THE GURU FIT SYSTEM enables cyclists of all ages and experience levels to find the perfect bike and riding position to match their personal preferences.

THE RETUL FIT SYSTEM involves 3D motion-capture technology to reveal the precise angles through which all the joints and levers in you body are working dynamically, while you are riding your bike.

We have married the two leading fitting systems together. The GURU fitting system allows your body to be adjusted to the specific specs that are most comfortable for you. The RETUL fitting system then using 3D motion-capture technology reveals the precise angles through which all the joints and levers all work at maximum efficiency and comfort.

A supportive rider, who might spend twelve hours in the saddle, could be adjusted for comfort, while a flat-out time trialist could be set for maximum power.

Why FIT matters

Retul Fit

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 to finding the exact size that fits your unique needs and build. We promise to fit the bike to your body, not the other way around.

During the bike fit, we optimize your position for power, cadence, position 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. The more comfortable you are, the more you will want to ride your bike. And the more ride, the more efficient you’ll become. It’s not rocket science.

And when you purchase a bike from 40K Cycles, 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’s your body. Your budget. Your bike.

Our Mission

40K Cycles is fully invested in being a fit-first shop. That means we recommend getting a bike fit before you start shopping for bikes. 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. And we provide a bike purchase process that guarantees the bike you get fits precisely like it should.

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 riders themselves. Consequently, lots of athletes are riding bikes that simply don't fit.  But there is a better way.
