| I admire the DIY ethos, but does that still qualify as a minimal mount? The CYO is a proven design that uses less metal. Since you’ve ditched a front bag/rack, is there another reason you’re avoiding mounting your light at the fork crown?

Sent from my Atari 400 <IMG_1524.jpeg> Since i had a spare light bracket set aside for a future project, i doubled up and now the setup has good lateral strength. Regarding other comments… putting a bracket directly on the hourglass boss would risk cracking the paint (assuming the light is bolted tight enough, with star washer, to eliminate rotational slip). At least that’s how it seems. As for the shadow cast… we’ll see how it looks IRL. My daughter and i totally messed up a SON coaxial adapter (soldering) today, so for now no actual in use report (and no ability to lengthen the run and relo to left fork blade). Might end up resorting to the plain spade connectors, which really aren’t so bad.

I might do something like this for the IQ XL in just installed on my Matthews dirt road road bike, since various constraints mean that my other headlamp mounting options are just below the bar as presently with bar-clamp mount (but lamp would be covered by rain cape in the event) or on the fender (would prefer to mount where removal of fender does not affect position), or on one of the fork legs.
My fork crown is not drilled, and I can’t drill it because I spec’d a very deep threaded fender boss inside the crown.

When I migrated from a randonneur frame to the Roadini, I decided to forgo a front (rando-style) rack and bag. This is what I came up with.
When I migrated from a randonneur frame to the Roadini, I decided to forgo a front (rando-style) rack and bag. I flirted with different light mounts on the market, but was underwhelmed. I had good experience previously with the Velo-Orange light bracket, but wasn’t sure if one would hold its position well on the Roadini’s hourglass fork bosses (and I didn’t want to crank too tightly on any bolts or star washers which might crack this pretty bike’s paint).
I found inspiration when I spotted thinwall aluminum tubes at the hardware store. This one was 12” long and cost $2.49. I cut it to length, flattened the ends, eyeballed thru holes, and mounted it using flat washers to keep the thin aluminum from being sheared by a torqued bolt or nut. Really pleased with its simplicity… and the tube hardly weighs a thing.
Importantly, this setup doesn’t have much lateral strength. It’ll be fine for regular riding. But if you were to drop the bike or lean it up against something the wrong way, the whole bracket assembly could be pushed/bent towards the spokes. If this aluminum tubing doesn’t last, I’ll re-do this with stronger stainless tubing which will be at least somewhat more laterally stiff.
And yeah… I haven’t landed the coaxial cable yet. I’m expecting a SON coaxial hub adapter to deliver soon, and will be using SON’s coaxial plugs to quick release. I might extend the coax long enough to have a left-side light mount, but for now it’s too short so will try it right-side and see how the light pattern (and cast shadow) play out.
