Nestled in the Mississippi river valley in Southwest Wisconsin sits Blue Steel Bikes. BSB is a one-man frame builder specializing in steel and titanium bicycle frames. Paul Reardon has been in business and welding frames since 2010, starting off with lugged and fillet brazed steel road and mountain bike frames.

After enrolling in the United Bicycle Institutes titanium program back in 2016, titanium frames are now 90% of the business these days.
Their location sits at quite a bit of elevation in the driftless region of South/West Wisconsin. Paul says, “with Iowa and Minnesota right across the river, we have some of the best gravel around. As you can imagine we primarily build gravel, and road plus bikes due to our location”.

BSB does all of its frame design, machining, welding, and anodizing in-house. The shop is a small 2000 square foot space with everything they need to build your frame.
They don’t do any production frames, only custom frames built one at a time for each client.


The Order Process
Step One: Let’s Get the Ball Rolling
A simple email or phone call will get things started. A preliminary conversation about what you are looking for is the first step. I always encourage clients to schedule a time to come by the shop and discuss things in person. We are starting a journey together, so let’s get to know each other. We can discuss your dream bike, and go over our process.
Step Two: Make a Down Payment
We require 50℅ down to reserve your place in the queue. This allows us to order materials for your build. Balance s due upon delivery. Down payments are non-refundable.
Step Three: The Fitting
With every custom frame build, we included a professional fitting. We work with Dr. Deb Slota at Bike and Body in Milwaukee. Deb is a fantastic fitter, and can address the needs of your body, and generate precise fit numbers.
Step Four: Design
Step Five: Production
Step Six: Finish Work
Step Seven: Assembly
