Radial, heads in or out?
I've got the American Classic Micro, the GEL280 rim and the spokes for a dedicated, radially laced, hillclimb wheel.
Heads in or out? Aesthetics aside, which for a more functional wheel?

Heads out puts less stress on the flanges. Heads in makes it a little more laterally stiff. If the hub is approved for radial use then I would say heads in.

The hub has thick flanges.

Heads out is also a little more aero, but all of those factors (stiffness, flange support, and aerodynamics) have minor effects. I prefer heads out for aesthetics and aerodynamics and haven't had any problems, but it's really personal for most people.

FWIW, I built one radial wheel (28s) alternating heads in/heads out. To tell you the truth I can't think of a reason to do it again, but there was nothing wrong with it.

The wheel probably wont go much over 7 mph. It really is a dedicated hill climb wheel for just one hill that they won''t let us ride down.
I'm registered for both Mt Washington hill climbs this year.

In that case go for the more laterally stiff for sure. If you're heavy or put out a lot of power you might actually even consider crossing it 2x. I've seen front wheels that rub the brakes when people climb on them.

The only thing I can add, regarding the OP's hubs having "thick flanges" is that heads in will put more stress on the bend of the spoke, although that's not really a huge deal on a front wheel. But a thicker flange will exacerbate the bend.

Hey thanks for all the input. I built it heads in.
Complete without a skewer in weighs 500 grams even. I'm going to run Vittoria Crono EVO-CS tires. The rear wheel will be a GEL280 laced to a Dura Ace 9 speed hub, 2 cross
