comment Can I use WD-40 on my bike?
There's nothing particularly wrong with it, but it's not generally a good lubricant. I use it sometimes to clean derailers, but it's a lousy chain lube.

comment How many people use their mountain bikes for road riding?
@Kibbee - Department stores sell bikes for sex (though kiddie style sex, for those who don't know what sex is). In that context how well a bike rides or how appropriate it is for the rider in not important -- it's how it looks on the showroom floor. (And this is even true to an extent in "legitimate" bike shops, where bikes are set up with the handlebars too low, et al, because that looks "meaner".)

Oh, Lord!! Don't ever use a mountain bike for road biking. It will lead to the end of the universe as we know it! (IOW, a bike is a bike. What's the issue?)

Sounds like your cogs are worn out.

comment My chain appears to be squeaking when I ride it forward but not backwards
At 3000 miles the chain is probably due for replacement.

comment Will an 1/8' chain and cogs wear slower than 3/32' chain and cogs for single speed / fixed gear setup?
I doubt that there's much difference in chain or cog life. And a 1/8 chain on 3/32 cogs might actually wear the cogs faster. I think the main advantage of a fully 1/8" driveline would be that the chain would be less apt to jam (but that's a very, very rare event anyway).

comment Would you do a 15mile + commute on an electric bicycle? Which one?
An electric bike will help you get up a hill you might otherwise have trouble with. And the extra weight isn't that much (when you're not on a hill).

comment Would you do a 15mile + commute on an electric bicycle? Which one?
1) Yes, if I had one. 2) Probably I'd commute to where I wanted to go.

And does it squeak at any particular point in the pedal rotation?

How many miles (about) on the chain and sprockets? Can you get any hint as to where the squeak is coming from?

comment Checking fixie for damage
There's a vague possibility that you stripped the lockring. And more than a vague possibility that you've bent the cog or ring. Also, the wheel may have been knocked out of true.

comment Are deep rims more durable for a heavy rider?
Yep, a spoke count of at least 32, and preferably 36. (40 would probably be overkill.) Generally this will be a 3-cross lacing pattern. Some people like to have radially laced fronts, but, while the jury is out on whether this is technically as strong as a crossed pattern, IMO radial will not provide as much "spring" and will be more apt to lead to broken spokes, sprung wheels, etc.

comment Why do current, entry-level shimano rear derailers have large-diameter pulleys?
Actually, most of the chain-related friction would be in the chain wrapping and unwrapping the front and rear cogs while under tension. But the chain is under very little tension while going through the derailer, and hence friction is low.

Derailers last pretty much forever anyway -- no real need to improve their life expectancy. The larger jockey would likely increase chain capacity slightly, with no increase in cage length.

comment Why do current, entry-level shimano rear derailers have large-diameter pulleys?
Yeah, I suspect that the larger pulleys would have lower friction and be more efficient, aside from the negligible weight difference.

It almost certainly has to do with cheaply filling some niche, probably on low-end mountain bikes. One possibility is that the larger jockey wheels make shifting more reliable with some system, possibly their electric shift scheme.

comment What is the stem/seatpost thing on the Bicymple?
I think it's known as an "abomination".

comment Could I switch tires on an MTB to tires with less friction if I mostly use the MTB in a city environment?
As to whether you should get another bike, there are some folks who have several, and use them all for different purposes, and some who get by just fine with only one bike in multiple environments.
