I might be wrong, but I think only the 650B rim brake version is discontinued.

ok, that's right, I saw it on the 650b email list.

I don't even know what kind of rims I am using. My LBS manager picked them. They're heavy and they haven't broken yet. If they do, I'll build my wheel lighter.

Same as your rear wheel for cosmetics.

No. Its aerodynamics are horrible. It bends easier than deeper rims on road obstacles, which is a natural consequence of beam stiffness being proportional to the cube of depth - all else equal a 25mm extrusion would have 250% the stiffness of a 18.4mm deep Open pro.

I wouldn't do anything which requires proprietary parts, or an oddball rim less likely to be still available when you bend/wear it out and want to replace it without changing spokes and relacing your wheel.

Of those three I'd use the Archetype.

I built my current wheelset using Velocity Fusion HALO retro-reflective powder coated rims (originally a PowerTap front and rear, although I added another front built around a SON28 when I was riding too many hours after dark to rely on battery lights)

They've been around forever, so being able to get another for rim replacement without changing spokes is likely
25mm deep so they're durable without barn door aerodynamics
Not unnecessarily heavy
They're brightly illuminated by vehicle headlights

if it matters, he already decided

Thanks, Drew.

I like the idea of the reflective surface of the rim.

I decided on the Archetype.

My 2 cents - H + son TB14 for vintage strong rim. I've laced 3 or 4 now and they seem pretty good. Not at all aero though - Vintage looking.

Yep, I got it built, whole wired lighting rig was set up, and rode it for the first time yesterday:

H son archetype, polished Silver
DT comp spokes
Son 28 with 32 hole (only hole configuration Peter White had in polished silver Son28)
silver brass nipples
panaracer paselas 32mm

Sinewave Beacon light

Secula wired rear light

Soma San Lucas 2 front mini rack

Wald Basket zip tied to front rack (14.5"x 10"x9")

on Soma ES bike with 46/30 rings and 11-32 cassette

... It's comfy and more practical, but substantially heavier than my 2015 Cannondale Supersix Evo Hi Mod Dura Ace with Dinotte battery Front and Rear lights, Dura Ace wheels, that I've been doing 200 and 300km brevets on. I'll appreciate the comfort and functionality (basket,rack,dynamolights,gearing) when I hopefully do a 400km and 600km in a few months, but for the time being it rides like a cadillac when I've been used to a corvette.

I can't wait for the pictures, hint-hint.
