The ultimate in strength and light weight, high modulus
carbon is the basis for the new breed of ultralight weight
frames.
NJW
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)
Aerodynamic Technology
APRO design aerodynamic frame from months of wind
tunnel reseach and fluid dynamic modeling.
Internal Cable Routing
Internally routed cables provides a clean, sleek
appearance while tucking cables away from dirt and
debris.
Tappered Head Tube
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 Dropout system12x142
E-Thru axles offer higher stiffness / rigidity than
traditional QR system.
Flat Mount DIsc Brake
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
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.
Di2
Shimano Di2 available.
The frame can be used for Shimano Di2 system.
