Im looking to buy a fixed gear bike but most seem to be cheap fashion accessories. Anyone know which brands generally make the best fixies? Are brands like retrospec or 6ku any good?

You want a 'chromoly' steel frame & fork. Or, for something a bit lighter and racier, an aluminium frame with a carbon fork. Like an aventon or a fuji track.

Retrospec & 6ku both seem to just offer high-tensile 'hiten' steel (extremely low quality, heavy and dull) and aluminium frames with aluminium forks (low quality, harsh). Or the steel isn't even specified, so I assume it's hiten.

On a bike you have to mash up hills you really want a good frame, and that makes it worthwhile upgrading over time too.

Otherwise yeah, if you're only prepared to spend $300 or less, you're gonna just end up with a cheap fasion accesory, not a good bike. Unless you hunt out a good deal on a high quality old road bike with horizontal dropouts and a fixed gear wheelset and convert it.
no, because grant is too thick in his head to think a bike can be anything other than some 40 lb overbuilt boat anchor with chainstays that put the rear wheel in the next zip code. please don’t misunderstand that i think he makes bad bikes or that his philosophy of what makes a good bike is somehow wrong, there are infinite ways to make a good bike. that he thinks there’s only one way is why he fails.
$5.something for a KMC 7 speed at walmart.com with free pickup, Amazon even with prime doesn't let you ship free and counts it as an "add-on item"
Do you even own a Rivendell? I’ve built one up (one of their Taiwanese outsourcings) and the quality was disappointing for a $1,000 frameset. The driveside rear dropout had so much paint slopped on that I had to take a file to it to get any of the wheels I had laying around at the time to fit. The headbadge was falling off, the FD clamp was situated right between the seat tube’s bottle cage taps, requiring spacers to mount a cage, and there was a large buildup of clearcoat on the bottom of the BB shell. All of that just tells me the QC is piss poor, especially the rear dropout and bottle cage/FD situation. And it wasn’t a problem with using some weird sized 58t chainring, it was a 50t outer ring which caused the interference. Rivendell is highly overrated in my opinion, and Grant’s senile rants don’t help their cause.

who else loves ''small'' blimps over large rigid airships?

I am an LTA enthusiast and my interest is primarily with blimps, gas balloons and semi rigids.

I've never really believed in super large, massive, rigid, transatlantic, hybrid, cargo carrying pipedreams

One very important feature of lighter-than-air craft which confers upon them a superiority over heavier-than-air craft, namely, that an increase in the size of airships gives greatly improved efficiency. The reason why in an airship the efficiency ratio is improved with an increase in size, whereas in the airplane it remains at best stationary, is due to the fact that the airship derives its lift from volume, while the airplane derives its lift from area. Now, in either case what may be termed the unit of lift, cubic feet of volume or square feet of area, exerts only a definite lifting effect; in the airship this is determined by the specific gravity of hydrogen or helium, and is therefore immovable, whereas in the airplane it depends upon progress in design, and is thus still open to improvement.

This fact may, in a certain measure, work out in favor of the airplane, but there are other factors which actually limit the practicable size of heavier-than-air craft. One of these is that while the lift of an airplane theoretically varies with the square of linear dimensions, the weight of the wing structure per unit of area does not remain stationary with an increase of wing area, but increases, because the larger wing structure must be made proportionally strong. Consequently, a size is eventually reached where every additional square foot of surface weighs as much as it can lift, so that beyond this size there will occur a marked reduction in efficiency.

The best way to increase the speed of the Zeppelin is to increase its volume. The greater lifting power permits heavier motors. Air resistance does not increase in the same ratio, because it varies with the square of the balloon's dimensions, whereas the ascensional force varies with the cube. So when the length and width are doubled the resistance of the air is quadrupled, while the ascensional force is increased eight times.
“The world is estimated to have over 1.4 trillion cubic feet of helium reserves. At current rates of production, along with conservative growth rates, these reserves could produce helium for decades.”

“There is no shortage of helium on the planet; however, this helium will only be produced as a byproduct of natural gas or LNG production as these resources are exploited by energy companies.”

