High Performance Aerodynamic Road Racing Bike – 18.3lbs (8.3kg)

Full Shimano® Drivetrain
Proven performance and reliability from Shimano®’s latest 105 22-speed drivetrain.

Full Carbon Frame
A full carbon monocoque. Ultra stiff with aerodynamic profile tubing. Our M size frame comes in at 980g.

Aerodynamic Excellence
The Laguna ARB frame tubing has been designed to be as aerodynamically efficient as possible while conforming to UCI rules.

The cross sections of the ARB’s frame tubing is the same as a high-speed bullet. This design yields significantly lower drag compared to traditional aero frames.

Yet another benefit to this bullet design is a 10% stiffer structure over oval tubes. This means more energy can be transferred from the rider to the road.

Perfect Balance
Balance is the holy grail of any race machine. Our racing DNA is alive in the ARB’s frame design, capturing the perfect balance between aerodynamics and stiffness.

Traditional aerodynamic road bikes suffer from flexing under load due to compromised tube shapes. The ARB cuts through the wind while offering the stiffness desired by sprinters.

The ARB fork cleverly manages airflow around critical parts of the frame, thus allowing use of stiffer tubing shapes where necessary without compromising the overall drag resistance of the frame.
