salmon tends to work pretty well
 
roger
 
it just wears out faster
 
found sweat deals on tires, but whenever i chose reflective sidewalls they cost more than a tenner :-(
I wonder why Schwalbe even bother to make tires without reflex strips.
 
good amount of the market likely doesn't care
its nice to have but i wouldn't pick a tire entirely on that
 
can keep those unsightly spoke reflectors off the bike and still have a legal one.
 
12:55 AM
I might splurge and get a lovely brass coloured bell.
 
bell.....pbbbfttt.....AirZound that thing
plays the arrogant American card There is nothing like a refillable airhorn to blow people right out of your way.
 
there are Japanese hand painted brass bells.
Judging from the price, master bell smiths, with a tradition going back thousands of years make them after meditating for hours in a forest. They are then painted only by the most beautiful women, with the nimblest fingers, and adorable silken cloths in painstaking, tedious, work.
oh bugger, forget what i said. i just stumbled over a flat pedal that costs 250 euros!
must be made out of cast unobtanium.
 
1:27 AM
we don't have spoke reflectors as a legal requirement
 
spoke reflectors are awesome and you should fit them
get rid of those yellow crap things
the white ones that look like straws, clip onto your spokes
Much more reflective and from all directions.
 
just looking at those
 
36 pieces for a fiver. (I think there must be some lying around in the parts bin somewhere.)
 
And you can use them to help balance a wheel a bit
 
2:25 AM
I don't have reflectors on any of my bikes.
But, for every reflector I throw away, I buy a light. Thus was born the brown of dorkdom.
Cars don't have reflector requirements, they have light requirements, and bicycles should as well.

yeah - but you're not allowed to point lights sideways
Round here cars do have reflector requirements, but they're pretty minimal.
2 square inches of red reflector on the rear , within 150mm of the corner. So that's integrated with the brake light housings.
 
In the UK cars have reflector requirements.
 
yah cos parked cars have no lights.
 
yeah
some bike lights come with side visibility do dahs
see light and motion
I'm also guilty of binning all my reflectors at the first chance
but I leave the cool little light that clips into my seat on all the time
until they disintergrate
 
different countries have different rules.
Here, blue lights and green lights are illegal on the road.
red lights must not face forward and white must not face backward (unless they're reversing lights)
 
4:45 AM
sensible
wish I was visiting germany soon, I need some good lights
who's is the bike light database?
I forget

Car light become increasingly intense with the migration to led and lasers. Weaker lights lose conspicuity.
There are at least three factors that prevent bike lights to keep up with this:
Legal: in some jurisdictions there is an upper limit to bike illuminance. There are no upper limits for cars, afaik anywhere.
 
I like a high light, a handlebar light, and a low light on the fork. I also use wheel spoke reflectors as already mentioned. On the rear I use a small blinky on the helmet, a larger flasher in the jersey pocket, two seat post lights, a blinky on a chainstay, and strangely a large red torch strapped to the right chainstat that illuminates the rear cassette and a pool of road below.
@gs There are all sorts of restrictions in different areas
In NZ can have 55W lamps on either side as dipped beams, and 110 W (I think?) High beams
 
Size: providing energy sources and light reflectors comparable to cars would encumber bikes too much.
 
or the equivalent in LED land.
well... no actually
a decent Lithium something battery can run some pretty intense LEDs for several hours
and reflectors are redundant with LEDs and shaped optics.
 
Direction: cars also achieve such high Illuminance as their lights can be directional. Bikes need to cover most solid angles in the road plane.
 
well kinda
 
9:55 AM
Reflectors are a solution to all three problems.
 
I have an intense focussed beam from my head light. It goes exactly where I put it, and at night time its great for lighting up things. I have more "be seen" lights. Sometimes I also fit a bottle light, which is a 12V SLA battery in a drink-bottle. That runs two 12V LEDs and provides huge short range illumination.
 
Reflectors reflect directionally, they outshine all other passive objects, and are light enough to cover full solid angle.
There are power limits and angular limits to car lights, not light flux. More efficient and bundled lights increase the latter.
Soon laser headlights will come, there's no keeping up with them conceivable, unless we get the same amount of sensors and computing in our bikes.
They use environment modelling to light exactly where needed in front of the car. Excluding wind screens of other cars to avoid blinding.
@Criggie post a pic! How long does it take you to set that up?
 
10:32 AM
A pic of my lights?
Its summer (late summer) so I don't even know where they are.

Reflectors are passive and dangerous because they can suddenly make a cyclist "apppear" to cars when the car is finally pointed at them. Drivers are used to reflectors on non-moving objects like signs and mailboxes. Having them on rarer moving objects conflicts with the algorithms driver minds develop. Having lights on a moving object fits them into the algorithms already established by the drivers mind.
Would you rather be perceived as a mailbox that suddenly appeared, or another vehicle with your own lights which was detected and anticipated some distance off.
At this point you can have a headlamp that will produce more light than your average vehicle headlight and run for hours on 4 AA batteries. Cyclists no longer have an excuse for not being lit.
Wearable lighting surpassed car lighting some years ago. Cars don't have a power supply problem, so most of their lighting is far outdated compared to newer LED headlamps and cycling lights. There is no reason for car lighting to evolve. People put LED lights on their vehicles for looks and longevity now, but not because they are brighter or more efficient than older style lights.
The light setup I have gets run on low when I am around cars and other cyclists and provides roughly the front light (or slightly greater) than an automobile. It provides far more rear and side visibility (LED rear blinkies) than an automobile has.
On high it provides far more light than a stock automobile is capable of, roughly equivalent to after market cannon LED lights that I had mounted on my van. All of that will run for hours (or days in the rear blinky department) on batteries I can hold in one hand.
Discussions like this upset me because the laws (at least here in the US) allow cyclists to be stupid. Cyclists (by law) have been allowed the same rights as vehicles to the road. However, they haven't been forced the same responsibilities as vehicles have (lights for visibility and safety equipment). It's typical of ignorant and entitled American thinking. "I want mah rights!" (but no clue as to the responsibilities that should come with that).
Sorry about the early morning tirade.

If I was interested in building a commuter bike with road aspirations, what frames should I look at aside from the Surly Crosscheck? My current bike is aluminium and I like not having to worry about the paint getting chipped. Internal cable routing (brake, gear and light) would also be great.

I dunno. Same reasons cars don't have both I guess.
Sorry to have kilt chat todai.
@RobertAtkins Why not just buy a road bike and get a set of less racy, stronger wheels to commute on?
 
11:18 PM
Cars do have reflectors, so do lorries, trailers, police cars, motorbike riders, etc.
 
11:51 PM
In most parts of the world seeing reflectors on a bike is also not something that would surprise drivers but rather is expected.
