comment Do softer tires provide better suspension?
And for those who think I do not know of which I speak, I used to test rubbers for the Air Force.

Folks, note that he specifically says that tire pressure is equal when making these comparisons.

comment Chain falling off inner chain ring no matter how L screw is set
I would wonder if the chain has come partly apart. Did you check it to make sure all the links look straight?

comment Chain rings slip when crank is turned
Quite unlikely, but there have occasionally been bikes with an internal gear in the crank. But this would be quite rare, and not found on a "normal" bike. (Far more likely is the swaged crank coming loose.)

comment Does the Brooks Cambium C17 Saddle rub off?
Yes, I've had this with other leather seats and light-colored shorts. This is one reason why cycling shorts are black. Dunno about the Cambium -- perhaps Brooks felt their clientele would not like it unless it rubbed off like leather.

comment When do I need more than one bike? How many bike is enough? How many bikes is too many?
@Blam - You buy bikes, some people make money. Both can find it hard to stop -- they always need a little more.

And don't forget insurance.

comment How to start a grassroots DH race?
I'm guessing the hill owners will want you to buy insurance, to protect them from liability.

(One does need to consider practical matters such as garage space and (cough) money.)

comment When do I need more than one bike? How many bike is enough? How many bikes is too many?
(My bike is a touring bike, which is a decent road bike (I never race) and can handle relatively "tame" trails pretty well. Good for commuting, good for general "tooling around", good for touring. The only time I've ever considered another bike was when I was (briefly) getting into winter biking, and for that I would have wanted bike with studded tires and without fenders. Could have switched the tourer back and fourth, of course, but a second bike would have been much more practical.)

That's like asking if you can have too much money.

No need to replace the brake pads until they've been found to be bad. They will get harder with age, but if they were pretty soft to begin with that's not such a bad thing.

comment I want to weld or braze the pedal to the crank arm, but what metals are they?
Another option is to fill the hole with aluminum weld, then drill and re-tap. Again, for the left side you'd need a left-hand tap.

The other option is to install a Helicoil in the arm. Easier if it's the right side, since left-hand Helicoils are probably hard to find (though bike shops may carry them). (I wouldn't expect epoxy to last more than a few days.)

comment What can be done to fix a hub that has come apart?
@Carel - When I was rehabbing bikes for Christmas Anonymous I saw hubs much worse than that turn out OK.

comment What can be done to fix a hub that has come apart?
The hub needs to be disassembled, cleaned, and reassembled, taking care to get the "cones" holding the balls in to the proper tightness (a little bit of an art, or a lot of trial-and-error), and taking care to get the thin lock nuts just outside the cones tight against the cones. The only "special" tool needed is a thin "cone wrench" of the proper size -- otherwise you just need a few open-end wrenches, solvent to clean things up, and fresh grease. (Though it doesn't hurt to replace the balls while you're at it -- they're cheap.)

comment Carrying Pizza on a Bicycle
Put it on the seat and sit on it? (I would think that a medium sized pizza could be carried on the rear rack, though you'd probably want to add some sort of platform.)

Yeah, the only thing that must be replaced is the tires (assuming no one has replaced them in the past 20 years). And you probably need to oil the chain and squirt some lube on the brake pivots and derailers.

It's old, likely with old-style, non-indexed shifting. Probably built in the 80s. Lightly used (the handlebar tape is clean). The tires will almost certainly need replacing, but otherwise it appears to be in good condition. The narrow tires (looks like 1-1/4 maybe) are not suited for off-road or cobbles. It's a relatively tall bike -- probably best for someone 6 feet or taller.
