What To Expect

Denver SICI and Retul Certified Bike Fitter



Depending on your chosen fit, please allow 1.5 to 3 hours for the fit process. You will be given an estimate of the length of the fit process when scheduling the fit.


Fit Process

  • Examine the bike’s existing rider contact points and components. Wear patterns can reveal inefficiencies.
  • Rider History And Goals. Interview the rider to review injuries/discomfort, exercise and stretching routines, athletic history, cycling goals and objectives. Non-cycling specific issues are also discussed as they can impact bike fit.
  • Review foot structure and how it impacts knee and hip tracking.
  • Cleat/Pedal interface adjustment.  This may include fore-aft, stance width, and internal/external rotation, fore foot varus/valgus shimming and shimming for leg length discrepancies.
  • Saddle assessment. Evaluate proper saddle width, shape and position.
  • Evaluate flexibility to determine the impact on position, power production, alignment and comfort.
  • Riding position evaluation. Evaluation of body movement patterns prior to adjustments.
  • Positional optimization. Systematic position changes under a dynamic load to optimize performance and comfort.
  • Cycling posture evaluation and recommendations are given to reinforce any changes needed to correct cycling posture and technique.
  • Determine final bike position. Test positional stability under dynamic efforts to validate results.
  • Document final position and recommendations. Provide dimensions for bike contact points.

What To Bring

  • Your bike (If performing an existing bike fit)
  • Cycling clothing. Please wear form fitting lycra cycling shorts and short sleeve or sleeveless jersey. Form fitting cycling clothing will allow for proper evaluation of legs, arms and back position during the fit.
  • Cycling shoes. Please bring orthotics/custom insoles if typically used while riding.
  • Pedals.  This is very important.  Please bring the pedals that match your shoes. If you are bringing new pedals or shoes, cleats will be positioned during the fit process.
  • Water bottle.  You will spend quite a bit of time on the bike during the fit process so hydration is important.
  • Gloves. If typically worn while riding.
  • Helmet. Only needed if aero helmet is used for Time Trial or Triathlons. 

Changes To Bike And Possible Additional Charges

Depending on your fit needs additional or different components and gear may be required to achieve the optimal bike fit. Items that commonly need to be changed during a fit are:

Pedal Cleats - Severely worn or damaged pedal cleats can jeopardize the fit process as well as lead to injury. Cleats may need to be replaced to achieve a proper fit.

Insoles - Depending on the structure of your foot, supportive insoles may be required to provide comfort, efficiency and proper knee tracking.

Shoes - Proper fitting cycling shoes are very important to comfort, endurance and power transfer while on the bike. Improperly sized shoes is a common issue with cyclist.

Stems - This is a common change in order to achieve proper reach on the bike. 

Saddles – The saddle is a major part of achieving your optimal bike fit. The saddle will be evaluated and may need to be changed if it is not the proper size and style for your body.

Handlebars/Aero bars - We may need to change your handlebars due to shoulder width, desired reach, hand comfort and brake and shift control.

Seat post - A possible seat post swap may be needed to achieve proper saddle position and knee fore/aft position.

Wedges - We may need to install wedges under your shoe insoles or cleats. This small change can have a big impact on your fit. 

Shims – In some instances leg-length discrepancies may require shimming.


Labor performed after a fit is an additional charge.  This includes changing handlebars, re-taping bars, new brake or shifter cables required by changed handlebar/stem position, etc.
