainbows from its reflectors at approaching bike burglars. Cruise the color spectrum with today's Groupon: for $30, you get a comprehensive bike tune-up at Chain Reaction Cycles, located in High Point Town Center in Prattville (a $65 value).

Chain Reaction's fully trained technicians groom the weathered gears of rundown road steeds, pampering them with high-quality greases, lubes, and polishes for further asphalt adventures and blazings of bike trails. The bicycle tune-up employs a meticulous 12-point check system to revitalize cycles' bodies and spirits, making them feel young enough to pop wheelies in front of 1870s penny-farthings. Boastful bicyclists and jealous unicyclists can tread over to the sidebar for a full list of services included with the tune-up. This deal isn't valid for additional bike parts.
