Darimo IX2AL Stem

 

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 we want 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.

Our 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.

It’s body shape and a 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 under 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.

Clamping diameter: 31.8mm (Other diameters under order)

Angles: -6º, -12º, -17º y -25º (More angles under order)

Lengths: 40-50-60-70-80-90-100-110-120-130mm (Other lengths under order, as your needs)

Steering diameters: 1-1/8″ (Other diameters under order as 25.4 o 1-1/4″)

Clamping width: 48mm

Stack height: 38mm

Customized Options: Your name engraved over the stem? Different angle, length, colour? Just ask us!

Which angle and length would I need?

We can give you a dimensions chart, but what about a nonstandard angle or length? Then we give you ALL the information in the next Excel sheet. You will calculate the Reach and Drop for the stems, even including your frame angle to know the exact position of your handlebar.

Darimo IX2AL dimensions

What about using it for Road or Gravel handlebars?

Yes, it’s possible with our Darimo Ellipse handlebar.

Why that shape?

Why we produce 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) we have manufactured the power with the perfect cross section.

The external dimensions allow an adequate alignment of the fibre with the handlebar and steering tube. We have 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, we have achieved the combination that provides the stiffer and lightness possible. The following graph shows the results of the analyses performed. We do not choose the shape, engineering chooses it.
