comment Rear derailleur hits spokes when switching to largest sprocket
Yeah, any time something tangles with the derailer, especially if it's enough force to damage the derailer, there's danger than the derailer hanger will be bent.

comment Why don't brakes come with 'Safety Levers' any more?
And just ask Garrison Keillor about the hazards of a high center of gravity.

comment exploding inner tubes
Also, it can be a simple mismatch between tire and rim. These are weird tires, and may not be properly matched to the rims.

comment exploding inner tubes
@velo-oldster - Yes, the air expands evenly, but the metal and rubber don't. The tire is creeping off the rim.

comment exploding inner tubes
Where, precisely, was this "gash"? On the inner diameter, the side, or the outer diameter?

comment exploding inner tubes
But place a wheel in the sun so that only one side of the tire is getting sun and there will be differential expansion. This will exacerbate any tendency of the tire to slip off the rim.

It wouldn't produce that large of a rip.

But a tube won't fail from overpressure unless the tire fails too. If the tire is not being (apparently) damaged then it must be slipping off the rim.

comment exploding inner tubes
I recall this happening to several guys on a ride 20-odd years ago. They were riding old (new then) racers with full pannier loads, meaning the wheels were way overloaded. Laid the bikes down in the parking lot on a sunny day and within 10 minutes -- "BOOM". I saw one of them go: The tire bead slipped from the rim and the tube was bulging a couple of inches before it popped. Dollars to donuts your tires are slipping off the rims.

comment Why is cycling on a road so much faster than cycling on a cycle path?
It's rare that a cycle path is as straight and level as a motorway, and the surface is often rougher as well. (Among other things, the traffic on motorways smooths off the rough surface to a degree.)

comment DIY colouring components
Generally the colored parts are aluminum, and the color is applied in the anodizing process. I suspect that attempting this at home (in addition to involving some modestly caustic materials) would risk fouling the threads of the components. You might try "gun black" on some steel components, and there are various metal dyes.

comment Squeaky rear wheel when rotating
Then look for something (eg, string or a bit of vine) caught between the dust cover on this end and the hub.

comment Disabling back-pedal brake
@NeilFein - I'm just saying that I can't recall the brakes in an old-style Bendix hub ever wearing out, or even in a New Departure, and they were subjected to enormous abuse when I was a kid. And they didn't need adjustment at all -- nothing to adjust.

That's something rubbing against the tire.

comment Why is the front brake lever on the right if you 'drive' on the left and vice-versa?
@armb - I mean the rear cable would have to somehow transition from the left side to the right side. I suppose this could be accomplished along the downtube, but then the cable would conflict with the front cable coming down on the right, and the cable would rub against the downtube.

comment In which orientation should a front wheel be installed?
I've never seen a hub where the cones were directional -- this is not a feature of standard hubs. But I suppose perhaps your hub is unusual in this regard.
