Cygolite Metro Question

Hello

i mainly ride roads on my commute home, not the best roads mind you, but it isn't gravel or dirt roads. in any case, my headlight moves on its mount sometimes. and although i tightened the screw, it still comes lose to the point of annoying me.

i feel like maybe i missed something when i got the light, like maybe i forgot to put something between the handlebar mount and the part that actually secures the light, something to provide friction.

has anyone experienced this and if so, what was the solution?

the light is a cygolite 360 and i dont need to upgrade but some of the reviews i've been watching have me curious about getting something more high powered like a 900 lumens flashlight if only to see how bright it is...

Same thing with mine...until I really tightened the swivel screw on the mount. It's still swivels, but takes a lot more force than before. It won't come out of alignment from bumps on the road.

I have a cygolite 800 and usually use it at the low setting (500 I think).

Unless going off road or something technical, then it is nice to turn it up. Biggest benefit is that it lasts longer.

And...

For cycolites
I like to keep old innertubes around that are too used to patch.
I take one and wrap it around the handlebars to give the cycolite a little more traction. Mine doesn't move at all like that.
The 850 also came with little rubber strips to go around the handlebars that do the same thing. Either way, the longer the rubber the better.

Lots of clamped accessories have traction problems. Over tightening in an effort to solve this can crack the parts.

A better alternative is to try to increase friction. Sometimes, it's simply a matter of an alcohol or acetone (not nail polish remover) wipe of the bars and clamp. I prefer to use latex or PVC sheets, cut fro balloons or dental dams begged from the dentist. These offer much higher friction than the molded inserts on most lights.

The mount was recently changed. The old one is perfectly circular with the rubber on one side having 2 small holes that fit into 2 nubs in the bracket shell. IME this is the one that is more likely to move around.

The new design is more ovalized clamshell design with what feels like a grippier type of rubber and a much longer skinny plastic knob on the nut. The nut is easily over an inch long. In my experience, this one doesn't move.

As to the light vibrating or rotating left/right: a strip of electrical tape inbetween the upper/lower halves and retorquing the screw is a good fix.

For point of comparison, 750 lumens is on par with a cars high beam. I have 1 old 800, 2 newer style 800's, and an 850. A headlight of that power is really only suited for alone in comlete darkness, but amazing to have and well worth it. I only ever use that kind of power for a short 1 mile twisty downhill on my morning 3am commute. (restarting soon!) Thr rest of the time it's set to "low" or flash mode.

An 800 lumen in flash mode even in broad sunlight COMMANDS drivers attention. I certainly don't see how you could need more. But would recommend you be sensative to others in regards to ambient lighting conditions. I turn flash mode, or sometimes the whole light off when on MUP

I have a small patch of duct tape on the bottom third of the bar. It helps with the friction of my rubber strap mount, so it stays in place better. The tape stays there all the time, but I take the light off if I'm riding in the daytime.

I have a cygolite 550, and love it. If I understand the problem, you have too much left to right play on the light, and it goes off from center too easily? If that is the case, I had the same problem, but tightening the screw on the holder piece solved it.

In terms of brightness, I ride the mean streets of south St Louis, and love the full 550 lumens that it gives me, even though, with streetlights, I don't necessarily need it to see. I wouldn't want to go any lower, but I also find no need to go higher.

I, too, tightened the screw to keep it straight. I also used a piece of old inner tube to keep the clamp from moving around on the bar. It
didn't do it at first. I wonder if by over tightening, I was pulling out the threaded insert in the clamp.

The old ones only worked if the bar was just the right side. The new ones are marginally better. But, if that little rubber piece falls out, it certainly doesn't stay in place very well.

Helmet mount on the other hand, rocks. I have a 500 and an 850, but one of the reasons I got an 850 was the free helmet light. ONe lite on the bike (for depth perception) and one on the helmet (for peripheral perception)

Interesting. I have 3 of the "old" mounts and have no problems with the light swiveling unless I bump it with my hand. The screw is easily tightened to keep it pointing straight ahead. I've also never had any problems with the mount moving/rotating on the bar. IMHO it's a great mount design. Much better than anything else I've tried.

