Raven Hang Gliding LLC (
www.hanggliding.com )
is pleased to announce that we have gone into production on the hubs for ATOS
carbon base bars. We now offer wheels/hubs to fit over 99.9% of all the hang
gliders on the planet.

We’ve made the first batch of production hubs, and we’re very pleased with the
fit and finish.

These hubs are more complex than the hubs for other carbon bars (such as our
hubs for the Wills Wing or Moyes carbon base tubes).

What makes the ATOS hubs more complex?

They are designed to go on/off the basetube while the glider is fully assembled,
with no tools. The hubs open like a clamshell and close around the basetube. The
wheel halves complete the assembly. No parts need remain on the basetube (except
for a few rubber bands or wraps of tape).

They are designed to sit on the basetube itself, just outboard from the skid
humps. They are not intended to fit on top of the skids.

The skid humps will limit any travel of the wheel inboard on the bar. Wide
rubber bands and/or tie wraps and/or tape will be used to limit any travel in
the outboard direction.

The basetube angles up at 10º just outboard of the skid hump. For this reason,
the airfoil-shaped center bore of the hub must also be angled at 10º to keep the
wheels vertical.

The basetube has two distinctly different curves in cross-section. The
top-surface curve is different from the bottom surface curve.

Between the asymmetry of the cross section and the 10º angle, the hubs have to
be made as dedicated right and left side pieces (part # HLAL and HLAR). We can’t
simply flip the hub and use it on the other side.

The HLAL and HLAR hubs are made to fit our W6LN, W6LD, and W8L Whoosh!Wheels.
You will be able to use these same wheels with interchangeable hubs to fit the
Moyes or Wills carbon bar (or similar), sold separately. If you already have a
set of our W6LN/W6LD/W8L wheels, we can sell you a set of hubs to fit the ATOS
bar. As always, individual components are available as needed.

NOTE: The hubs for the ATOS bar will not fit our popular W6S or W8S wheels,
which have a smaller center bore and are intended to be used on aluminum base
tubes. Our products for carbon bars are not interchangeable with our products
for aluminum bars.

Orders are welcome ( <info>
), and will be filled on a first-come, first-served basis. We expect our first
batch of HLAR and HLAL hubs for the ATOS basetube will run out fast.

$230.00/set including 6.25” wheels, add $10/set if you prefer 8.00” wheels.
