Light mount for side of fork
 
These used to be available commercially. Does anyone know of a source. The pictures in this album of my homemade solution. I want a peg mounted on the side of a fork onto which I can mount a light. I want this location because the handlebar and fork crown are occupied and unavailable.

That's not a bad idea. Looks like it works well.

GrainBrain 06-14-21 10:12 AM

Same here, subscribing for any ideas. My fancy new carbon gravel bike has a mount on the fork close to where yours is located.

I can't see in your photo if your fork has mid fork rack mounts. If it has them the Paul Gino mount is nice https://www.paulcomp.com/shop/compon...o-light-mount/

Chronometer NOB?

Maybe not the most elegant but they work well.

Problem Solvers has a solution: Universal Cycles -- Problem Solvers Braze-On Light Mount [LT0902]

Note some of the commercial solutions are a bit under-sized for some mounts.

noglider 06-14-21 02:15 PM

I think the Problem Solvers item is too expensive and needs a boss to screw into. My fork has none. The Nob on the Peter White site looks good, but he doesn't have an order page, and it's out of stock (and probably production) everywhere else, so maybe it's also out of Peter White's stock.

If Amazon does not have it, I do not know who would

I put these on my wish list a cpl years ago but never bought any of them, but I see now you don't want to screw into anything, sorry

that is genius!

this place has t-connectors +
but you already made something that seems perfect, why make something else if you can find a ready made product specifically for your purpose

Tubus LM1 Fork Adapter - mounting set for forks without eyelets #72100 ???

these things?

seems like the motorcycle world has tried to tackle the same challenge, but they have round forks

noglider 06-15-21 01:17 PM

That's all good stuff, [MENTION=134410]rumrunn6[/MENTION]. Thanks. I especially like the Tubus gadget because I've seen racks I'd like to put on though my forks don't have bosses. I might use that gadget for adding a rack. Given that all these ideas are expensiver than my homemade gadget, I'll keep making it. I've made it out of PVC pipe as well as copper pipe. Interestingly, I make them without using any rulers or other measuring tools. One of the hard and fun parts is mitering the pipe to fit the curvature of the fork. I just use a round file and keep checking the fit.

I have a pair but I am unwilling to torch off the attached Mooney. Peter brazed them on low as LowRider mounts. At that time he was unwilling to drill fork blades. Convincing a fork failure survivor wasn't hard! (We were clubmates when it broke. He almost certainly was at the annual club dinner 5 days later when it was announced I was in a coma.)

Great rack bosses! Only drawbacks - a little wider and slightly spread most racks and I have to drill or file the rack holes to fit the larger bolts.

Why not just mount the light sideways on the fork?

  1. The beam pattern might be designed to work with the light mounted in one way.
  2. You'd often lose the ability to redirect the beam up/down.

Yes, the light in my pictures is a German-law-compliant light with a very asymmetrical beam shape.

Tourist in MSN 06-16-21 05:39 AM

I generally do not suggest that you mount a light lower than you have used it. I have it lower on my errand bike against my generic recomendation, but I only ride that bike for short distances and then only on well lit streets. I use the light on my errand bike more as a to-be-seen light, not so much to-see-with light. And I get large shadows from small stuff on the road like leaves.

But that is an option if you want to try it. I used a threaded rod in the fender mount on the dropout. Or, you could use one of the skewer mounts cited above on a skewer, or some combination of that.

https://cimg7.ibsrv.net/gimg/bikefor...83fc09000c.jpg

I got the dynohub wheel for cheap from a bike charity, the vintage light was a bottle generator version (no switch) that was sitting on my shelf unused. Otherwise I would not be investing in a dynohub for an errand bike.

The light does get in the way on some bike racks that are designed for you to put a front wheel into the rack.

If the light is for commuting on roads that you travel on frequently, mounting it low like that might work well for you because you know the road well, then the large shadows are less of an issue.

This is the easiest wiring job I have ever done, the light was grounded to the mount, the Shimano hub is grounded to the fork, I only needed a single conductor wire, less than a foot long. Light is always on.

Being that light is on the fork the beam can be wherever you want it to be depending on how high or low you mount it on the fork.

I think you are overthinking this. Mount the light sideways on the fork. I'm positive it will work just fine.

No. The fork is angled. The light would always be pointed at an upward angle anywhere on the fork. You need to be able to rotate the light (not move it up or down).

And, for many cycling-specific lights, the beam has a cut-off at the top and floods horizontally below the cut-off. Orienting these lights by 90' would mean all that engineering wouldn't do much for you.

prj71 06-16-21 08:29 AM

Some of the lights I own can be rotated on their mounts. So not a big deal.

Again...a lot of overthinking going on here.

You keep missing things.

Many cycling-specific lights have beam patterns that don’t work well if not mounted horizontally. The OP has such a light.

noglider 06-16-21 09:19 AM

[MENTION=413198]prj71[/MENTION], perhaps you need to look at a shaped beam to see what it's like. If it's sideways or upside down, it's extremely ineffective. And I'm not asking how I can eliminate the mount I already have and works well. I'm asking if such a thing is commercially available because it works so well for what I need. So I think you're underthinking it, i.e. offering a solution to a problem different than the one I have. If I ask you what the weather is and you tell me what time it is, it doesn't matter how precise your time readout is.

noglider 06-16-21 09:21 AM

[MENTION=203914]Tourist in MSN[/MENTION], yes, on one bike, I have a special "nut" on my QR skewer that is big enough to mount a headlight. As you say, when it's that low, aiming it is tricky. I manage to get it to work, but it's less than ideal. The ideal height for a bike headlight on a bike with 700c wheels is somewhere between the fork crown and the handlebar.

adamrice 06-16-21 09:27 AM

Peter White Cycles sells a nob, which is basically a commercial version of noglider's homemade mount.

Minoura has a bunch of interesting mounts that might provide a different sort of solution, although nothing like this.
