Function, Ergonomics and Fitting Services with Jerry Gerlich

Just like there is no DNA alike, each bike fitting is unique to the person it is designed for.

Since we all cycle, walk, push, pull, twist, balance, breathe and stabilize differently, each fitting is a new adventure.  Comfortable and efficient cycling requires more than just sitting on a seat, grabbing a bar and turning over the cranks.  An optimal cycling position requires us to have well-supported feet with the appropriate seat and bar positions for comfort, leverage and stability. By having stable, flexible and strong bodies, we can push our physical boundaries with limited detrimental impact. A truly optimized position allows us to look ahead comfortably and breathe deeply while enjoying the ride.

What to expect during the Comprehensive Fitting

  • Pre-fit interview to outline any variables or physical issues causing problems while you ride.   
  • Thorough evaluation of your stability, form and function both on and off the bike(s).
  • Application of unique assessment and cleat/seat/bar adjustment methods with an emphasis on cleat/shoe and saddle/bar optimization as applied by Steve Hogg.
  • Remedial off-the-bike exercises and stretches for increased symmetry, range of motion and coordination.
  • Detailed position records post-fit for future use in setting up different bicycles.

What NOT to expect during the Comprehensive Fitting

  • Diagnosis of injuries or diseases.
  • Chiropractic-type adjustments.
  • Cleaning/tuning/repair services to bicycles in need of attention. (We are not responsible for questionable equipment that fails during a fitting session)

What to expect AFTER the Comprehensive Fitting

New muscular recruitment patterns take time to settle in and feel solid. You are highly encouraged to come in with a 2-3 week window of easy riding after the fitting work to give your muscles and nervous system time to adapt to the changes.  You will most likely experience one or more of the following:

  • New sensations through the whole body as your feet, pelvis, back and hands can wind up in much different positions than when you arrived.
  • Small ring efforts without hills at a heart rate of under 75% max for 2-3 weeks to give your body time to develop the new motor patterns required for the new position.
  • New balance sensations. (Adapting to these new balance sensations will require frequent riding without hard cornering, sprinting, long efforts and fast descents.)
  • Minor aches and pains caused by your body’s previous motor patterns attempting to function with the new position.

What our Bike Fitter expects after the Comprehensive Fitting

  • Your trust that I know what I am doing and that I WILL make improvements to how you feel on the bike.
  • You will commit to this process with me.
  • You will contact me with any questions or concerns as soon as possible.
  • You will follow my instructions and you WILL NOT make any adjustments to your bike without first discussing it with me.
  • You will do your best to follow the off-the-bike recommendations that I give you.

What to Bring

  • Basic Equipment: Bike(s), shoes, fresh cleats if available, any orthotic devices/insoles/foot beds you have, any cleat shims or wedges you currently use, cycling riding kit, all eye wear including prescription glasses, sunglasses, readers and swim goggles, helmet(s), gloves, seat bag with contents, mobile phone and sunscreen to test your new position outside if possible.
  • Accessories: Water bottle for hydration, snacks, money for purchases in our Food for Fitness organic cafĂ©, shock pump, seat mast cutting guide or other tools/spacers/items specific to your bicycle.
  • An Open Mind: You will experience a completely unique approach to bicycle fitting available only in Austin, Texas.

What to Wear

  • Cycling kit, including jersey, bib, shorts, cycling socks, sports bra for women. (Ideally, shoulder, spine and hip assessments are conducted with the jersey off.)
  • Sandals or running shoes for moving around the gym without cycling shoes.
  • Light jacket or sweatshirt for the bike fitting room. (This isn't absolutely necessary, but the room runs cool for exercisers.)
  • Please refrain from wearing cologne, heavily-scented body spray or perfume.


  • The comprehensive fitting fee is $450 for first 3 hours and $150 per hour after that.
  • Setting up a second bike based on the first bike is $200 up to 1.5 hours.  After that it is $150.00 per hour.
  • Setting up an extra pair of shoes is $150 per hour.
  • Cutting seat masts, ATB handlebars and other necessary “surgeries” with the appropriate equipment is $100 per hour.
  • Replacing parts such as tires, chain, cassette or other components necessary to conduct the session is $100 per hour charged in 15 minute increments

The “put your money where your mouth is” Guarantee

We have such confidence in our bike fitter that Castle Hill Cycles will refund your full fitting fee if after 3 months post-fitting you don’t see positive results, given that you followed Jerry’s instructions and allowed him attempts to rectify and/or resolve your position issues.  This is where the good fitters and great fitters diverge.  A more stable and effective position should be readily apparent to Jerry as a professional based on his knowledge, experience and the intense fitting training he went through with Steve Hogg in Sydney, Australia.  The new position may feel vague or powerless initially but things should come around.  You have the final say in whether or not I have performed my job as promised, but there is a degree of responsibility on your end.  You must follow the exercise/stretching programs in detail, pay attention to your riding intensity and keep in touch with us.  Ride easy for 3-6 weeks, leave the wrenches in the tool box and trust that things will improve.  However, call/email us immediately if you experience any severe discomfort or pains that worsen over time.  Some clients adjust to changes quickly and others can take more time.  Jerry will be happy to work with you over the phone and via internet video for a period of 90 days post fitting to help with your new positional variables, free of charge.
