* All specifications listed are subject to change without notice. Please note that our specifications may be impacted by manufacturer component substitution changes caused by high global demand for bikes and resulting supply chain issues in the bike industry. We recommend confirming the specifications with your local Evo Cycles showroom if you have any questions.
Bike Weight: Many brands strive to list the lowest possible weight, but in reality weight can vary based on frame size, finish, hardware and accessories. The most accurate way to determine any bike's weight is to have your local showroom weigh it for you.
