Light mounting problem

The front lighting of my bike used to be done with 2 lights on 2fish lockblocks on my handlebars, but it seems I created a little problem for myself.

!! Warning !! Long post ahead :crazy:

Recently, my saddlebag died, a 4lbs chainlock in a saddlebag intended for a lightweight rain jacket and a puncture repair kit might not have been such a good idea afterall. :shrug: I wanted something a little more spacious and stronger to replace it, so I went with a Ortlieb 'Ultimate 5 plus' handlebar bag. The bag itself is great, everything I was looking for in a bag, but when mounted it sits a little higher than the handlebars, making the use of handlebar mounted lights impossible. :banghead:
I've been looking at other mounting options, found a lot and discarded all but one (and that one works but is absolutely fugly) and I would like to keep it a bit good looking as it's a very nice bike...

Moving the lockblocks to another position on the handlebars doesn't work as I mounted curved bars due to shoulderpains. While there is plenty of space, the curve of the bar makes it impossible to use the lockblocks, the lights would point away from the road, making them useless.

I looked at other handlebar mounts, like the adjustale Fenix mount, but the mounting clamp is too long and wouldn't fit on the curved bars.

I looked at things like the minoura spacegrip and the likes, but they interfere with the opening of the bag (it opens towards the front of the bike), so that option is out.

I thought about mounting a 2nd stem, with a piece of cut off handlebar and mount the bag on that, below the handlebars, allowing me to keep the lighs in their original position. But I already have a extender mounted, which doesnt have enough space on it for a 2nd stem to be installed in a safe manner.

So much for the stem & handlebar related options.... On with the fork...

My bike has a carbon fork, the fork doesn't have mounting points for anything else than brakes. I dont want to clamp anything to the fork in a place that's not reinforced, so the option of using a clamp-on stud is out, there's a rubber band clamp-on stud variety too, but these are not suitable to mount lights with on-board batteries on.

I want to keep the disc mounts free for a possible future disc upgrade and I prefer central mounted lights as they give less of a shadow from the rim. The v-brake mounts are currently in use for my brakes so that only leaves the mounting point at the fork crown for the road bike style drop brakes. This is a good thing, as it allows for the desired central mounting position, I found a (Thorn brand) ready made mounting bracket, but there's also the top bit of the v-brake assembly thats very much in the way for this.

I even considered losing the battery lights alltogether and go with a dynamo setup. As there are plenty standard brackets available for dynamo powered lamps to mount to the fork crown. But due to the carbon fork & clamping issue, a bottle dynamo is out (and my AXA HR dynamo doesn't fit properly on the rear of my bike due to s-bend seatstays). So that would mean getting a hub dynamo, which would mean an entire new or rebuild front wheel and as I want to keep the disc brake option open, I'd be pretty much stuck with the Shimano Alfine or SON hub dynamo, both quite a bit out of my price range at the moment. :broke:

The one option I have left is to make a mounting bracket myself, which isn't too hard (a bent strip of aluminium flat bar, some nuts & bolts and a piece of tubing to strap the 2 lockblocks to would do just fine) but as I have very little tooling when it comes to working with metal, it would become one ugly *** hackjob... :sigh:


So, does anyone have a suggestion on where to buy or how to make a decent looking sort of T-bar construction to host 2 lockblocks that mounts to the fork crown brake mounting point and doesn't interfere with the v-brakes?

Some pics that hopefully are helpful

My "usual" pic,
You might just have seen it in another actual post.

fights my main critic of the Lockblocks: not movable sideways

if You dont trust it, use an additional rubber ring, put over front part of light, around bars and over rear part
(but for usual, the problem is getting the clamps from the bars. Tight fit)
😉
 
What about a "quick fist" adapted for this purpose? The pic shown is probably too big but they make smaller ones. Google "mini quick fist."


You may need two of these back to back like yellow's pic.

Yellow- where did you find those clips? What is their original task? I have been looking for something like that for another application.

