comment What is a nipple driver and would I use one to replace a broken spoke?
Note that you can use a standard screwdriver for this duty, but it will be a hair more difficult to keep it centered on the nipple. Or you can grind down the tip of a regular screwdriver to have a little center pin as seen in the second photo above.

comment Rolling backwards while pedaling forward on a Freecoaster
(Just watched the video, and the mechanism is EXACTLY like a coaster brake, only without the brake.)

comment Rolling backwards while pedaling forward on a Freecoaster
Had never heard of the "free coaster" as you describe it. Sounds essentially like the "coaster brake" without a brake, though -- uses the same basic mechanism. Based on your description, however, pedaling forward while rolling backwards you would NOT have to keep pedaling to keep the pedals engaged, but simply pedal forward briefly to engage the clutch. Once the clutch was engaged the relative "attempted" motion between the two pieces would keep it engaged.

comment What could cause a tyre to deform in this way?
There is also the odd chance that this is, eg, a 26 inch tire but there is a 700c tube inside and the tube has gotten folded up on itself. If the above deflate/inflate fails to fix it, deflate again and remove the tube, checking if it's the right size and does not show signs that a part of it has been folded up.

comment What could cause a tyre to deform in this way?
Assuming the rim is straight, either the tire is "bruised" (the cord inside is broken) or it has somehow managed to slip sideways on the rim. Completely deflate the tire, try to "re-center" it, then re-inflate, tugging as needed to keep the tire straight as you inflate. If it goes back on straight it was probably just an unlucky bounce off a curb. If it won't straighten up the tire is likely damaged.

comment What size cone wrench am I likely to need for a Trek 1.5 2011 Compact rear hub?
Just buy a set -- not much more than a single wrench, and the front will probably use a different size from the rear anyway.

comment Replacing rear hub, beginners advice required
First see if you can rebuild the hub and re-true the wheel. If the bearing races aren't damaged then new balls is all you need -- available from any bike shop. If the hub can be rebuilt, then no problem. If not, buy a new wheel. To rebuild you'd need the new hub and new spokes and a LOT of time. Maybe worthwhile as an "experience", but not in terms of dollars and cents (especially if you have to hire out the rebuild).

Don't the rollers make it hard to keep your feet on the pedals?

comment When to tune/replace brake cables for optimum tension
It does appear that somehow your spring tension is not even. The front brakes were not centered well before you made the adjustments, and the back ones do not center well after adjustment. (At least from what someone can judge from the photos.) But adjusting brake springs is a black art.

I've seen it done.

comment When to tune/replace brake cables for optimum tension
Looks to me like you've got your brake cable routed wrong, or possibly you've managed to twist the handlebar a full 360 degrees.

Yeah, I'll see if I can get a picture in the next few days.

It sounds like the rear derailer is simply misadjusted.

comment Most effective upgrades on Road bike
So long as the bike fits you, nothing you can do will make THAT much difference. Just enjoy the bike, and only replace stuff you discover doesn't suit you.

comment triathlon handlebars for ultegra di2
I don't see how (i) is "nasty work". It should be quite simple and straight-forward. I've never looked closely as an electronic shifter setup, but it may even be possible to do it without cutting wires (by putting multiple wires under one screw terminal, eg), or someone may sell a harness adapter to do it.

comment Spoke tension - is a left tilt ok to prevent explosion?
Breaking at the nipple end is often a combo of poor quality spokes and an oblique angle of the spoke to the rim, such that the spoke is forced to flex quite a bit on entry to the nipple. The oblique angle, in turn, can be due to a combo of an oversized hub and/or a relatively small wheel.

comment Spoke tension - is a left tilt ok to prevent explosion?
What do you mean by "exploding inside the nipples"??? If you mean that the nipples themselves are splitting open then they sound like inferior nipples. As to the longer nipples, nipples come in various lengths -- there's not really any pattern only some lengths work better with certain rims. And having the wheel perfectly centered is only really critical for rim brakes.

In that case it's just another lock nut.

comment Can small pebble inside tire puncture the tube?
There would only be significant friction if the tire is run at low pressure. For tires held at high pressure the tube is generally almost welded to the tire.

Should be no real need to remove the bottom bracket. Remove the chain, maybe, and tape the crank arms horizontally after removing the pedals.
