comment Why do deraillers require a freewheel?
@WTHarper - Though that latter is a good argument for a spoke guard, even though they are considered very un-cool.

comment Life metrics for v-brake pads (time to replace, time to change)
Note that there are usually different types of pad material available -- some "hard" and requiring more force to use, others "soft" and "grabby". The harder pads generally will wear maybe 30-50% longer (though they will probably cause more rim wear). A good shop will usually have 2-3 different types to choose from, in the popular sizes.

comment Life metrics for v-brake pads (time to replace, time to change)
In answer to your original question, you should replace your brake pads when they're getting close to worn out. This is basically a matter of how much pad material is left -- you need to replace them before the metal holder is in any danger of scraping the rims -- could be months, could be years, depending on your use. (Also, on very lightly used bikes, you need to replace the pads when they get dry and hard -- every 5-10 years or so.)

comment How to check the gear before renting a bike?
@QuestionOverflow - But slippage is often due to a worn chain/sprocket. Place the chain on the large front sprocket and pull out on a link near the front side. The chain should not pull away more than about 2/3rds of the height of a sprocket tooth.

comment How to check the gear before renting a bike?
@QuestionOverflow - Place the chain on the smallest front sprocket and middle rear sprocket. Look at the derailer and chain. The derailer should not be curled up all the way (though close) and the chain should not be slack.

comment When should you replace tires after getting a flat?
There's no need to replace a tire because of a simple puncture that did not damage a significant amount of cord in the tire.

comment Do tires with worn sidewalls need to be replaced?
@GeoɹgǝJɐɹoƨ - Yeah, the old gumwall tires "dry rot" quickly, and are quite sensitive to running underinflated as well.

comment Suspension forks on child/youth bicycle for road ringing good?
It depends on how important it is to the kid. If the kid isn't impressed by it, no.

comment How to prevent the quick-release pin on the Tektro drop brake lever from rattling?
I would think there would be several glue-like compounds you could use -- several that would be more easily reversed than Loctite.

comment How do I secure a new bike outside my apartment?
But folks get berated for not searching for an answer, when in fact the answer is almost impossible to find. The SE search prioritizes the search results all wrong.

@Matt - You are right that the search facility sucks.

comment What happened? tube blew the rim?
Minor note: Probably the stress of levering the tire off/onto the rim caused a crack that precipitated the failure in this rim that was apparently already weakened due to wear. The rim would have failed eventually -- the tire change made it happen when it did.

I doubt if it would work very well.

comment quads feel over used while in an aero position
It's normal, when you change the muscles you use or how far you extend them, to experience discomfort for a period of time (from a few days to a few weeks, depending on various factors). An aero position stresses a different set of muscles from riding on the drops.

comment What happened? tube blew the rim?
I am told you can get a rim sidewall failure if the rim gets worn down too far by the bakes. Can't tell from the pics whether that might be the problem. (The confusing thing about the picture is that the strip appears to be mostly black. But that could just be the way the light reflects.)

comment What happened? tube blew the rim?
Unusual rim. Is that solid metal or part plastic or what? Anyway, the rim failure was what precipitated the tire failure, presumably.

comment What happened? tube blew the rim?
I like to inflate the tire a bit, then let it down nearly flat and take it and roll it along the ground a few revs while pressing down a bit, to kind of center and seat the tire bead.

What is that black strip hanging down? Is that the tire's bead?
