Damn, these things are actually legit. I thought they'd ride terribly but they're pretty good, and great for cycling to work since you can throw it under your desk.

I live and work in London. Being able to put the bike under my desk is amazingly convenient, plus I can take it on the tube if it's pissing down with rain or I can't be bothered cycling it in. Or if I fancy a drink in the evening and don't feel suicidal enough to cycle home drunk.
/gag/fag here. I've thought of buying a Brompton or a Moulton to bring along with me when I'm time building, just so I can have a bit more variety than the airfield cafe when I go looking for that $300 hamburger.

Should I do it?

What'd you pay for it?
£885 for a black 3 gear with M handlebar.
Prettysure that smaller diameter = lower rolling resistance
Nice. What do you recommend? I'm used to road-style riding and would prefer something higher performance with 6 speeds. Which handlebar setup is best for that sort of thing? Bromptons seem like a weird world all their own.

Correction, the tracks have actually been damaged or paved over at some points (I only saw them around downtown).
The damage nevertheless doesn't seem so bad that it would be extremely difficuly to recover them. But obv SEPTA seems to have absolutely no interest in extending streetcar service. I've found some news items from last month when a study was published which recommends improving the bus network, and turning line 15 back to bus operation. This doesn't necessarily mean anything, but it goes to show that there's no push whatsoever for more trolley service. Sad

>Walker’s report also calls on SEPTA to consider abandoning the Route 15 trolley, which mostly runs along Girard Avenue, and replacing it with a high-frequency bus line, citing the streetcars’ inability to get around double-parked cars and other obstacles that frequently obstruct its path.
literally the only reason to consider abanding it is

>sounds like the real problem is, as always, entitled cagers.
indeed. afaik the route 15 conversion to trolleys hasn't been a huge success in regards to ridership, but I can imagine that the cost of operation can be economical if they last long (and they're already 13 years old since their rebuilding in 2005) and aren't too expensive to maintain, plus they are more spacious, comfy and enticing to ride than some shitty bus.
I'd love to see some numbers, but I'd bet that since the conversion to streetcar operation route 15 would have had its passenger numbers grow slightly.
>Walker’s report also calls on SEPTA to consider abandoning the Route 15 trolley, which mostly runs along Girard Avenue, and replacing it with a high-frequency bus line, citing the streetcars’ inability to get around double-parked cars and other obstacles that frequently obstruct its path.
What kind of complete fucking retards is SEPTA hiring to do a study? There was a similar study where I live last year, where parked cars also came out as a problem for the trams, so parking spaces are being scrapped because no one would even consider it to be the trams problem.

>The City of Philadelphia insisted that new Route 23 trolley rails be installed, on Germantown Avenue in Mt Airy when the street was reconstructed in 2008. SEPTA took that opportunity to destroy a key component of the Route 23 trolley: Mermaid Loop.
What kind of shitty fucking operator is SEPTA? Fucking end the contract with them asap and give the concession to an operator who isn't doing everything they can to sabotage the network.

Seriously haven't been this triggered in years
SEPTA is a public administration. They're sabotaging themselves, if anything. The point of this could be that SEPTA doesn't want to make it possible to recover those streetcar services, not necessarily because of an inherent hate toward public transport or streetcars, but because they're strapped for cash and don't want to be forced to divert funds to a trolley line which, on paper, won't do much to improve transit service. (Which begs the question why it rebuilt the street with tracks in the first place, though it could have been some formal requirement because otherwise it would have to change the lines status from "temporarily suspended" to "scrapped", or something like that. Fuck yeah bureaucracy!)

In any case, phillyanons here have often remarked on the massive retardation and lack of funding of SEPTA, considering that Philadelphia is a city with a reasonable level of infrastructure, as in subways, commuter light rail, commuter trains, streetcars and trolleybuses. I think that the city is being incredibly retarded over this, if they pulled a route 15 on route 23, as in recovering service with rebuilt PCCs (maybe some phillyanon could enlighten us on whether SEPTA still has unrestored PCCs lying around) it would be a huge tourist attraction, with classic streetcars running through the middle of downtown, while also being a great boon to locals using said route.

Rigid would work fine, but something that can run at least 38mm tires. You don’t need drop bars unless you want them.
Hardtail MTB might mean an all mountain HT with a 160mm fork at front or a XC race bike with 80mm front. Two different kinds of bikes. Assuming you mean an XC bike...

The main difference between those two is tire width and bar type. You're going to be fine with both.

As long as you use disc brakes, you can usually convert an XC bike to 700c wheels with narrow gravel tyres and you can usually put 47mm tyred 650b wheels on gravel bikes.

I'd go for a gravel bike with flared drops, but I am biased as this is my favorite bar setup.
I meant just a basic, cheap hardtail mountainbike. I don't know the different sub-categories that well
Then get any of which you fancy the most. You're going to be fine with both.

So what's the consensus on threaded BBs vs press fit? Is press-fit just a giant meme to get me to buy their expensive ass tools to remove cartridge bearings?
15 replies and 2 images omitted. Click here to view.
It's not the installation as such, though you can definitely fuck than up if you're a tool. It's the frames. The frame manufacturers have great troubles getting the tolerance of the bottom bracket shell right, and that causes some (many!) individual press fit frames to always creak and squawk after a while. Or kill bearings in no time at all.

Press fit is a solution in search of a problem, bringing many new problems with it.

Uh, no, that's completely and totally wrong, it's machined metal with cartridge bearings pressed into them. If it was just plastic they'd snap off the first time you stood on the pedals to sprint.

