comment Help for a 169 mile bike ride
Mississippi is not the Great American Desert. Towns are 10 miles apart or closer, a farmhouse is always within sight. And they are, for the most part, friendly, courteous people who will gladly help you out if you should have such an incredibly unusual experience as shredding a tire. (A broken spoke is a far more likely problem.)

comment new chain skipping
As suggested below, the new chain should have the same number of links as the old one, not be the same length. After all, you are replacing it because it "stretched". But if you run with a "stretched" chain for too long the cogs wear prematurely. A good bike shop will be able to tell you (with a measuring tool) if the cogs are worn too far, or you can use the "lift test": Lift the chain off the cog. If you can lift it more than halfway off the teeth then the cog is too worn.

comment Can I combine different wheel sizes in one mtb?
Terry was making women's bikes with a smaller front wheel in the 70s.

"Boiled eggs" isn't really "carbs".

comment 1996 Mongoose size 19" Crossway 650 replacement size inner tube
I'm guessing the 19" value is printed on the frame somewhere, not on the tire or wheel. Look VERY CAREFULLY on the side of the tire for measurements -- You will see something like 24x1-3/4 or 24x1.75, and usually just before that a cryptic number like 45-507. Find the numbers, write them down, then report back, (Or refer to Sheldon, the god of bicycle technical info.)

comment How do internal hubs work
Hard to answer as there are a half-dozen different schemes. However, I'm sure there are a few "exploded views" on the web somewhere.

comment Inner elbow/bicep tendon pain from drop bars?
How long has this been going on? Any time you change your activity pattern it takes a week or two for your body to adjust. But you should ease off a little. And the sort of pain you describe could be due to carpal tunnel syndrome or due to MADD or McArdle's syndrome -- "minor" genetic disorders that pop up when you overwork muscles.

comment Bike pump: what is this lump?
It's fairly passive. It just a holding tank that absorbs the excess air when you press down hard and fast, then releases it more slowly.

comment Steel vs Aluminum Spokes and Rims
I can't imagine aluminum spokes on any bike -- they'd fail in about 10 minutes. What you want is stainless steel spokes, but it's not that easy to tell stainless from regular steel. (Stainless steel is less attracted to a magnet than regular steel, but it may be hard to judge.) A rim you can pretty much tell by sight, or use a refrigerator magnet to detect steel vs aluminum.

comment Bike pump: what is this lump?
It would appear to be a pressure reservoir, so that when you push down on the pump and all that air can't immediately flow through the narrow hose and into the tube, some of it is stored in the reservoir to be released more slowly. This would make it easier to pump up a tire, since if the air wasn't stored it would just increase the pressure pressing back on the pump handle.

comment Small puncture not repaired even after three attempts, patch leaks every time
1) When roadside install your new tube and then repair the old one at home. 2) Get most of the air out of the tube -- do not try to patch while inflated. 3) Lightly sandpaper the patch area and well beyond -- you always need to go out farther than you think. 4) After applying the glue DO NOT let it go all the way dry, in spite of what the instructions say -- there should be damp spots still visible. 5) Use the end of some tool (or the corner of the patch box) to press the patch into the tube, rubbing from the center outward. 6) Let the cement set at least 15 minutes before inflating.

comment Why so few mountain bikers with spandex?
@Batman - I think mountain bikers are just as "poncy", only in a different way.

comment Bike Cleaning Help
BTW, keeping a bike clean is NOT necessary. I only wash my bike when I fear the weight of the dirt is slowing me down. (Though you should also wash the bike if you get road salt on it.)

comment Bike Cleaning Help
A rusty chain is a sign that chain has not been properly lubricated. Rust on other parts is generally due to storage in damp conditions (and rust on crank and wheels suggests the bike is not an expensive one, as these components would be made of aluminum on a more expensive bike). You may use soap and water to clean the bike, just be sure to not direct a spray from a hose at any of the bearings or, eg, into the brake levers or shifters, where it would get into the cables. And dry thoroughly afterwards. (And learn how to properly lubricate the chain.)

comment Other than spoke count, is there a strength ratings for wheels?
I've never seen any sort of "rating" for wheel strength. And there are many different factors that go into determining strength, some not obvious. For instance, "butted" spokes are probably more durable than the heavier single-gauge spokes.

comment How come my bike has such a short seat post?
When looking for a longer post, do note that seatpost diameter is highly overstandardized -- ie, there are about 50 different "standard" sizes. So you may need to look around a bit to find a match. It's important to get the right diameter.

comment Tyre pressures and Pumps
Brian, either you're reading the gauge wrong or (quite likely) you don't have the "chuck" properly attached to the valve. Many hand pumps chucks are difficult to attach to the valve properly, especially if the tire is entirely deflated to begin with. You often must press your thumb on the tire behind the valve to force the valve out so the chuck can fit completely onto it.

comment Tyre pressures and Pumps
@scoobydoo - 130 psi would likely be more pressure than the pump can deliver, unless it's specifically designed for high-pressure tires.

comment wide rims/narrow tyres danger?
It would not be advised to put 23mm tires on 22mm rims (assuming that is indeed the inside dimension of the rims, between the inner edges of the two flanges).

comment wide rims/narrow tyres danger?
@Blam - I'm asking what the CURRENT rim width is. Assuming the tires are the ones shipped by the bike manufacturer, they would be "tuned" to the rims (or vice-versa). And, as the OP's update shows, indeed the rims are 22mm.
