Ill-fitting accessories can be dangerous, as too-tight ties can cause strangulation and too-loose shoes can cause regular humans to turn into clowns. Match your limbs to your wheels with today's Groupon: for $29, you get a custom bike fitting at Cránk (a $60 value). Appointments for bike fittings are available from 10 a.m. to 5 p.m. every Monday–Saturday.

With a full battery of gear and services, an enthusiastic staff, and cups of Spella coffee at the ready for clientele, Cránk enables cyclists to roll around with ease. Bike-fitting appointments aim to calibrate bikes' geometries to riders' anatomies, adjusting saddles, pedals, handlebars, shifter placement, and all other necessary components to maximize comfort and functionality. Fit is tailored to each individual's unique build, goals, and bike usage, preventing future injuries and helping the torso maintain the optimal posture for racing ostriches to the nearest yoga class.

To prove their devotion to customer satisfaction and quality workmanship, Cránk team members offer a one-year guarantee with adjustments if needed. Any replacement parts required or suggested during fittings can be purchased at a 20% discount, and 30 minutes of replacement labor is free.
