Get Fitted

Top reasons to get a professional bike fit:

Need for Speed

If getting that elusive PR, KOM or Podium spot is your highest priority our perfect fit system will improve your power and efficiency by optimizing the rider-bike connection.

Aches & Pains

Soreness in your neck, shoulders, back, arms, hands, legs, saddle numbness/irritation, toe numbness, and cramping are typically caused by a poor rider-bike connection - we have the knowledge and tools to fix this.


If you're just getting into competition you'll want to do it right! Aerodynamics, efficiency and comfort are crucial to this challenging sport - investing in a bike fit is key to your success.

New Bike

Awesome, you just got a new Road / TRI / Gravel / Mountain / Peloton / Commuter bike! Get started in the best position so you can focus on your recreation or competition.

Our Bike Fit Philosophy


Being comfortable will allow you to focus on more important matters like the adventure, increase your enjoyment with your fellow cyclists, beating your friends back to the trailhead so you can get that cold one, developing your aerobic/anaerobic capacity, pushing your VO2 Max, making up some lost time from the swim (my tri folks), and maximizing your performance on your road bike, mountain bike, or gravel bike!

Holistic Hands-On Approach

We use the Specialized Body Geometry Fit (Certified in 2013) method which consistently nets amazing results through assessment, adjustment, evaluation, and practice to optimize your bike riding position, saddle and shifter angle/height, shoe to cleats alignment(including Speedplay pedals), so we can keep you injury free and minimize any issues later down the road.

Guaranteed 100%

Once you receive our professional bike fitting, we follow up with you to make sure that you are still feeling a great bike-rider connection. We'll schedule any followups if needed to get you feeling 100% on the bike and make any changes based on your feedback.

Our happy clients love how comfy we can make them feel on the bike and consistently leave us 5 star reviews!

It took me a while to finally take my bike out given crummy weather when I tried to ride and some travel, but just did 45 miles yesterday (paradise loop and some hills in Corte Madera) and WOW, what a difference. I had no back pain and arms felt great. I felt my power was a lot better (using a lot more glutes now).


Kate and I wanted to follow up with you about our time on the bikes since being fitted. I have no complaints and everything feels great. My knee pain has subsided and I feel considerably more comfortable on the bike and as thought I have a lot more power when riding. Thank you again for a great job!


Thanks again for the amazing bike fit! Easily one of the best and rewarding investments I've made on the bike. I've been riding a lot trying to find anything that feels slightly off since our fit. Nothing has stood out to me, My leg fatigue feels a lot more balanced, back pain is basically gone from what I can tell, it's amazing I can feel my toes more than 30 minutes into a ride!


Went for a quick spin today and felt great. Felt much more power from both legs working together. I could throw the bike around on flats / corners too, getting more speed. Saddle felt great also on a good climb, actually I had forgotten it was even adjusted, it was so un-noticeable that I wasn't slipping off the back! Looking forward to a few more rides on some of my regular routes and having some measurable results!


I've been wanting to reach out to you too because the new setup is AMAZING!!!! Seriously, it is SO. GOOD. I wanted to give it enough rides to be sure, but it is most definitely true. I've been on several smaller rides and then went on a 40 miler on Tuesday, and it just all feels right on. I love the extra reach and slightly up position of the handlebars, the cleat replacement is spot on, and I am falling in love with the seat.


Just a quick update - overall the bike fit has been amazing! I did a 2 short 30-min recovery rides and then the Marin Century last Saturday. Took about 20-30 miles to settle in. Initially, there was some tightness in my interior thighs and a bit more pressure on the sit bones than I was used to. But once I settled in, everything started to flow, I relaxed and felt very much at ease and comfortable. Certainly feels like I'm juicing out more watts now! Finished the ride without any weird pains or soreness!

While the process is complex, the goal is not: Comfort. Over the years I've found that comfort is key allowing my clients to focus on more important matters like the adventure, enjoying the moments with your fellow cyclists, beating your friends back to the trailhead so you can get that 'cold one', developing your aerobic/anaerobic capacity, pushing your VO2 Max, making up some lost time from the swim (my tri folks). Regardless of your cycling path, I'm here to help. While I do incorporate minimal technology I find the holistic hands-on approach from Specialized Body Geometry Fit (Certified in 2013) method consistently nets amazing results for my customers through assessment, adjustment, evaluation and practice. If you're committed and care about a better cycling experience, lets make it happen together! --Happy Miles, Brian
