Improved Comfort / Better Performance

Investing in a professional bike fitting is critical to getting the most out of your cycling experience. Each cyclist, from first time novice to professional racer, will benefit from proper positioning, optimizing comfort, and efficiency. At Gerk’s, we specialize in the Body Geometry Fit method, developed by Specialized and the Boulder Center for Sports Medicine. 


Dial in your position with greater detail using real time motion capture. This is included in our Gerk's Bike Fit package.



(Aero/Tri Bikes $350)

The Gerk's Bike Fit is our premier fitting package. This service includes a physical assessment, flexibility testing and general strength testing. We assess all contact points of the bicycle (foot/pedal, saddle and handlebars). A typical Gerk's Fit takes but is not limited to 2-3 hours. 


$125 Hourly

Unsure of your exact needs? We recommend booking hourly Studio Time. This may include new bike sizing, saddle demos, cleat installation, adjustments or general tweaks to your current set-up. 


  • We offer a 24 hour cancellation policy. If you cancel your appointment within 24 hours of the scheduled time, we charge a $50 fee.
  • Please arrive with a clean, functioning bike. We do not service or clean bicycles in the studio. 
  • Please come prepared to your fit appointment with all your usual riding equipment including a clean riding outfit, shoes and helmet. If you have any fit related parts (the touch points of the bike) you wish to install, please bring them. A Bike Fit is the ideal time to change out an old saddle, cleats, worn bar tape, grips, shoes and insoles.
  • If your bike uses proprietary or integrated parts such as a one-piece Handlebar/Stem, understand that in most cases, replacing these parts will need to go through the manufacturer. 
  • If you are bringing a newly purchased bike, be sure to bring with you any small parts or accessories the bike may have come with.
