Lightweight, super strong, cost effective aluminum
tubing.
A4 aluminum is based on 6066 alloy, with high strength
and low weight without added expense.
Shared Pivot
Shared Pivot Technology uses a single point of
attachment for the main pivot and shock.
The SPT offers a mechanically simple and light-weight
suspension system. (Patent : US8033558)
Triple Butted Tube
Triple butted tubes are the hallmark of a high end
aluminum frame construction, and allow for maximum
stiffness at a minimum weight. A triple butted tube has
three different thicknesses along the tube length,
allowing you to focus material where you need it and
remove it where you don't.
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.
E-Type Front Derailleur
For suspension mountain bike frames, E-Type front
derailleurs provide more design clearance.
Plate mounted under the drive side bottom bracket cup,
with a screw threaded into a boss on the seat tube.
Post Mount DIsc Brake
Direct mounting your rear brake provides additional
torsional stiffness and eliminates adaptors, bolts and
excess weight.

Along with BB86, this Shimano BB92 Bottom Bracket is
part of the new press fit standard. Typical mountain bike
has a 68 or 73mm bottom bracket shell width, a BB92
equipped bike has a shell that measures 91.5mm wide
and has a 41mm inside diameter.
