comment How does my tire pressure effect the tire's maximum load?
You can reduce the stress on the wheels and tires by properly moving your body to account for bumps, you have a front shock, so you can be less careful with the front, but try to move your weight to the back (or even lift the front wheel a bit) as you approach a bump, once the front wheel clears the bump, shift your weight towards the front of the bike.

comment I keep getting flats
@Criggie Actually I have a local MEC location as do many other Canadians. I have always found them to be quite helpful and knowledgeable when dealing with bike problems. They are one of the few local stores that doesn't switch over into full ski mode for the winter. There are other locally owned bike shops with similar pricing in my area.

comment I keep getting flats
Very much agree with this other than your pricing. MEC has a wide range of good quality tires and only the most expensive stuff comes close to your $80 mark. There's a lots of quality road bike tires in the $40-$60 range including some very puncture resistant tires like GatorSkins.

comment Flat handlebar caliper brake compatibility
I believe they would be compatible with any STI levers. Although you need to make sure you get the ones with the right size of clamp for your handlebar width.

comment short cranks for new Brompton JIS bottom bracket
You probably won't see a lot of crank arms sold individually without the chain ring unless you get into the very high end. So there isn't much savings to be had from buying just the crank arms. As far as selection goes, look for stuff made for fixies or single speeds. There's a lot of stuff available with 165 mm cranks because shorter cranks are needed on fixies to prevent the pedals from hitting the ground as you go around corners.

comment Chain hops off cassette sprockets when I stand-pedal
If your bike has a freewheel as opposed to a cassette, the problem could be a broken axle. I had an old bike that would have the chain slip on the cassette. I didn't realize there was a problem until quite a bit later with the axle. Everything looked fine even with the wheel removed. Freewheels have a tendency to break axles more than cassettes because of the way forces are distributed.

comment Is it ok to extend/straighten legs fully while pedaling and will it give me maximum power?
1 hour vs.10 miles doesn't equate. That means that you are only travelling at 10 miles an hour. Unless you are doing technical mountain bike trails, then you should most likely be covering more than 10 miles in an hour. Adjust your bike position so that you are in the proper position and work on your fitness. I'm sure if there was something to be gained by putting your legs at full extension then we'd see track racers doing it, especially in the shorter distance track events, but since we don't see it, I'm going to say you should just follow the general body positioning advice.

comment How to measure and cut chain
Everything seems to be shifting fine enough. I don't recall if I tried putting it in small-small to see how much slack there is, but I have a triple so I only really go into the small ring when I'm climbing significant hills, in which case I'm going to be in the top half of the cassette.

comment How to measure and cut chain
Very much agree with this. I recently put a new chain on my bike, and even though I have a small cassette (23 tooth), I just ended up putting the chain on and attaching the power link. Last time I did it I took a few links off the chain to account for the fact that my large-large combination isn't that big, but I figured that taking the time to shorten the chain is more trouble than it is worth.

comment Bottom bracket feels rough, should I replace it
It was pretty rough last spring when I took it apart, but just decided to put it back in. It's 4 years old now, and easily over 10,000 km so it's probably due for a change. Is there anything I can do to care for it better to make sure this doesn't happen again? I didn't really do much to the current one.

comment More or less skid patches for winter tires?
A good idea would be having a front brake on your bike and avoiding the skid patches altogether. A good front brake will stop you much faster than skid stopping or a rear brake, and save you money on tires. Not only that, but having two redundant braking mechanisms is a lot safer and actually required by law in many places.If you insist on going brakeless, you should be able to remove the wheel or tire and rotate it so that the skid patches move to a different point in the rotation.

comment Kickstarter bike too good to be true?
Personally, I wouldn't spend that kind of money without riding the bike first to see how it fit me. Also, all that integrated hidden cabling sounds good from an aerodynamic point of view, but seems like it would be a bugged to maintain. Also, I really don't see the pout of an integrated bike computer, especially with so much changing with those in recent years. Also I would question how one would resolve any warranty issues with a bike bought from a company that doesn't really have much of a history.

comment Fixie vs Road Bike - the right fixie bike for bunch rides
Fixes can be good if you get the right gearing on them and there aren't a lot of hills. As soon as you hit a decently long reasonably steep incline, the people on fixes are going to have trouble keeping up.

comment Selecting a GPS device
@Vorac, your bio says you are in Bulgaria, and I found a link to where you can buy the Bulgarian Topographic Map. Looks like they have maps for most countries, some paid, some free, if you go to the maps section in the link from my previous post.

comment Selecting a GPS device
@Vorac I don't have the topographic maps so I really can't say for certain. You can load your own maps on if you want. There's a site where you can download the OpenStreetMap files for Garmin. That probably won't have topographic or wilderness data, but it was very useful to me. This page says it has European map included, but it's the Irish version of the site. Perhaps it depends where you buy it. Hopefully you can purchase maps for whichever place you wish to visit.

comment Training for long distance rides (> 200km)
@Roka - It seems to me that Zwift does a pretty good job of matching actual ability with the speed in the virtual world. My FTP is only at around 160W-170W and in the game I get up to around 30-35 on the flat sections, which seems to be pretty much what my speed would be in real life. I have a Cyclops Fluid2 with no power meter, so it's obviously just estimating. My best 30 second sprint is at 357 watts which gives me a speed of 44 km/h. If my numbers compare with yours, then you are a much stronger rider than I am.

comment Training for long distance rides (> 200km)
@Roka You might not be able to compare them 1 to 1, but a trainer can help you get some interesting numbers about your FTP (sustainable power output) as well as what your heart rate zones are. To complete a 200 km ride you're definitely going to have to be keeping track of how much energy you are using to make sure you don't run out half way through. You definitely need some real miles on a real bike, but since it seems this isn't available from the OP, it would be a good start to figure out their physical capabilities.

comment Training for long distance rides (> 200km)
Do you have any idea how much wattage you're producing on the trainer? I only ask because a 1.5 hour session on the trainer only ends up being around the equivalent of 50 km for me, and that's at reasonably high intensity. 200 km will probably be an 8 hour ride even for somebody who's done similar distances before. Unless you train for quite a while, you probably won't get under 7 hours on such a long ride.

comment Can a saddle clamp be upside down on a children's bike?
Generally if the frame is so big that you have to slam the seat all the way down, then the frame is too big for you. On older bikes the seat is usually much closer to the frame, but you shouldn't really need to put it down so close to the frame. If you can't stand over the top tube, flat footed, then it's probably too big.

comment I just bought a frame off this kid in my neighborhood but don't know who makes it?
this one looks pretty similar