I like the light and the mount. But I didn't want to crank down on that screw and break anything. Cygolite had been very good about sending me replacements whenever I needed them so I like their company. Not knocking any other business but this is the first I tried and I liked the service so kudos to them.

Also I read somewhere else that someone had put loctite on the screw to keep it tight in the mountil. I'm thinking I'm gonna take it apart and put two layers of electric tape between the light mount and the bar clamp and see where that takes me.

That's exactly what I do as well. I lost one of the rubber spacers so now it only stays tight on the thickest of bars.

Oh, no, don't get me wrong. It's a good mount, likely to move doesn't mean will move. By that, I mean up and down rotating about the bar. The old mounts really are good, but I think the changes on the new ones make it even better. The minor tolerable weaknesses were addressed and improved.

When I first got the light, it jiggled, vibrated, and flopped left and right. Tightening the screw helped, but didn't solve the issue. So a square of electrical tape got sandwiched in between now it stays where I point it.

My guess is it just happened to be the injection mold. All within tolerance, some with a higher in deviation from nominal.

Maybe we have different definitions of "tight"? In any case, I'm happy enough with them to own 4. So that ought to say somethin'

On 2 of my 3 mounts, my Cygolite Expilion would wiggle around inside the little channel holding the light. They weren't nearly as tight and solid as the original mount that came with the light when I first bought it. I thought one was defective but the 2nd one they sent me had the same problem. So I placed a small square of Velox rim tape inside the channel where the light slides in, and now they're all rock solid.

I have 2 of the Cygolite Metro 400s, and the mount is terrible. It stays put on the bar just fine, but the screw that keeps the mount pointing straight, that is a whole other mess. One of the mounts is just about broken after tightening it, which did nothing. The first time I took the light off, the mount came loose again. The second is alright, but it feels loose. My plan is to take some super glue, and just glue it down so that the light has no side to side rotation.

I compare this to my Niterider Lumina mount and it is night and day. Similar style mount, but Niterider has it nailed down and Cygolite is failing miserably, because on the opposite end, light vs light, I like the Cygolite a lot more than the Niterider.

I've had to tighten the screw a few times on my Cygolite mount (on my main commuter bike), but no more than a couple of times per year. It never gets to the point where it's just flopping around, but sometimes it will loosen to the point where a solid hit from a crack or hole in the road will make the light shift slightly. So I just snug it down and it's good for another 6 months or so.

You mean it's moving laterally? My Cygolite Expillion does this; the adjustment range is not that drastic though so I just live with it. I would imagine that some kind of shim could be wedged in between the swivel and its base, maybe something resistant to moisture like a plastic card.

I think something similar is what I'm going to go for. Just haven't had the time to take the mount off the bike separate the two pieces of the mout and what I can do, besides glue, to form a more stable base.

The wiggle is lateral however, I can foresee stripping this screw and make breaking pieces somehow if I crank down on it.

So far I have to tighten at least once a week if I ride all the weekdays. By Friday itso going left and right pretty good.

If you mean that the light is swiveling around the handlebar, make sure the insert is inside the mount. If so, and you're mounting to bare bar (not over bar tape), try wrapping a scrap of inner tube or electrical tape around the bar underneath the mount.

If you mean the light is swiveling side to side, especially over bumps, try tightening the screw on the mounting plate. On both my cygolites, this worked -- for a while :0 Try removing the mounting plate and putting in a washer cut from an inner tube. A quicker and easier fix is to loosen the screw slightly and wrap a cut rubber band under the mounting plate. Tighten the screw, and trim the rubber band. This fix has lasted 3-4 months of winter riding for me.

good answer


you can also get a long rubber band if you wanted and run it under the handlebars hooking it over front and back. I found that cuts down on the swivel. I only used it off and on... mostly off. I also tighten it every six months or so. I think cold weather the plastic contracts a little and it moved back and forth a little.
