I'm a commuter mostly, about 20km a day, for the last 15 years, in all weather. Sydney weather is not too harsh though.

I've done a little cycle touring. Most recently circumnavigating Samoa in early 2011.

I did a few weeks as a bicycle courier back in the 90s whilst on holidays from my permanent job.

comment Can I measure my bottom bracket size without removing the cranks?
When aiming for ideal chain line and deciding on BB length, don't forget to keep in mind that you can't go too narrow at the front. Depending on your frame and chainring size you need to consider whether the chainrings and crank arms will clear the frame.

comment When should I not use my front brake?
@ChrisW Motorcycles are similar to bicycles in braking dynamics. A motorcycle safety course will teach you that the front brake is the most effective brake to stop you in a straight line but the most dangerous brake whilst cornering. A skilled rider may be able to control rear wheel slide in corners or on loose surfaces but once the front starts to slide no amount of skill will save you. Controlling speed before corners is the most critical factor though. It can save your life. In Australia around 50% of motorcycle fatalities are simply due to going too fast into a corner.

comment When should I not use my front brake?
From motorcycle to bicycle and even to car, braking through corners is generally not a good idea. Braking should be done before cornering. A motorcycle safety course will teach you not to front brake in corners and to brake before corners (around 50% of motorcyle fatalities in Australia are simply going too fast in corners). I'd be concerned for your safety and others with the advice to use the front brake in corners. A rider may be able to control a rear wheel skid (and back off the brake), but no amount of skill will save you if your front wheel loses traction whilst cornering.

comment What happened? tube blew the rim?
You were lucky this didn't happen whilst riding at speed! A useful reminder for us all to check rim wear when using rim brakes, or to check for cracks in the rim and replace immediately.

comment English vs Italian bottom bracket - chainline considerations
@fideli I removed the discussion about longer tapers, since you are right, the JIS taper should be the same length.

comment Are there any 'anti-fly' masks on the market?
@KenHiatt You should make that an answer :-) Although, I work next to a dietitian and she says flies have almost no body mass and you're going to pass them out pretty quick and so you won't be getting much protein from them. Might have to up the estimate on the number of flies per energy bar.

comment How do I cut hydraulic brake hose without expensive tools?
I ended up finding a cheap $20 Jagwire cutter online in Australia. I have to say it was not worth the $20. Two things make it worthless. 1. The blade is so slim it flexes. Even though the blade comes down on the hose, it still flexes and doesn't cut straight. 2. The section to hold the hose perpendicular to the blade is too short, so it is not great for holding it perpendicular.

comment How to measure the correct belt drive tension?
@DanielRHicks I doubt the belt stretched, unless it is damaged. That is one of the major reasons to go with a belt. No stretch. Sounds like the iPhone App is inconsistent though, also judging by zenbike's comment to my answer.

comment How to measure the correct belt drive tension?
@Moab I'm curious as to whether you have a belt drive bicycle and use this method on your bicycle.

comment How to measure the correct belt drive tension?
@zenbike Thanks for being specific. Hopefully what has become clear from the OP and answers is that "press hard" and "1/4 to 1/2" movement" is far too vague for belt drive bicycles and that the correct belt tension is critical to safety and proper function, and the margin or tolerance of correct tension is small. Thus belt drives bicycles are nothing like chains, as a chain can tolerate quite a difference in tension. I think the use of torque wrenches is a good parallel. If you have vast amounts of experience, you may not need them. Even then, to assure customers, shops will.

@zenbike Thanks for the real world experience. I don't have a belt drive so haven't used the app. I posted because I read about it when considering a belt drive.

comment How do I cut hydraulic brake hose without expensive tools?
@heltonbiker I'm not so sure. I tried using a couple of methods. One was to use the blocks that come with Shimano cables to try and guide the cut. That didn't give a perfect cut. I then got a cheap Jagwire cutter for $20 (I found one in Oz). That wasn't great either. The blade flexes and didn't cut perfectly perpendicular. I inserted the insert anyway and if it is not perfectly straight you'll get leaks between hose and insert. That is what happened. So I'll do it again but using a small mitre box and knife.

comment Can a worn drive-train be upgraded incrementally or should it be all at once?
@DanielRHicks You are right, but I was mostly just answering "I'm a little bit leery about throwing good money after bad into a used bike" (which other answers hadn't), by pointing out there could be many more maintenance costs down the track with the old bike. Hence the recommendation for someone to look at it and assess future costs.

comment Can a worn drive-train be upgraded incrementally or should it be all at once?
@LarryOBrien Yep, if you're not sure if you'll stick to it then maybe spend a little to get going, and 30 miles (50km), is around about where you can get away with a few worn parts. Unless you're really keen on tinkering though, even if you stick to 30 miles, you'll probably find yourself weighing up options of new vs repairing old. Although that depends highly on how serviceable the old one is. Only someone who has seen your bike can have an idea of that.

I'm in Australia and none of the hydraulic cable cutters on Amazon ship to Australia, and I can't find these at the LBS.

This is probably what I'll do, but I'd like a bit more info on how I can get the cut perfectly square.

comment Did any manufacturer ever try using more, but lighter spokes to minimize weight?
@user973810 You need two holes in the rim for each spoke (through the cross section of rim). Surely that will offset the weight of the spoke and nipple a bit (not sure how much).

comment Safest way to slow down a bike quickly if both sets of brakes fail
Takes me back to riding a BMX in the 80s. The Comp III was the tire to have then. I don't remember the pain, but hey, we was young and that was a long time ago.

comment How long is it safe to store new tires before they degrade in quality?
Did you ask the manufacturer? Maybe they can give you info since they have to store tires themselves.

comment What type of tires can prevent goatheads?
Schwalbe Durano Plus is probably the most puncture resistant road bike tire.
