Precision Bike Fitting

Why fit matters.

It's true that we've fit some of the top cyclists in the country. But you don't have to be a professional to enjoy the benefits of a precision bike fitting at Whole Athlete. The right fit can increase your power, leverage your strengths as a cyclist, help you descend and corner with confidence, and accommodate any injuries or limitations you may have. Even if you're new to cycling, you'll experience a new level of riding enjoyment with a bike position that's biomechanically optimal and uniquely yours.

Shopping for a new bike? Come see us first.

We help hundreds of athletes dial in the position of their current bikes. But maybe it's time for something new. We can model any new bike option for you and make recommendations based on your position, budget and preferences, including brand, frame material or favorite bike shop.

First we'll fine-tune your current bike, or use our fully adjustable size-cycle to determine the exact position that's right for you. Then we'll provide Computer Aided Design (CAD) models of new bike options, including frame size, components, seatpost, stem, handlebars, and gearing recommendations.

Our goal is simple: to help you choose the right bike with the right fit.

Custom geometry made to order.

Sometimes the right bike is a custom bike. Whether you purchase a bike from us or elsewhere, we provide fully fit-driven BikeCAD design services for the bike of your choice, ready to build. For those who dream of riding custom titanium, carbon, Ti-carbon mix, or stainless steel, we are very pleased to offer five custom bike options at the Whole Athlete Performance Center: Eriksen Cycles, Falconer Cycles, Firefly Bicycles, Land Shark Bicycles, and Seven Cycles.

Our philosophy.

Computer formulas and video capture tools are no substitute for knowledge and real-world experience. At Whole Athlete, we let experience both ours and yours drive every detail of our fitting recommendations. For example, while one goal in cycling biomechanics is to balance the body and work in a more even, bilateral fashion, each foot orientation may need to be adjusted in a different way to achieve that goal.

In addition saddles vary considerably in their adjustability and there are hundreds of options out there. Finding the right one is not only accomplished with precise measurements, but out in the real-world where you ride. Fortunately we stock a wide variety of test saddles so you can be sure your choice is the right one. Handlebars and lever orientation can mean the difference between descending with confidence and creeping around the turns. We are as well-versed in handlebar fitting and aerodynamics as we are in bike handling and riding styles.

For more information about our holistic approach to optimal fitting, check out our articles on bike fitting, fitting feet , saddle choices, and handlebar selection.

What to Bring to a Bike Fitting.

Bring your bicycle and equipment (shoes, clothing) ready to ride. If you are doing a custom fitting or do not currently have a bicycle, wear clothing appropriate to be measured on a bicycle, and if possible bring your cycling shoes and the clipless pedal system that you plan to use. If you do not yet have clipless pedals, we can help.

  Bike Fitting from Whole Athlete

You and your bike are an integrated system -
a holistic union of human and machine.

Don't just take our word for it...

"I was introduced to Dario and Whole Athlete when I moved to California to join ProMan Women's Professional Cycling team. I had heard rave reviews about his bike fitting and their holistic approach to coaching. Having been a cyclist for three years, I suffered from various degrees of knee pain, which I thought to merely be just part of the game. Dario showed me that I was wrong, utilizing minor (but crucial) adjustments to damaging attenuate movement and increased my efficiency. Once I made the trip to The Whole Athlete studio to get my road bike fit properly, I immediately saw results; I felt more comfortable and my upper body was more relaxed. Just as importantly, my knee pain has completely disappeared..."

"I believe Dario has given me the gift of cycling back.

The very next day after my fit, I was able to ride 40 miles without knee pain. You see, I had successful knee surgery back in July 2010 for a torn meniscus and runner's knee. However, I was still experiencing anterior knee pain while riding anywhere between 8 and 19 miles post surgery. The doctors didn't know what the pain was from, but Dario had an educated thought or two on the subject..."

"Over the winter, Dario and I decided to really fine-tune my Time Trial position. After several sessions of working with my inflexible body, we were able to get my position dialed in. For years I struggled with saddle height and bar drop, both of which were causing me great hip pain. We developed a position that is powerful and fast, and most of all pain-free..."

"Hi Dario - I have been meaning to write to you for quite awhile but keep forgetting. I just wanted WHOLE ATHLETE" | Precision Bike Fitting for Road, Mountain, Time Trial, Triathlon, Cyclocross & Track to let you know how much I love my bike now! It feels like a completely different bike...and, the best part is that I have no more knee pain and my toes do not get as numb as they used to. Also, since you changed out the stem and moved my handlebars, I love riding in my drops and it has helped me improve my descents a great deal. I rarely used them before...they just didn't feel right. But, now that is where I spend most of my ride. I feel much moreconfident going down Diablo now!..."

"Thank you for the amazing experience yesterday during my bike fitting -- for the abundance of information, your expertise, and all the time you spent with us.

I took my bike out for a ride this morning and was really amazed how good I felt. My upper body felt sooo relaxed. I think I have been fighting with my positioning on my bike (straining to conform to the wrong position). I had relaxed shoulders, chest felt more open and did not have to constantly try to settle my shoulders as they were already down. I am certain my neck and shoulder discomfort will go away because of this. Also, I didn't need to adjust my body position at all. I just sat in the right place and pedaled on without any readjusting - amazing..."

Bike Fitting from Whole Athlete

Whether you're a world-class professional or beginning cyclist, everyone deserves a good fit!

"When riding for a professional cycling team, bike sponsors change from year to year. Also, as a multi-discipline cyclist, I have more than one bike that I ride on a regular basis. It is so comforting to know that I can take my bikes, whether road, time-trial, mountain or track, to the Whole Athlete Performance Center and trust that I the best possible bike-fitting done..."

"After months of knee problems on the bike I sought out experts in the field of bike fitting and sports medicine. I was fitted and treated by three different, well-known professionals throughout the country. While I respect their experience and knowledge, none were really able to help me with my knee problems, and I never felt quite right on my bike. Finally, I was referred to Dario Fredrick of Whole Athlete. His no-nonsense, practical approach to bike fitting made him my last stop. Dario was able to fix my position and help my knees! I have been pain-free and loving the bike since. Thank you!!"

-- Ken, road & MTB cyclist

"Let me just say....Holy Crap! It feels like I'm riding a whole new bike. The hamstrings at the tops of my knees don't burn anymore and I actually feel all the leg muscles engaging. Funny how that works when fitted properly..."

-- Aaron, road racer

"I wanted to write to check in via my bike fit I did with you about one month ago. It's really making a difference. I feel comfortable and powerful thus far and the watts are coming back up after several months of little or no riding due to a hamstring issue. Anyways, I'm very happy and confident in your fits and I just want to say thank you again."
