Specifications:  

Introducing the new Darimo IX2AL stem, the perfect stem for those who love aluminium stems, and of course really light with just 82 grams in 100 mm length.

The stem is sculped from a 7075 aluminium block with precision CNC machining process.

Each stem needs near to two hours of continuous CNC machining as Darimo wants the best surface finish even with its organic and round shape. That shape increases the stiffness/weight ratio.

The stem has an integrated faceplate with only 2 closing Ti bolts. This design gives an impressive shape, awesome aesthetics and increases the stiffness at the clamping zone with the handlebar.

This design is optimized for carbon fibre handlebars. The clamping zone is not divided in two small plates, both bolts are connected, then the surface pressure over the handlebar is reduced. 

Its body shape and the huge contact surface with the handlebar (24 square centimetres) makes it stiffer than heavier stems.

Finishes: Anodized in Black Bright, Black Matte, Natura. Other colours are possible (special order)

Weight limit: The Darimo stem is safe and exceeds the tests of ISO 4210-2, but it is not recommended for riders over 90 kg. Request the reinforced version if necessary.

Weight (+-3%):

Why that shape?

Why Darimo produces a stem with not round section? Why not square?
It is not an arbitrary decision, it’s an engineered design.
After many computational finite elements analysis (FEA) Darimo has manufactured the power with the perfect cross section.

The external dimensions allow an adequate alignment of the fibre with the handlebar and steering tube. Darimo has shown that a power with square-circular section (square with rounded edges), at equal weight, is torsional stiffer and the stress is reduced by 20% compared to a perfectly square or round section. Therefore, they have achieved the combination that provides the stiffer and lightness possible. They do not choose the shape for aesthetic purpose, engineering chooses it.
