comment What kind of pump do I need for this valve?
And, yes, to prepare the valve for filling you need to unscrew the knurled piece all the way until it stops (don't force) and then give the tip of the valve a little press to free the rubber gasket. When done, retighten the knurled piece, but only just finger tight -- over-tightening will just cause the rubber gasket inside to fail sooner.

On some pumps you unscrew the ring on the chuck, reverse the "innards", and re-install the ring.

comment Are 22mm tires too thin for commuting?
IMO, 22mm is narrower than ideal for commuting -- 27 or so would be a better width. But it depends on your riding style and the course you follow. Also, for commuting you don't want super-thin racing tires, if for no other reason than they will wear through too fast. You do need to run a pressure commensurate with tire width, and again, the narrower tires self-deflate more rapidly than wider ones (though a lot depends on the brand of tube). It's not that 22mm is wrong, it's just not ideal for commuting.

comment What are the benefits of 700c23 tires?
@amcnabb -- Well, I think mine (Performance) are technically rated at 90. My old Schwalbes, though, were rated at 105, IIRC.

I'm done arguing. Believe what you want, you're wrong.

comment Would a military helmet make a safe alternative to a bicycle helmet?
Actually, there are many common design points between the modern military helmet and the bike helmet. The main difference is that the military helmet has the additional duty to deflect shrapnel, et all. But it does this by spreading out the impact, in time and in space, using the same crushable liner technique as used in a bike helmet.

comment When do bearings need to be replaced?
Note that bearings in need of replacing will almost always be loose and allow the wheel/shaft/whatever to slide side-to-side. (And such looseness does not indicate that the bearings need to be replaced but they should be checked by a skilled mechanic.) Normally, on a bike not left exposed to the elements 24/7, good-quality bike bearings should last 25-50,000 miles or so.

comment Would a military helmet make a safe alternative to a bicycle helmet?
Actually, a military combat helmet would likely provide substantial protection, maybe at a level 25% as good as a certified bike helmet. If it were that or nothing I'd wear it (assuming the visibility and ventilation issued did not prevent it). But a "real" bike helmet is still greatly to be preferred. (BTW, the need to frequently replace your helmet is greatly exaggerated. Simply commuting, your head should almost never impact the ground or some other immobile object at high speed. (Off-roading or stunt riding would be a different matter.)

comment Jammed Giant brand U-Lock. Unable to insert key
If you have a Harbor Freight near you you can get an angle grinder for $15. (Other places like Northern Tool and even Home Detail will likely have similar units priced only a little higher.) With a metal-cutting blade this will make short work of the lock. (Be sure to wear good safety glasses and cover your arms when working with any metal-cutting saw.)

I don't think the "removed the key too hastily" idea has much merit.

comment Jammed Giant brand U-Lock. Unable to insert key
+1 Yep, simply wiggling a lot is often the ticket, though jm2's suggestion of some dirt in the lock should be considered. It can't hurt, with the classic barrel key design, to dig through the circular channel with a pin or paper clip. With a conventional bladed key about all you can do it position the lock slot-down and whack it good a few dozen times.

@ThaRiddla -- The problem is that graphite powder won't *un-bum" a stuck lock, whereas a solvent like WD-40 likely will. Or better, you could get a purpose-made lock spray. After it's free it should be well-lubed with pure Teflon spray -- graphite is only about 1/10th as effective as Teflon.

comment Can I zero the gauge on my floor pump
Hard to say. Some gauges are adjusted by twisting the gauge body, some are supposedly "factory sealed". But I'd bet you have the former.
