M6 is the industry's highest quality aluminum tubing,
with high tensile and yield strength, as well as superb
elongation properties.
M6 aluminum alloy is based on 6069 aluminum with the
addition of trace elements to provide a higher stiffness
and strength than 6069 aluminum. Thinner M6 tubes
can be used to provide for an overall lighter weight
frame without the loss of traditional aluminum ride
character. (Patent : I223669)
Optimized Instant Center
The OIC system is engineered to have linear shock rate,
allowing the shock to be tuned for the widest variety of
conditions.
OIC avoids all current patents by using an anti-squat
curve and IC migration that is different from that covered
in other patents. (Patent :US7909347)
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.
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.
Direct Mount Front Derailleur
Direct mount front derailleurs provide for increase front
derailleur stiffness and perfect alignment Direct mount
derailleurs eliminate the clamping system, toeliminate
weight, and work with press fit bottom brackets.
Post Mount DIsc Brake
Direct mounting your rear brake provides additional
torsional stiffness and eliminates adaptors, bolts and
excess weight.
PF30
The PF30 is a variant of the BB30 design.
The PF 30 design uses BB30 size bearings preinstalled
in bearing cups.
The bearing and cup are pressed into the PF30 bottom
bracket shell. PF30 uses the same diameter spindle as a
BB30, the cup material increases the bottom bracket
shell to 46mm diameter.
