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.

comment Are out of date energy gels bad for you?
It's mostly a question of storage. If they've been stored in your car for a year, throw them out. If in your house, at a reasonable temperature, they should be good for at least a year after the expiration date.

comment wide rims/narrow tyres danger?
@Blam - It's 15 to 19 by Sheldon's chart, and I've seen rims out to about 23 used.

comment Can I use a road bike for commuting 11 miles each way without SPANDEX
I rode a 12 miles to work and back for decades before I bought my first Spandex shorts. I commonly rode in cotton T-shirt and lined jogging shorts. The one thing most likely to be an issue (besides staying cool and keeping your pant legs out of the chain) is your underwear -- the wrong underwear can be unbearable.

comment wide rims/narrow tyres danger?
You should, of course, see what your current rim width is. There is a fairly wide variation in rim widths for tires that wide.

comment Shifter cable running beneath the bottom bracket without a sheath
(If the rear derailer is shifting on its own check the frame carefully for cracks.)

comment Shifter cable running beneath the bottom bracket without a sheath
The scheme you describe is quite common, and in fact is preferred over fully sheathed cable because there is less friction. I've never seen the friction blocks fail, other than when they've been physically damaged (which is rare).

comment Can you remove the chain missing link too often?
Invest in a "chain washer". A lot faster/cleaner and virtually no chance of somehow compromising the chain.

comment Vandalized top tube
In Africa they'd bang it out straight, splice a piece of wood to the top tube (possibly with duct tape) and keep riding. But by American/European standards it's a goner -- too apt to fail at other points, even if the top tube is somehow "made whole" again.

comment Cyclocross Bike On the Road
You might look for tires that are relatively smooth down the center, but have a passable off-road tread on the sides. (I would assume that such tires are made.) And, if you can, adjust your tire pressure between the two conditions, raising it to near the sidewall max while on the road.

comment Bike not changing correctly between two gears
@gaoithe - The pantograph automatically compensates for chain stretch. Well before the pantograph runs out of range the chain should be replaced.
