Dream Bike #2: 2011 Ridley Noah | Light. Fast. Aero.

The latest generation Ridley Noah shares the same
proven aero features as the first-generation version — including an
aero downtube, an aero seat tube that extends into an integrated seat
mast, plus a rear wheel cut-out. What sets it apart from its
predecessor is its use of Ridley’s R-Flow technology. As we all know
by now, drag increases exponentially with airspeed, which means small
changes to reduce your drag will have a disproportionately positive
impact as your speed increases.

R-Flow technology focuses on one specific issue of bicycle
aerodynamics: According to Ridley, your wheels produce 8x more drag
where they pass through your fork and seat stays due to the turbulence
of the colliding air masses there. The Noah is built to minimize this
drag thanks to its use of long, slotted airfoils built into both the
fork legs and the seat stays. These airfoils direct oncoming air away
from the turbulent areas near the wheels.

The story of the Noah goes beyond R-Flow. Ridley used oil mapping in
the wind tunnel to isolate spots of turbulent airflow. And where
structural limitations kept them from re-sculpting the frame, they
apply a textured surface treatment for boundary layer control. Ridley
calls it “R-Surface paint”, and our affectionate shorthand here is
“aero paint”. These thin stripes of texture are amazing: They
purposely trigger a known amount of turbulence that re-energizes lost
boundary layers, ultimately re-establishing laminar flow and
minimizing drag. In other words, they carefully create an airflow mess
in order to make an unprecedented cleanliness. Airflow control is why
you see vortex generators on jets, and why you see dimples on golf
balls. And it’s exactly what Ridley does with their R-Surface paint.

This bike descends like a demon… Super fast and extremely stabile.
