comment MTB Conversion For Lighter Commuting
A 28 pound bike is maybe a little heavy, but not that much for a commuter. And there is virtually no difference in performance (slight acceleration difference) whether the weight is in the wheels vs the frame.

comment MTB Conversion For Lighter Commuting
Good quality 700C rims can easily carry the load. However, as stated by Arne, they may not fit, depending on how fat a tire the frame is designed for.

comment How do I determine my wheel size
(But the difference between 27" and 700C is so small that tubes for one will fit the other, and manufacturers generally just produce one line of tubes with both nomenclatures.) (A 27" tire will appear to fit a 700C rim but will not stay on reliably.)

comment How do I determine my wheel size
Re your update: The "C" is/was a classification, and there at least used to be "A" and "B" (and, I think, "D") classifications as well, though I don't recall what they meant. Also, you are unlikely to find any 26" or 27" tires to fit a 700C rim -- the 26" tire is (usually) smaller (depends on width), while 27" is larger (doesn't depend on width). However, 28" and 29" tires will (one hopes) always be 700C -> 622 ISO. So mainly check the ISO designation, as that is the one set of numbers that is at all "real".

comment Good beginner workouts on stationary bike
The Expresso I mention has a graphics display that lets you take any of about 30 different routes, with hills and scenery. It does significantly alleviate the tedium, but more important in my mind is the "feedback" you get between "seeing" a hill and increased pedal effort. And the changes are gradual, vs being abrupt as with most "digital" bikes.

Mainly I think that it's hard to motivate yourself to do 2-3 hours on an exercise bike, if only because you can stop at any time. On a "real bike" if you're an hour from home you can't just decide to quit. Besides, a good route (with ups and downs) trains the CV system better and challenges the muscles more.

comment Best practices for commuting with rack & panniers
Well, there shouldn't be grease inside the pannier, but paint can presumably rub off of fasteners. But in maybe 15 years of commuting 20 miles once or twice a week I never had any such problem. A laptop obviously should be padded against contact with any hard surface.

comment Best practices for commuting with rack & panniers
The hook on the strap is intended to hook over the bottom of the rack, near the axle. (There should be a sort of inverted V built into the rack there.) Then the strap is fed up through the slotted square and the guide above that and finally goes through the latch thing at the top. You first snag the strap's hook on the rack, then set the top hooks on the top of the rack, then tug on the strap to pull it taut. When taut, the bag should not pull away from the side of the bike more than an inch or two.

comment Where can I find a replacement part for a seatpost collar?
Take the clamp to a good hardware store. They will have a drawer full of assorted washers and bushings. Likely a brass or nylon washer can be found that will do the job nicely.

comment Why the narrow wheels on comfort bikes?
Well, you started on a false premise, that the above bike, and all "comfort bikes" in general, have narrow tires. As to rolling resistance, it's a complicated issue, but as tires are commonly used (taking into account typical pressures), narrower tires have less rolling resistance.

comment Disc brake rotor size and forks strength
For a given braking force the overall torque on the wheel will be the same, regardless of rotor diameter. However, as the rotor diameter increases, the force placed on the brake components (for a given braking force) decreases.

comment Seat clamp tolerance
If you're talking purely about the collar, there is probably at least 1mm of "play". The seat tube, OTOH, will not have as much, but likely will have 0.2mm.

comment How do I determine my wheel size
Note that if you're ordering a new wheel the ISO number is the number you want. It may be shown as "28/622", for a 700c28 tire, or "xx/571" for a 26" tire with millimeter width xx. The rim you order will have a similar designation, only the first part (the bead seat width) will be much narrower than the tire width (about half).

(In general 27" and 700c tubes are interchangeable -- the difference in diameter is slight.)

comment How do I determine my wheel size
It should be noted that, at least in the US, standard (non-exotic) adult bikes are currently sold only with 26" or 700c wheels. If the tire was manufactured some time in the past 20 years or so a 700c tire will have "622" (the ISO diameter) stamped on its sidewall somewhere. 26" wheels are a bit more variable, and the diameter tends to vary with the width, with ISO numbers between 571 and 597. Older road tires may be 27" (with a 630 ISO number). (Yes, a 27" wheel is larger than a 29" wheel.)

It would be very unusual if there were not markings on the sides of the tires. They often don't seem to make sense, but if you relay them here we can decipher them. Also, of course, see Sheldon Brown.
