Took time to develop the internal cable version of the original HyperStem and still keep that same high stiffnes and low weight.

Adding holes doesn't make a highly structural product lighter at all
On the contrary they required several reinforced areas in order to maintain the well proved stiffness and safety.

Grade5 titanium black PVD coated Torx bolts with special "rounded heads" are the standard equipment.

Well rounded edges on all clamps make it fully carbon-friendly.

Over one hour of continuous 3dimensional CNC milling and contoured shapes on a huge multiaxial Mazak Intergrex machine

Exceedes the EN safety standard requirements so much that we can recommend it for Enduro use.

Fatigue and strength tested, exceeds UNI 10518 safety standards.