And after that there's an experimental train known as Dabusa which seems to be even more faster. It seems like the train was in China in 1950s, but then it's placed in a cave, locked up and buried, with no document left that could indicate where the train is at now
>if the T1 had issues with hammer-down forces on the rails
I don't believe this was the case. In fact, the reduced hammer forces were the reason the PRR opted for the experimental duplex locomotive designs in the first place.
>and violent wheelslip, I can only imagine what its even larger and more powerful big brother was like.
The wheelslip was the big issue. Like I said earlier, It's vague how much of it was from inexperienced train engineers going hard on the throttle, and how much of it was due to design issues.
The consensus as I've heard it is that the early PRR T1 models did suffer from incorrect equalization of the train's weight, and issues with the poppet valves, but that those issues had been all-but resolved through extensive rehab work near the end of the locomotives' lives, and the issues past that point were due to inexperienced crew.
The T1 was like the Ferrari of steam engines. If you opened up the throttle, the T1 would respond almost instantly. Thus when crewmembers used to smaller, less powerful locomotives were assigned to it, they'd often "peel out" since they weren't expecting the engine to be so responsive.
I don't know as much about the S1, but I don't think it ever received the modifications the T1 did. The T1 was a little less beefy, and yes, the primary concern in designing it was to make what was essentially a smaller S1, but by the end of the T1's lifespan, it's design had been greatly improved. I don't believe the S1 ever got the same level of attention.
They're both absolutely beautiful locomotives, though, and it's a shame neither type was saved from the scrap heap.

In the past I never did more than 100km a day (except for once where I did 200km and the last 50km where a nightmare)

My plan is to once a month get 200km a day tour. But I need advice on how to prepare and plan them

>>What drinks and provision should I take with me?
Water or coke without carbonation and bananas.
>>Should I do a break and eat lunch? and if what should I eat?
Something that has much fructose, like a banana.
>>how long should the break be?
Als long or as short as you want.
>>Do I eat when I get back?
If you want to, however I suggest a decent amount of protein.
>additional advice is welcomed.
Bring spares, get comfy and don't overpace yourself.
Start slow. Stop all the fucking time and take it slow. As you get stronger, go faster and stop less. Worked for me.

Don't bring soda. Water, fruit, energy bars (think Cliff bar), Gatorade if you must (something with salt is good).

If you're taking a real lunch you're better give it an hour to digest or it will just sit in your stomach making you feel sick until you end your ride
My other suggestion is consider aerobars or extra hand positions. If your ass hurts you need to find a better saddle. Fatter tires are good for comfort. Get 120 tpo schwalbe Supremes if you can afford em
>What drinks and provision should I take with me?
A sports drink of some kind with electrolytes in it and 100 to 200kcal of easily-assimilated carbohydrates, in a 16 to 24 ounce bike bottle per hour of riding, assuming your ride exceeds about 1.5 hours in length; if it's 1.5 hours or less then just water is fine.
If riding more than 3 hours it's beneficial for your drink to contain 5-6 grams of a protein source, too.
>Should I do a break and eat lunch? and if what should I eat?
I dunno, should you? Depends entirely on your level of fitness and the prevailing conditions. If you're riding for 3-4-5-6 hours you'll likely need to stop for at least bottle refills at various points. Also don't ignore your bladder, use the restroom when you stop to refill bottles, no need to torture yourself if you need to pee.
For what real food to eat if you take a break, I'd recommend fairly balanced but low fiber. A sandwich and a bananna is fine, and rehydrate.
>how long should the break be?
I dunno, how long do you need?
I wouldn't stop for more than an hour unless something's wrong. Half an hour for lunch for a long (3-4-5-6 hour) ride. You don't want to get too cooled off or allow stiffness/soreness to set in, makes it that much harder to get going again.
>Do I eat when I get back?
Up to 2 hours, just a snack, unless it's a normal mealtime. More than 2 hours (i.e. 3-4-5-6 hours or more) then focus on protein and fat more than carbohydrates, you'll have had plenty of carbohydrates while on the bike already.

Also can't stress enough rehydration, which is something you should be focusing on all the time, if you're riding daily and for long distances. Hydration has to occur far in advance of riding, not 5 minutes before you head out the door. Sip water all day long every day if you're going to ride like this. Be sure you're taking a good multivitamin/mineral supplement daily too so you don't just wash all the minerals out of your body along with that water.
Need more than just plain water for more than about 1.5 hour rides unless you're already in excellent shape and at a high fitness level and are trying to lose weight.

Coca cola is not a sports drink. HFCS is not your friend.
Bananas are overrated, and you still have to carry water, and what about electrolytes?

A better way to state this is 'ride at a sustainable pace'.
Better to eat low-fiber foods for your lunch break rather than sit around for an hour or more and get too cooled off.

Beginners probably shouldn't use aerobar extensions. Better to have traditional drop bars, they offer plenty of hand positions.

It's not really that you "lean" to the wrong side, it's more like pushing the bike down below you.
i fell for the brooks meme and genuinely believe that they are comfortable as hell
Stop making me think about it you're making me crazy
Countersteering can be done entirely through the handlebars. Buttsteering isn't going to work for extreme cornering.
Nope. It's neither shifting your weight nor pushing down. Steering into the opposite direction is the only way to initiate a lean. However, both shifting your weight and pushing down appear to have the effect of initiating a lean due to the fact that they cause the rider to unconsciously push forward on the handlebar (i.e., in the opposite direction).
Every rider (motorcyle or bicycle) countersteers to corner at an speeds above walking speed (i.e., when the gyroscopic effect is present). But some people do it unconsciously and most don't know how it works.
Many riders who realize for the first time that they don't have to shift their weight at all or push down on the handlebar to initiate a lean (but rather just have to steer into the "wrong" direction initially) are quite surprised.
