Rear Drop Pivot is a Horst link style suspension system.
The four bar link design allows for fine tuning on both
wheel travel path and shock rate.
Internal Cable Routing
Internally routed cables provides a clean, sleek
appearance while tucking cables away from dirt and
debris.
Double Butted Tube
Double-butted tubes are thinner in the middle, and
thicker at the ends. Double butting reduces the amount
of overall tube material needed without a loss in
strength.
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 system12x148
E-Thru axles offer higher stiffness / rigidity than
traditional QR system.
Hydro Forming
Hydro forming is a cost-effective way of shaping ductile
metals such as aluminum into lightweight, structurally
stiff and strong pieces. Hydro forming is a basis for
creating complex shapes, and produce stronger, lighter,
and more rigid unibody structures for frames.
Post Mount DIsc Brake
Direct mounting your rear brake provides additional
torsional stiffness and eliminates adaptors, bolts and
excess weight.
