What are my options for replacing pic related? The barrel thread snapped and I don't care to fix it. It's 160mm rotor, I don't really care about stopping power, I regularly ride caliper/v-brake/hydraulic brakes and it makes no difference to me.
So cheap options are preferred. Are v-brake adapters any good?

I used to do it all the time when I worked downtown. alu road bike on mavic with 23s. the hard part was hopping up. gotta get a lot of speed and road bikes don't want to hop as high as mtb. but if you have to speed and ups it'll go just above curb height. of course, Matryn Ashton could hop over a fuckin chair, although he would lower his seat.

>>
>>1989503
I imagine if you were to take that spray bottle and use it on a piece of cloth before tossing it on the campfire it could have the potential to change the way the cloth is affected by that fire? are they really dumping it on the actual flames, or on the stuff that's about to get eaten by the flames?

it's primarily used to create boundaries that don't burn to contain the fire, using it for direct fire fighting is a little wasteful, it's an agent better utilized strategically than tactically

The Civil Rights Act / EEOC creates an effect I call the Shaneequa Event Horizon, where because sassy black women are impossible to "out diversity" (because they vote 96% for Democrats) any federal agency will eventually fill up with them until the agency fails at its core responsibilities and they get outsourced. If this happened to Amtrak and passenger rail got deregulated we'd see a 10x in available trains.

Ebikes should require registration and an active insurance policy. $15 million in liability insurance per bike, minimum, to cover the average damage they do every time they explode. That doesn't even cover the loss of life but it's a start. Possession of an unregistered ebike or unregistered parts such as batteries should be a mandatory minimum sentence of 5 years in prison and being banned from touching another ebike ever again. Second offense is life in prison, you can't prove me wrong.

I've come round on ebikes and battery electric vehicles in general OP, I agree now. Not only are the batteries dangerous and less energy efficient than gasoline/other ICEs, they let people think that they can have personal transportation and still help reverse/lessen climate change, when the only real change will come with a heavy reduction in personal vehicles and greater focus on public transit which can be powered by energy transmission from static generated electricity (ie. third rail or overhead wires fed from nuclear and renewables).
The government should start clamping down on electric AND traditional ICE vehicles. Stop subsidizing fuel suppliers and auto manufacturers (ICE or internal), heavy penalties for companies found to be using lithium sourced from human rights violating countries (and in cases on countries relying on forced or underage labour, military intervention if necessary).
>>
>>1989353
because everyone in a position to do something realizes that the whole delivery app gravy train is a major force in gentrifying the cities, if you ban the ebikes you destroy the profitability of these apps, which eliminates the well paid tech jobs, which suppresses demand for the cool gut renovated loft apartments in old warehouses, which is terrible for property values, and the whole house of cards falls down

basically it's better to deal with some fires (which pretty much have their impact limited to brown people anyway). it costs less, it keeps the firefighters busy doing something related to their jobs instead of getting into brawls at irish pubs and using their union connections to avoid drunk driving arrests, and it might even clear up some precious land to build the next colony 1209

Discuss bike apparel. Engage in catty tribalism between "lycra lout aero fred" and "practical normal not-a-cyclist' (actually still marketed to cyclists but with reverse psychology) apparel. Boast of your metric century (not a real century) wearing just jeans and a t-shirt. Conveniently, there is no strava of it but it totally happened I swear!

heh, i live in fl too and have been using some el cheapo sunglasses of unknown origin for years.
but ok i was wrong, with the tint it brings non polarized to $32 over $45 for polarized because tinting is included. it's just the lenses themselves that are $16 vs $36. but no uv protection? dunno. i would assume my current ones don't have that either so i guess i probably won't notice a difference.
>>
>>1991944
Depends on your environment and riding conditions, I don't have a pair of polarized prescription glasses but I used to have a set of polarized Oakleys that blocked a lot of glare reflecting off car windows and glossy paint on clear high brightness days. It's useful if you're sensitive to glare.

I wasn't able to find anything definitive. But it is unlikely that train lengths in the EU are going to go above 750m ( about half a mile ). At the same time there is an effort to raise the permissible axle load system-wide to 25t. This puts the upper limit of train weight at about 5000t. Thus with a safety factor of, say, three you have an upper limit of 15000t.

>>1990983
Janney is not 'superior'. It is merely semi-automatic. The new euro coupler will automatically couple digital signals for electric brakes and, I think, also air lines. It makes it superior to both Janney and SA3.

Granted - it is at least 50 years too late.

>>1991113

why are they backorders though? Airbus has been around for awhile and doesn't have the issues like Boeing does?
>>
both sides of the duopoly are shit. Boeing is The poster child for putting the cart before the horse and orienting their entire business around stock buybacks and suffering predictably for it.

but airbus is also retarded, just perhaps in a less criminal and/or malevolent way. even Boeing, in the throes of some sort of actual collapse, is better at efficiently marshalling its resources and reading the market. EU industrial policy also wards off private investment interest and public coffers in Europe can only do so much when Germany is mired in stagflation hell.

still overall I think Europe will be just fine and interventionist policies will pay off, but you will always have airbus gimped by its significant administrative and bureaucratic bloat.


aviation needs competition from somewhere that isn’t china.
