Argon 18 Nitrogen Ultegra Di2

At TCR Bike Shop our philosophy is “Fit before you Buy”

We may not have the most bikes on the floor because the majority of the bikes we sell are ordered to spec. Every cyclist is unique that is why we order the right bike for you.

Any time you purchase a bike from TCR we will run you through our bike fit process. This way there is no question of what size of frame you need. We will dial in your bar width and stem length and help you choose the perfect saddle. You can schedule your fit and we can help you find the perfect unique bike for you!
