Like a marriage, a bike requires ongoing maintenance to prevent one of its wheels from running off with a unicyclist. Keep all moving parts contented with today's Groupon: for $30, you get a bike tune-up (a $60 value) at East Coast Alpine, redeemable at either of its locations in Boston or Danvers.
East Coast Alpine keeps bikers cycling to the summit of their skill-mountain by tuning two-wheelers to peak condition. Technicians calibrate bikes for safety and a smooth ride by adjusting the brakes, front and rear derailleurs, and cables; physically checking the derailleur hanger, bottom bracket, crankset, hubs, rims, and tires; and testing the bike's gear-jerk reflex using a tiny hammer. Bikologists will also degrease and lubricate all moving, nonbiting parts before cleaning the nonmotorized carriage and truing the rims if needed. After performing the full inspection, the team can recommend further repairs to the owner or prescribe a treatment for handlebar acne.
