comment Why are my wrists the first part of my body to start aching during a long ride?
I had a (flat bar) bike where trying padded grips and gloves, and adding bar ends for more hand positions, didn't help, but swapping the stem to a shorter one did. But without knowing more about your riding position, I have no idea if that's the same problem you have. It wasn't obvious to me that I had too much weight on my hands with the original set-up, but apparently I did. If you have or can borrow an adjustable stem, see if different positions help.

comment What is mysteriously slicing the inside of my tubes?
Unless you take the tyre off when fitting a new tube and put it on in a random position, but patch without taking the tyre all the way off, so it stays in the same position once you've changed the tube. In which case Daniel is almost certainly right. If you still can't find anything, swap the front and back tyres. If the problem moves wheel with the tyre, change the tyre even if you still can't find a loose wire.

comment What is mysteriously slicing the inside of my tubes?
Are you installing the tyre in the same place every time (e.g. label by valve)? Though I don't see how that would explain "different places with each new tube. But it doesn't move around once the new tube is put in".

comment Why don't cyclists wear all-encompassing motorcycle-style helmets?
Pedestrians can and do lose front teeth when they trip over too. This is why full face helmets make as much sense for walking as they do for cycling. It also solves the "where do I leave the helmet when I lock the bike up" problem.

comment Are older road bike parts compatible with newer standards? How do older and newer bikes match up performance wise?
My bike is early 90's, 126mm hub (7 speed), freehub, 700c wheels. I bought it new though :-) I've recently respaced the frame to 130mm and fitted a new groupset (with brakes swapped for long reach ones to fit). The wheels weren't the originals even before that, but were the same size. Buying a new bike might have been more rational than the upgrade though.

comment Adjusting brake rub on a mini-v brake (Giant Propel)
It's not labelled on the photo of the parts, but it's shown in the drawing for "5. Center the brake arms by turning the spring tension screw (align to seat stay)" on page 4.

comment In practical terms, how often do you have to adjust the belt tension of a belt drive bicycle?
Timing chains in car engines also last many thousands of miles without replacement or adjustment, but it would be wrong to conclude that therefore bike chains can do the same.

comment How to remove a stuck seatpost?
Am I sure? No. The rust in the cable guide could be entirely from the cable, the rust inside the hole for the missing seat bolt could be from the missing bolt. But cheap steel frames can be fairly thick. The original poster should definitely check carefully before resorting to extreme measures.

comment Is it possible to remove wheel without loosening the (V) brakes
If you could add a photo (or photos, with brakes both applied and not applied) of your brakes, it might help.

comment Is it possible to remove wheel without loosening the (V) brakes
Loosen the locknut on the barrel adjuster, screw it into the lever to create some slack, assuming it isn't all the way in already, unhook noodle. When done, screw the adjuster out to take up slack, then do up the locknut again. Assuming you have similar adjusters to most. But that isn't normally necessary, it's a workaround for not being able to use the quick release, so look into changing the noodle and/or which washers/pads you are using too.

comment How to remove cantilever brake arm?
Depends on the frame. Weld on or braze on bosses are common, e.g. framebuilding.com/Bosses.htm

comment How to work around a high seatpost?
If it's only very slightly too high, then it might be possible to swap the saddle for one that is slightly lower when mounted on the same post. If it's an old style clamp mount (sheldonbrown.com/harris/images/ST4200.jpg), you might be able to mount a saddle (not necessarily the current one) with the rails clamped at the bottom rather than the top. But getting it unstuck is the real answer.

You might be able to slacken the cable slightly using the barrel adjusters on your levers. Remember to re-adjust them so that you can apply the brakes properly when you have put the noodle holder back at the end.

comment How to remove a stuck seatpost?
Looks like rust on a steel frame, but aluminium oxide on the seatpost. Which means that worst case, Sheldon's option 14, caustic soda, will work. I've done it.

comment Is threadless a noticeable difference from threaded headset setups?
If a quill stem isn't overtightened, it will also allow your handlebars to rotate relative to your stem in a crash situation. I suspect the difference is less quill vs threadless and more steel vs carbon. sheldonbrown.com/handsup.html "If a bicycle has an older quill stem with a conical expander, it is normal to be able to turn the handlebars with moderately strong hand force, when standing in front of the bicycle and holding the front wheel between the legs. Turning the handlebars will be more difficult if the stem has a wedge."

comment Can I use a 9-speed shifter with a 8-speed cassette?
(I've been using the "Campag old 9 Hubbub S7" setup for some years; it's not just for makeshift repairs. But I now have a shiny new Tiagra groupset for that bike.)

comment Can I use a 9-speed shifter with a 8-speed cassette?
ctc.org.uk/cyclists-library/components/transmission-gears/… has a photo showing how to reroute the cable for a 9 speed cassette to work with an 8 speed shifter. My guess is that doing something more like the "New Dura-Ace convert to old style" diagram on that page could do the reverse. I agree a photo of his setup would help.
