Why FIT Matters
Like a t-shirt, bikes come in sizes such as Small, Medium and Large. Or, like a suit, you can find more specific measurements like 52cm, 54cm, 56cm and more. But we don’t believe in choosing a bike based on one letter or number. That’s why we take a more personal approach and promise to fit the bike to your body, not the other way around.
During the bike fit, we optimize your position for power, cadence, and most of all - comfort. Because whether you’re a recreational cyclist, mountain biker or triathlete, making you comfortable on your bike is our number one priority. We know that the more comfortable you are, the more you will enjoy riding your bike.
When you purchase a bike from Swim Bike Run, you can be confident that every detail was chosen according to your specific needs. It’s as tailor made as a new bike can get. After all, it is Your body. Your budget. Your bike.

Our Mission
SBR is fully invested in being a fit first shop. That means we recommend getting a bike fit in conjunction with your bike purchase - because the only right bike for you is the one that fits. It doesn’t matter if your budget is $500 or $5,000, any amount is too much to pay to gamble and get the wrong bike.
Bike "sizing" is at best inconsistent, and at worst, misleading. Bikes were once sized by measuring the distance from the center of the bottom bracket to the center of the intersection of the seat and top tube. If bike frames were all built the same, that would be fine. But they aren't.
Other bike shops may assume that all cyclists roughly 6 feet tall will ride a 56cm or 58cm, not taking into consideration the difference between brands, frame styles and the riders themselves. Consequently, lots of athletes are riding bikes that simply don't fit. But there is a better way.

Dynamic 5 Fit

This is our Olympic Athlete level fit.
Dynamic 5 Bike Fit:
This Bike Fit takes about 2.5 hours
Our expert fitters designed this Bike Fit specifically to be the most precise and athlete-specific fit option available in the midwest. Instead of limiting the bike fit to 3 effective seat angle positions, the Dynamic 5 Fit process follows a rider through five complete bike fit positions. The end result is a fit position that is tailored, to the millimeter, to a rider's strengths.
