comment Retrieving Loose Nipple from Inside Rim
I think you are unfamiliar with the construction of the typical double-walled rim.

comment Why don't road bikes use v-brakes?
Of course, there is no inherent difference between cantis and V-brakes -- they work exactly the same. It's just that Shimano released V-brakes with a mechanical advantage setup that has less modulation (and hence more "grab"), presumably to sell to off-roaders. It would be nice if they produced levers with different geometry, to reduce grab for on-road (who needs to skid a road bike?) but they don't.

comment Should disc brake rotors be removed when packing bike for travel?
More important than removing the rotors is to place a dummy axle between the dropouts (assuming the wheel is removed). Also, unbolt the rear derailer and tape it loosely to the chain stay.

comment Rear wheel rubs frame/cage while pedaling standing up
Note that tire width does not take into account however much the tread may stick out. If you have oversized tires with heavily lugged treads then that's likely your problem.

Oh, I see. The wheel is likely not mounted straight, or you could have loose wheel bearings. Or the tires are simply too wide for the bike.

Because you said so. ;)

comment How is Sir Bradley Wiggins 3D printing his titanium handlebars?
It's a process which involves the application of a lot of money.

comment Alleviating pressure from coccyx with padded shorts
If you can't handle 11 miles without trouble then you're probably not sitting properly. Especially with that narrow saddle you need to make sure your sit bones are carrying the pressure.

There would be a problem if he wanted to replace his front brifter with a simple brake lever, given he has hydraulic brakes.

Perhaps you need to adjust the low limit on the rear derailer.

comment Does cycling make one's knees stronger?
It depends on what you're doing and what problems your knees may have. You can wreck your knees with the seat too low or running in too difficult a gear. You can also aggravate various conditions -- congenital or due to prior injury -- by overdoing it with the biking. Since you're having the pain you'd be well advised to consult a knee doc.

Easy -- just stop using the front shifter.

comment Finding the right length of chain lock for my road bike
To measure what length you need for a chain or cable lock, get yourself a piece of string or cord and try it, "locking" the bike to several different objects. And consider getting a U lock, then use a cable to secure the other wheel.

comment What is the best way to approach train tracks?
Approach as squarely as possible and "levitate" over the tracks, raising your bum off the seat and keeping your arms and legs bent. If the track is slanted such that the right side (left in England) is nearer than the left, swing out into traffic (carefully), "claiming" the lane, and then approach the track squarely. If the left side is nearer, it may be more expedient to dismount and walk across. Also, if the tracks are wet take extra care (or, as one wag put it, crawl across, dragging your bike behind you).

comment Why aren't hub/drum/roller brakes suitable for touring?
It is a bit curious, since 30-40 years ago tandems and heavy touring bikes were often equipped with drum brakes. My guess is that rim brakes have gotten better, and disk brakes have taken over the "heavy duty" segment of the market.

@WillVousden - What?? It's possible to buy something other than Shimano??

comment brief pain and swelling in hips during intense movement
The problem is that you may have a "zebra", and, curiously, zebras are often invisible to doctors.

comment Converting 80s bike to indexed shifters
At the very least you need a new rear sprocket cluster. The secret to indexed shifting is the profile of the sprockets, with "ramps" on the sides of them to lift the chain up to the next larger cog. The pins of the chain engage in these ramps, and that's what makes the magic. And, of course, the spacing of the cogs, the geometry of the derailer, and the design of the shifter must all match so that a click on the shifter moves the chain exactly one cog's distance.

comment One crank arm won't come off
If the first one came off without a puller it was probably too loose.

comment brief pain and swelling in hips during intense movement
It definitely sounds like you have a medical problem. One possibility is a metabolic disorder such as McArdle's disease (for which you'd need to see a neurologist, oddly). Another is a circulation problem, or a problem with the lymphatic system. Your weight is a bit much for your height, but not enough to cause such problems (other than the obvious one of having the seat support you properly).
