ASSEMBLY
There is some assembly required upon receipt. Your bike will be completely assembled and tuned by Borealis, then partially disassembled for shipment. The remaining assembly will require installation of the rear derailleur, chain, fork, seat post, wheels, and handlebars. A multi-tool will be included with your order that has all tools necessary to assemble the bike, with the exception of a torque wrench. If you are not familiar with this level of assembly, we recommend having your local bike shop complete the assembly. Below is a video showing the remaining assembly once you receive the bike. Tires will be set up with tubes. Tubeless rim tape and valves are included on the side.
Customer Reviews
Received my bike pretty quickly. Minor issue with FedEx splitting up the boxes, but nothing major. Love the bike, super fast. One item to note is that even the Size Small frame comes 175mm crank arms. Not a fan of the large crank arms, so may have to swap those out. Other than that I think the bike was a fantastic purchase.
Great experience ordering from Borealis. Order showed up early and was packed really well. Assembly was super easy. This bike is super light and of the best quality