Thanx wes wall. i googled 'em and those look awesome for lotsa stuff:twothumbs. Yellow mentioned we should be able to find the other clips at most hardware stores. this what he said:

Did you look at the Paul light mount?

Yes I did, and there is nothing to mount that mount to...



What I'm looking for is something that bolts to the fork crown, as that's the only properly reinforced area of my carbon fork that's suitable for mounting stuff on and there is plenty of space between fork crown and the bottom of the handlebar bag for some lights.
Clamping anything to the legs of the fork is a no go, as the manufacturer recommends heavily against it... and clamping to the handlebars would give a less then optimal beam as the light would shine on the bag casting a shadow on the road in front of me.

Keep the ideas coming!
 
Here EFMax mentions mounting his light with a Hope hed docter in the open lower end of the steerer tube. Perhaps this is part of the solution to your problem?


Or you may try mounting your light to your bag, as I did with my tail light:

I saw that pic too when searching the forums for a suitable mounting option, while I think it's a pretty cool solution, it's not what I'm looking for. I have a place to mount the light, I just need something to mount there.

But you did give me an idea.... I might be able to use the 'top caps' of a set of hope grip doctors to fix a piece of handlebar tubing to a dynamo light bracket. I'm thinking cut an opening in the middle of a peice of handlebar, glue some locknuts to the bracket, insert the nutted end through the cut out opening in the tube, put some bolts through the 'top caps' of the grip doctors, and screw them into the locknuts on the bracket. And the bracket is an easy fit on my fork crown...
This would give me the T-bar construction to put my lockblocks on....

Now I need to find out if grip doctors are easy to take apart without damaging the caps.

Thanks for the inspiration!!
 
Why wont the minora work?
Point it up or even back somewhat.

The top of the bag is already above the handlebars. the minoura simply isnt tall enough. I want the edge of the beampattern to be about 3 feet in front of my front wheel, to achieve this with the lights mounted above the bag, it would either have to point forward, but this would interfere with the accessibility of the bag, or the lights would have to be mounted very high up, even the biggest minoura is too short and another issue with this is that the lights would be in a very awkward position and a potential hazard in case of an accident.

All these problems can be easily avoided by placing the lights underneath the bag, where there's plenty space, but only 1 available mounting point.


But with the Hope head doctor idea I had a little inspiration... I made a little sketch of what I have in mind... I didn't have any napkins or coasters available, so I had to use a post it note...

I could mount any standard handlebar light on that...

Ah, I Missed that you have the central attachment hole for a mud guard. Sort of like my own bike:

You make your bracket go down first, because it would interfere with the rest of the fork if you go up directly. I have that same problem, but solved it by placing some stainless steel washers between the aluminum strip and the fork crown. This simplified construction a lot.

on my fork, that's an attachment hole for a brake 🙂 I plan to have the bracket go forward a few inches so it will clear the v-brakes and then go up. The more forward position is needed to make sure the batterytubes of the flashlights on the lockblocks don't hit the frame when cornering (as I'm planning to keep the whole construction as narrow as possible to save weight and improve stability).
 
That makes sense 🙂 It is also a good idea to use a "U" profile as you have drawn instead of the flat sheet I used as this will make the bracket stiffer.
 
I'm planning on using a standard bracket for a dynamo lamp as the base. Neater, stronger and probably lighter solution, saves work and the bracket is probably cheaper than the length off alu u-profile needed to make it myself. And available from pretty much any bikeshop in NL (and there are a lot of them here, just too bad that most of them are closed on mondays)....

The type of bracket I want to use as a base:

cost: 0.80 euro (about $1)

how about a simple brake-booster as primary holder?
There is no more "rugged" part at the fork to mount anything than the brake sockets
 
I thought about that, but I'd still need to add something to it to accept standard handlebar light mounts. So there wouldn't be much difference when it comes to the work involved, so I decided to go with the dynamo lamp style mounting bracket, as they are a lot cheaper than brakeboosters. The bracket is 80 eurocents, while a decent brakebooster would cost me about 10 euro...
