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.)

comment Can someone help me identify this bicycle?
I see probably more images without front shocks than with.

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.

comment Do wider tires wear better?
I get over 5000 on my 700x35s, running mostly Forte road tires. I generally don't run until the cord is showing, but until the tire "feels thin" in the middle.

comment How do I reassemble the rear gearing after fitting new tyres?
Which side is this on, the right side where the sprockets are, or the left side? Also, do the slots that the axle fit into run horizontally, vertically, or diagonally?

comment How to ride to work without sweating?
@plh - "PackTowl" is one brand, sold largely to campers. There are others that are sold to swimmers. Made either of "microfiber" or synthetic chamois, most can be used dry or they can be wet, wrung out, and used damp. Even when wet, if you wring them enough, they will dry you off pretty well, without another towel.

comment Can someone help me identify this bicycle?
Impossible to tell for sure, but it appears to be a 6 or 7 speed rear cassette. V brakes date the bike to after 1997. I don't see any images online that appear to have original equipment shocks, though many have the "pretend" bellows below the headset. Also don't seen any images online of that sort of pseudo Mixte frame unless I drop the "F" from the designation. This appears to be about the closest: epinions.com/pr-Bikes-Cannondale_Adventure_400_Mixte?sb=1

comment How can I properly replace the hose on this older Schwinn pump?
FWIW, after my Topeak chuck failed this summer I bought this replacement assembly -- just needed the chuck, but the chuck alone was out of stock and the price difference wasn't that much. It might work for other pumps, perhaps with some surgery to the hose.

comment Best practices for commuting with rack & panniers
Well, folks rarely put 50-80 pounds of gear in a backpack (and then ride a bike with it). The main point is that stopping distance is not dramatically increased. It FEELS like you're driving a truck, but stopping distance is still fairly normal.

comment Best practices for commuting with rack & panniers
@gerrit - But the papers you slid in alongside the laptop are pretty light, and will often tend to work themselves up as you ride on a rough road. Or the box of macaroni in the top of that bag of groceries may decide to make a break for it.

comment Best practices for commuting with rack & panniers
But it's stupid to have an open pannier anyway, since stuff can jump out of it on a bump. ALWAYS securely fasten whatever closures the pannier has.

comment How to center a quick release rear wheel regularly
Yeah, and cutting through the tire is probably a bigger PITA than cutting through the rim.

@plh - A sport towel is reusable, and hence "free" if you reuse it enough.
