comment Can Park Tool CG-2.2 kit work with the bike upside down?
I've never tried it, and there would be some problems. You need to have the tool on the slack side of the chain as it's pulled backwards off the jockeys and onto the front ring. Probably, as Moz suggests, you'd end up with the handle (if you use it) on the frame side of the chain.

@mattnz - Particularly observe the warning about losing fingers.

comment 2 speed quad sprocket bike… do these exist? If not, why not?
As a practical matter you get most of the same advantages from a bike with a regular multi-speed hub, so there's no (selling) point in making one. But you can certainly make one for yourself if you wish.

comment durablity and brand?
It's a full-suspension bike, and such bikes are purported to be designed for fairly rugged off-road use. However, some Chinese makers produce "wannabe" bikes that look tough but are barely suited for city streets, so it's hard to say.

comment Chain lube that won't repaint my legs?
Nothing will be perfect. Chain wax is probably the least likely to rub off, but when the chain gets dirty the dirt rubs off regardless.

Get some gaiters.

If the lube is properly applied it should not be thrown off the chain, so you will only get lube on things that touch the chain.

comment I have an older Novara bike wth 26 x 1 1/4 x 1 3/4 tires. Any tires out there with a full whitewall?
@Batman - Which is one very good reason to ignore the inch sizing and go by the ISO.

comment Rear hub bearing replacement
Note that some hub designs have the dust cap as part of the hub rather than part of the cone. I don't know if you can readily buy replacement dust caps for such hubs.

If I Google "26x1-3/4 whitewall" I get a fair number of hits. Some bogus, of course, but that's normal -- you can weed through them. The one thing that's unclear is whether this is for Schwinn-style S7 rims or something else. You should check the existing tires for the ISO size -- something like "44-571". The new tires must match the "571" (or whatever it is) value and be +/-5 or so on the "44" value. Vendors on the web should state the ISO size. (If they don't they probably don't know what they're doing.)

comment Bottom Bracket - Drive Side is Stuck, what to do please?
Longer lever/bigger hammer. If you're sure you're turning it the right direction.

comment Rear hub bearing replacement
Unclear what you're saying. The cone holds the bearings in place, the "cap" around it is just to keep dirt out. Replacement cones (with dust caps) are available for most popular designs. To install sealed bearings you'd need a new hub (and might as well buy the entire wheel).

comment Troubleshooting a bent mech hanger
It appears that the hanger's bent, though the derailer may be bent as well. Sometimes you can straighten things by just grasping and bending. If you have a spare skewer-type axle the thread on that is often the thread in the hanger where the derailer bolt fits, so you can use an old axle (with nuts) as a lever to "accurately" bend it back. Or you can use a small adjustable wrench.

I'll admit that you've almost got me convinced.

comment Why is there a gap between my crank and bottom bracket?
Certainly for a traditional BB there's nothing wrong with that gap. Dunno about newer stuff, though.

comment Riding into a headwind faster than my top speed - how is it possible?
@JamesRyan - You are exerting force on the pedals. (Riding a 40mph conveyor belt is easy, since you only have to deal with rolling friction.)

comment Riding into a headwind faster than my top speed - how is it possible?
The power a cyclist produces is the torque on the crank times the cadence. I don't know about you, but when I'm riding into a headwind I gear down, so that a turn of the crank is not getting me nearly as far as in still air.

comment Riding into a headwind faster than my top speed - how is it possible?
You are wrong with regard to a basic detail. The energy expended in this case is power multiplied by time, not force multiplied by distance. The amount of power required to barely move forward in a 30 mph wind is only slightly less than the power required to go 30 mph in still air.
