The ultimate in strength and light weight, high modulus carbon is the basis for the new breed of ultralight weight frames.

APRO's removable mandrel produces a smooth and uniform surface within the carbon frame, allowing for less material for the same strength. The resulting bicycle frame provides superior strength and stiffness while being extremely lightweight. (Patent : M412121)

APRO design aerodynamic frame from months of wind tunnel reseach and fluid dynamic modeling.

Internally routed cables provides a clean, sleek appearance while tucking cables away from dirt and debris.

Tapered 1.5" lower to 1-1/8" upper; 1-1/4" to 1-1/8" is also available. Tapered head tube designs are stiffer and stronger than conventional straight head tubes, with the added benefit of offering a greater surface area for welding. Minimal flex at the front of the frame provides increased steering precision and accuracy.

E-Thru axles offer higher stiffness / rigidity than traditional QR system.

Flat Mount is a road-specific disc brake mounting system developed by Shimano. The clean and simple design accommodates the more compact road specific disc break calipers.

BB86 is among the new bottom bracket standards. It offers frame designers more clearance and provides increased stiffness. BB86 equipped bikes have an 86.5mm wide shell, with an 41mm inside diameter, and utilize a "standard" crank with external BB bearings.

Shimano Di2 available. The frame can be used for Shimano Di2 system.
