Old, tired, crazy.

comment Why does coaster brake hub growl when coasting but not when braking or pedaling?
There are several different schemes, but basically the coaster brake has two threaded shafts, one that tightens when you pedal, pulling together a clutch that drives the wheel, and one that tightens (as the other loosens) when you back-pedal, to pull together the brake. When you're coasting both the clutch and the brake are "open", but one or the other may be close to touching and hence make some noise. Or, if things are loose (which they should not be) it could simply be rattling inside. You should take it back to where you got the bearings replaced and have them fix it so it's not loose.

comment How do Mini V-brakes compare to cantilever brakes for Cyclocross bikes?
Just a bit of trivia: V brakes were invented by Shimano to allow suspension forks to be built without a "bridge" to carry the central brake pivot (or cable anchor/bridle, in the case of cantis). It is only good marketing that got them onto virtually every bike made, suspension or not.

comment What are the downsides of a twisted wheel?
It would be very unusual for such a problem to require replacing the wheel. How much it will cost to have a bike shop fix it depends on whether they just "tweak" the wheel (possibly free) or instead insist on giving it a full "tune up" (likely tens of dollars/Euros).

comment Chain Splitter vs. Chain Tool vs. Chain Breaker
Yeah, that's one. There are other designs.

comment Chain Splitter vs. Chain Tool vs. Chain Breaker
There is a "chain breaker" that is like a pair of pliers, vs using the threaded shaft for forcing the pin out. And you need some sort of "chain breaker" even if you use Power Links, et al, since you still have to cut the new chain to length.

comment Can disc brakes be considered safe for road group rides?
Any cyclist leading a line needs to be aware of those behind him when braking, and modulate his braking as conditions warrant.

comment Can I upgrade V-brake to disk brake for Cannondale Quick Cx 5
@Kibbee - But to supply a frame with disk lugs would mean the manufacturer would have to install a different, heavier, less flexible fork.

comment Can I upgrade V-brake to disk brake for Cannondale Quick Cx 5
If the frame does not have lugs on the fork and rear stays to attach the calipers then it's highly impractical to change. Otherwise it's simply impractical.

comment Chain rings slip when crank is turned
As has been pointed out in a duplicate thread, there once was a Shimano "Front Freewheel System" which placed a freewheel mechanism with the front sprockets. See this skeleton Wikipedia article for some basic info. Note that the article claims that some specialized mountain bikes still use the scheme, even though it would have disappeared from regular bikes by 1990 or earlier.

comment Pedals turn but front sprocket does not
Yep, see en.wikipedia.org/wiki/Front_freewheel . There are even some pictures. The article says "Non-proprietary front freewheels can currently be found on bikes used for bike trials riding." Otherwise the bike would probably have to date from before 1990 or so.

comment Rat a Tat noises coming from my bottom bracket area. Please help!
Yeah, might as well try different pedals. I've definitely had trouble with pedals going bad roughly the way you describe. Beyond that I'd check the chainline and make sure it's not the chain trying to crawl off the sprocket.

comment What is this apparatus for?
Yeah, I couldn't find it either. But Google images for "drying box" and you will see a number of roughly similar devices.

comment What is this apparatus for?
Best guess is that it is a (greatly overpriced) shoe dryer.

comment cantilever brakes have 1mm play in then is this normal?
This is not terribly uncommon, nor is it usually a problem. If it bugs you, you can find "shim washers" at a hardware store to remove the play. The only thing to check for is to make sure you don't have removable studs that have come partly unscrewed.

comment Sticky / broken floor pump head?
Yeah, I'd disassemble, clean, and lubricate with some sort of silicone lubricant. If that doesn't do it, replace the head and/or head/hose assembly -- replacement parts are fairly readily available online (and you can get one that is totally "agnostic").

comment Chain Slipping?
This can happen when you get a washer on the wrong side of the "dropout" slot or simply do not get the wheel properly seated in the slots.

comment Do softer tires provide better suspension?
@user713303 - My experience has been that a good quality Kevlar layer provides excellent protection against punctures, with only a slight impact on rolling resistance (and weight). Perhaps the thicker tires provide more, but (for me) the difference between a flat every 4 years or every 6 is not worth the extra resistance/weight.

comment Cycling position for commuting
Yep, with most drop bars it's actually easiest to operate the brakes when you're "on the hoods", and that's where you'd have your hands most of the time anyway.

comment Cycling position for commuting
For 6 miles -- whatever's most comfortable for you, and suits your "style". For longer distances you'd be more concerned about posture.

And for those who think I do not know of which I speak, I used to test rubbers for the Air Force.
