Dynamo Lights

I haven't got an entry yet.

Though you'd be ushered in VIP style!

There could be some way of mounting it to the top of the bridge inbetween the stays?

HVIPPY: "Not that gobby fuckwit again..."

There's a brake mount hole so a bracket there might work. I don't have the frame so I can't tell. Keeping it on the seattube means the cable doesn't have to extend to the stays and brake bridge. Shorter cable run, less likely to be caught on something.

That's very neat!

Available to the hoi-polloi @M_V ?

thats nice, is that a bike? can you ride it?

Up the seat tube to where the stays join it, then back down the stay (rather than directly across from the seat tube).

Shorter cable run than running it to the saddle and less likely to get snagged by a strap through the saddle.

Thanks.

Could be but that design is somewhat specific to the width of the stays (so the light is centralised) and the angles (so it sits straight).

It’d probably be easy enough for someone to tweak it into the right shape but I was thinking that one that bolted to the bridge might be a bit more universal.

I also want to change the way the light attaches as I think I can improve that aspect.

I think I’ll try make myself a new one (I currently run one like @gillies) and if I can make it work how I want I’ll offer them to others.

Is there a standard for siting rack mounts ( @coldharbour )? I'd think the distance between them is a fairly small range, which would make designing a more universal mount easier.

You've got a flat plate mounted on a round bar: strikes me you have most of the ingredients for a means of adjusting the beam vertically.

Mounting it on the bridge is an obvious option, but would increase the mudguard stack which might limit it's use a little and a single mount point will vibrate more which might affect the durability.

Rack mounts are probably more common than bridge 'guard mounts too.

Well, yeah, even I'm not daft enough to just float cable in the air across to the bridge.
But see where all the bags are, that makes the seatstays the only easy spot to grab when doing hike-a-bike. No cable there = less chance of dumb hippy pulling it off the frame.

That's why I like my mid-stay position. It's (my) best of both worlds.

Then again, I'm more likely to be running a mudguard on the Tripster which opens up the possibility of a mudguard mounted rear light...

Drill! Drill!

These ones are single side mounted. Don’t think the vibrations are too bad. I’ve certainly not noticed it being an issue.

I didn't notice that, I assumed you were using both sides, hence my comments about mount distances.

Plenty of clearance between frame pump and cabling.

Thanks very much for putting me onto this, Paul from Fairburn Fabrications is making me one of these so I can mount my supernova to the mudguard point on the back of the fork crown. Such a niche market. World needs more talented people that make shit.
Machined out of a solid block of aluminium apparently. I love this forum.

Thanks, that's really helpful! Looks to be a tidy solution. Cheers all

No worries - glad you're getting some use out of it. I would recommend trying to make sure the bracket fits as neatly to the fork crown as possible to ensure you don't have clearance issues. I've got a fork with huge clearance but I can see how might be an issue for others.

@youramericanlover i'd reiterate my advice about applying the di2 guides. Thoroughly clean and dry your frame first then use a hairdryer on the frame to heat it up when you apply the sticky part.

Apparently can take a 2.1 inch 29er tyre up front (76mm wide between the legs). Can get a good few fingers in there with the guard on. Reckon it'll be OK. Thanks once again.

I've not been paying attention - did you not want to hang it from the bars for any reason? (handlebar bag etc?)

I'd like to have the option to have a handlebar bag however not sure if I'll actually get one.

No, not at all. The best bet would be to design a bracket to mount on one side, as you'd have no luck with any sort of standardisation.

Sounds like a German one. TBH I havent actually used that one in anger, but it is just a different beam pattern, it isn't less bright so as long as you set it up right you will be fine. Also, you can compare between the one on your tandem and on the Bowman, please report back!

Having had a little think I would say that mounting to one of the rack mounts would be sufficient for this, and avoid spacing issues. I have mocked one up from card and waved at various bikes, the only issue seems to be with bikes that have seat stays that come low (below top tube centre line) and a road caliper, as well as very small bikes. Would there be any issue in having a small run done of these? I'd imagine ~£10.
