Darimo Carbon Carbon stem IX4

Darimo Carbon Stem IX4

It's not round, it's not square...

Square shapes are good for vertical stiffness

Round shapes are good for torsional stiffness

Our research has shown that the perfect design has to implement both shapes. Too little squared structures and the vertical stiffness and strength decrease, at the same time, a totally square design would loose torsion stiffness.
The IX4 stem is the best of both worlds, not round and not square, balanced to profit most of both shapes.