1.4 trillion / 10 million = 140 thousand

There is enough helium on earth to fill 140 thousand, 300 meter long airships. (The Hindenburg was 245 meters.)


So there is enough helium on earth for atleast a few large airships. The Hindenburg class airship was never intended as the final size for airships. In fact, the ideal size of airships is about double the size of the Hindenburg ( it would be able to carry 10 times the amount of passengers at this point ).

But only a large government would have the power to do this. Is it impossible to build a 500 meter airship? Of course not. The largest sea-ship currently is about 450 meters long.

The Romans did make some canals but nowhere near of the length and number that came later. Canal construction kicked off in the 1600s, they had their heyday in the 1700s and enabled the industrial revolution to happen, and started to go into decline around the mid 1800s when trains took over. They were still used for commercial transportation as late as the 1990s. Some abandoned canals have been or are being restored to service, many have been filled in and built over and are gone for good

I'm totally rambling at this point, but here's a nice pick of the cockpit. From left to right: your controller, the old school up right, manual kind; direction handle, in a tram like fashing this is fixed and not a "key"; electrics box, containing the tram's driwing light switches, the bell and point turning magnet controls; your standard Westinghouse brake; rotary parking brake and sand pedals. Behind your back at the roof there would be cabin light and heating resistor, controls, and the main power switch which also doubeles as the cab selector. You don't get fancy things like speedometer or automatic windshield wipers.

Now I said this tram is bidirectional, but as Helsinki is 100% unidirectional system, some concessions were made: the B-cab doesn't have that lights control box or sand controls. Still better than that other heritage unit where the rear cab is 100% dummy.

Fair. Here's a better link



>About 75 per cent of the tram network operates on shared roads with other vehicles, meaning trams are often vulnerable to traffic accidents on the road.

>Up to 17 per cent of journey time on Melbourne's trams is spent waiting at red lights, compared to just 2 to 5 per cent by international standards.

Like I said, we’re on a government contract so we’re not working for a drill rig, they’re far as fuck in the middle of the pacific

The majority of the passengers are government technicians who’s entire job is to hack shit, they’ll get through pretty much anything we can put up senpai, it’s also not like they really abuse the internet or anything, there’s just so many people on the boat and our company/the charterer doesn’t want to pay for more bandwidth than what they’re already paying for.

Absolutely disgusting. Transit needs to go where people go. Not where cars go. Denver messed up big time which can be seen in how few people ride their system per mile of track.

It does run to Brisbane/Dubbo/Melbourne/wherever. It's just that it stops at pretty much every station along the way. If you're lucky you'll average 70 km/h as per timetable.

Less than a week in service and it's broken already. Pantograph for charging got stuck, and even worse the article confirms that it will have to charge at every stop. On the bright side, it appears it will only have to stop for closer to one minute a charge instead of two.

It's only 3km long so there aren't very many people who would use the new tram in the first place. It replaced a perfectly good train line so now instead of having a 1 seat commute to the CBD, people have to change.

Really, V/Line is stuck in an awkward position of having to cater for both outer suburban and regional passengers. Geelong line with Tarneit/Wyndham Vale, Ballarat line with Melton/Deer Park pax etc. Additionally, without quadding the lines to the north and south east non-stop V/Line trains will be stuck behind Metro stoppers to Craigeburn and Pakenham. Until suburban electrification is extended "long distance" trains have to share the downsides of short distance ones.

Keikyu Haneda Airport Line extension capital investment surcharge to be removed from 10/1. Shinagawa -- HND Domestic Terminal fare reduced from 410yen to 290yen.
Speaking of Haneda Airport, it appears that the first of the three routes of JR's Access Line will be completed by around 2029. The East Yamanote Route which will connect Tokyo Station to Haneda Airport will begin its environmental assessment (3 years) and construction will take around 7 years to complete. The timetable for the other two routes (West Yamanote for Shinjuku and Rinkai for Chiba) are currently unknown


>Not just put both news bits in one post

For those who are curious, the 170 Yen surcharge for the Keikyu Airport Line was implemented when the new station opened in 1998 in the new domestic terminal. It appears that Keikyu has recouped around 75% of the initial investment so they decided to reduce the surcharge from 170 Yen to 50 Yen
