Welcome to's North American Bike Fitter Database

543 fitters and counting. This collection of fitters is the most complete and comprehensive selection of bike fitters in North America.

F.I.S.T. equipped fitters

Fitters who have attended a F.I.S.T. tribike fit workshop *AND* who have what we consider to be a F.I.S.T.-compatible fitbike (Purely Custom, EXIT Cycling, Retul, Rob King, or Guru DFU) have a special icon to designate what we consider to be a particularly important confluence of skills and tools. You will see this icon prominently displayed on the regional, state, and top fitter lists, on your advanced search results, and also on the fitter's individual page. Look for this icon if you want someone who has both the equipment and the training to execute a textbook F.I.S.T. fit.

Searching the database

Our Advanced Search is very potent, and will help you drill down to that set of fitters conforming to a specific purpose you have in mind.

Browsing the database

You do not need to log in to do this. You'll find a list of fitters in your region by clicking the regional links on the left. Click the (+) sign and the region will expand to expose the individual states. Click on the state to show that list of fitters in it. If you want to see fitters in multiple states, but not those states we've aggregated into the regions you see at left, you may do this via our Advanced Search.

Showing solidarity with your fitter

When you see your local fitter listed here, you may click the "I WAS FIT HERE" button. Your User Name will be added to the fitters's list of clients, just like your User Name appends to those races you choose when you build your Slowtwitch Personal Race Calendar. Likewise, your Forum User Profile will show that this is your fitter of choice.

How to enter a fitter

You must be a registered user to add a fitter to the database. There is one common type of registration on Slowtwitch, and if you are registered to post on our Reader Forum you are one of 101,721 who have made a registration, and this means you're able to add fitters to our database.

If you're not registered, the login prompt is to the left of the page, near the top. The registration process is straightforward, easy, and free. It will require you to receive an email and click on a link to complete your registration. All this should take you only a minute or two. Then...

1. Click the ADD A FITTER button to begin adding to the database.

2. Once you SUBMIT your fitter, you'll also need to CONFIRM your submission via a link at the bottom of the page.

3. Once you successfully add your fitter, it will not immediately be visible to you. We must validate the addition on our end before anyone can see it. We do this so that spammers won't use the fitter registration as a way to spam our database.

How to edit published information about a fitter

Any registered user may edit information for a listing. We will review the full contents of each update before confirming any changes that are made. A list of all editors who have made changes is visible at the bottom of each listing. If an entry has been updated, but those changes have not yet been confirmed, this is evident via a note on the individual page for that particular entry. This is to prevent conflicting updates from occuring simultaneously. If you wish to update an entry with pending changes, please wait until we have had a chance to review those changes first. Someone may have already changed the information you were going to change yourself.

How to comment on a fitter

Any registered user may make a comment on a fitter listing. These comments are subject to validation by an administrator before being published.

Global fitter map

The map below shows the location of all registered Slowtwitch fitters around the globe. You can drag the map, zoom-in, zoom-out, and use any other of the standard Google Maps features. Anywhere you see a red icon, you can click to see the name of that fitter and a street address.
