The first things
that springs to
attention is the
spiral design on
the outer face.
It reminds me
some hypnosis
session !

This design inspired by the shape of golf’s ball but
adapted for the aluminuim machinery is more
aerodynamic than a smooth outer layer.

The « Direct Mount » is also helping to reduce the
drag. By the fact, the chainring is directly fixed
to the crankset (so not on the spider) which is
improving the airflow along the chainring.

Without a inner chainring, you don’t need some
components like the front deraillor and the
deraillor hanger. By consequence, the drag is even
more reduced than with these components by few
watts.

Even I’m not able to attest that the power transfer
is improved, I’m convinced that the direct mount
allows a better power transfer from the pedal to
the chain.

To install the chainring, it is quite simple. You just This video is explaining step by step how to do it :

onto the crank. It’s obviously crucial to respect the Switching to single chainring has also the
