It seems to me that blinky lights are easier to notice than steady lights. Perhaps they are harder to track and gauge where they are, but I can't see how the difference is much. In any case, you get the best of both worlds if you use both types of lights at once. I often run a blinky taillight and a steady taillight.

I agree that a blinky headlight is silly at night. Well, some use them, but I have no interest. It seems useful in the day. The Cygolite headlights have a "steady flash" mode that gives a burst of high intensity while otherwise staying steady at medium intensity. I find I can ride with this, though it is a bit distracting to me.

I'm glad the German laws led to the development of excellent lights, but I think the laws are too restrictive, and I'm glad we don't have similar laws here in US.

Yeah most LED headlights don't use anywhere near the full 2.4W budget, they burn it off with a resistor. It's an artificial limitation to make room in the market for brighter and more expensive models, which I think is another thing that needs cracking down on.

Horse, I'm thoroughly enjoying the electrical science you're providing (honestly, you are demystifying a lot of things in short order) - but kindly keep the politics and judgement calls for a different thread. I deal in the muck of US bicycle advocacy every day at work, and I really don't want to get that sort of heartburn here. I created the build thread for mutual enjoyment, not for A&S.

The word to look for is "standlight" or "steadylight".

I don't think it's a regulation thing as I have bought models without a standlight (Axa) in the past and they continue to be sold in some places for really cheap bikes. Think €5 dynamo lights.
I did those tests using the LimeBike's light and the two generator hubs today, and - sure enough - the Blaze-Lite equipped on it has the built-in capacitor. It holds it's brightness fairly well (it's still feeding the LED a tiny bit of power right now, 20 minutes later).

That said, I also checked the Nexus 2.4W hub against the Chinese 3W. To be honest, it felt as if the 3W was a bit brighter. Not enough to make much of a difference, but a difference nonetheless.

Of note: The Lime's LED taillight is completely dead.

A few bits of progress tonight - starting with the fork. Headset nut was on tighter than anything I'd seen in ages, and I had to put a pair of dropout alignment tools in the fork just to get enough leverage with it.

The crown race wasn't seating as tight as I'd like, so I ran it through the J.A. Stein knurling tool. Much better.




Got the fork in the Park alignment tool, and will take care of spreading it to 100mm (from ~85mm) during the week. Will also have to open the dropout slots a tad.



I've decided to go radical anyway - rear brake is going to be the black Tektro 900A (which fits quite nicely), and I have a black 800A on order from Japan (one of the Arai-branded ones off eBay). Apparently, I can't get a rear 800A in black anyway.

I decided to do this when I couldn't convince myself that a silver front dynamo hub would look good with that huge, black G9 hub in the back - so I also ordered a nutted, black, Shimano DH-3N31-NT for the front:




The way I see it, the 1980 Raleigh Sports is so far removed from it's heritage that building it up with some decidedly modern touches might suit it. That, and it needs something to break up all the monotony of silver - even though there's a certain monochromatic theme going on here. 50 Shades of Ralgrey?

In continuing with that theme, I'm planning on getting a pair of these too, which came up in the 1954 Raleigh Sports discussion. They're not period accurate or even accurate to the mid-logo grey grips of the 1950's, but they look right and play into the black theme:







Incidentally - this ought to give more than a few of you the willies - I'm considering drilling a small hole in the steerer tube to route the dynamo wiring for the back. Straight up the bottom of the crown, through the steerer, and out through the downtube and BB shell.

The steerer tube on this bike feels ridiculously thick and heavy, so I'm not convinced a 4mm hole that's nowhere near the stem wedge is going to be the end of the world. Nevertheless, I'm considering having the (proposed) hole reinforced with a suitably-sized washer soldered/brazed to it. Should be more than enough to ensure that things will remain safe.

...and now for the soft porn of British C&V.

Chapter One: The Pastor Visits The Shed
It began on a forlorn New Hampshire afternoon. The sky was overcast. Winter was in the air. The cycling season would soon abruptly end in the mountains of northern New England. Gray clouds hung low upon the bald granite summits, which had been scraped cleaned eons ago by dirty glaciers riding hard upon their surfaces. Subsequently sooty forest fires insured their continued 360 degree views. Yet it was the power and forces of a desperate mother nature which had shaped this darkening landscape over the course of many eons--- which remain shrouded in the mysterious fog of a land long unwatched by human eyes.

On that day when gray sleet pellets annoyingly announced their chilling intentions with an occasional "whack-whack" to the Bell helmet, the pastor trundled his way up the broken asphalt drive from the main road circling the wind chopped lake. There the docks had all been pulled and stacked neatly away from the shoreline. The boats, kayaks and canoes, were wrapped for their long winter naps. Steely ice was beginning to cluster and grow around boulders standing proud from wind whipped waves. Wrenching season was descending with a vengeance.

The pastor was heading to the fabled village "stump dump." Here the citizens came to make deposits; no longer functioning appliances, yard debris of branches and dead leaves, spent propane canisters, scrap metal, and the odds and ends of long forgotten, neglected, and no longer needed basement, attic, garage, and shed treasures. These latter things were first placed in or around the shed. The pastor checked here first.

There was nothing special about the shed--- itself. A wooden structure built by civil servants from scrap or repurposed spare lumber. From the inside gaps between ill-fitted boards admitted feeble late fall sunlight--- the little that could permeate the deepening overcast. They had probably constructed it during an in between time--- plowing and other road-agent work. Despite its lack of pedigree--- the shed contained treasures--- or the possibility of treasures--- none the less.

To be continued....

I know the story...and I'm already eagerly awaiting to hear you spin poetic of the rest in Part 2...
