Anemoi Mk2 Extension Fixed Risers

1 review
Angle: 10 Degrees

Designed specifically for our Anemoi Mk2 extensions these fixed-angled risers optimise the relationship between extension body and riser. Reducing drag in a sensitive area to increase aerodynamic efficiency.

They are compatible only with our Anemoi Mk2 extensions when used in conjunction with our conversion spacers, mount plates, brackets, riser stack spacers or Anemoi basebar. They can not be used to attach to any other setup.

Please note, this product is not compatible with the Anemoi Mk1 Extension System.

Product Description

The extension to riser relationship is incredibly sensitive to airflow. Our initial testing proved that this was a high-drag area. To improve aerodynamic efficiency we replaced the adjustable riser with a seamlessly integrated fixed angled riser.

Our testing has shown a CdA reduction of 0.003m^2. At 50kph with an air density of 1.225kg/m^3, this equates to a Watt saving of 4.9w.

We recommend fixed angled risers for athletes who have either locked in their riser angle or are looking to maximise their riser angle within UCI regulations.

Due to the fixed design the risers have a locked in 2 degrees of toe-in.

Manufactured from 6082-T6 aluminium and anodised black. Compatible with fully internal cable routing. Laser etched for angle and hand on the rear trailing edge.
