comment Biking in the winter more difficult?
An important caveat: At temps below about 15F (-10C), if you breathe hard through your mouth (mouth wide open and "panting") it is possible to actually cause frostbite in your throat (with associated tissue injury). And at temps above that (but still cold) breathing hard through your mouth can still seriously dry out the membranes in the throat and cause problems. When it's cold leave the TdF training for another day.

comment Which usually wears faster - wheel rims or brake blocks?
I've never worn out a rim, but a couple of images of failed rims have been posted here, and in those cases it was obvious that the rim was worn out -- there were essentially holes worn through it. I don't know if this is always the case, but I suspect it is fairly normal.

comment 27 1 3/8 tires on 27 1 1/4 rims
Should not be a problem, so long as all the components are "standard".

comment Is the Specialized Sectour Double 2014 a men's bike. Can a women ride a men's bike?
It's a bike. Seems decent. But be sure it's what she wants, and not what you want.

(And note that the Secteur Elite Double comes in 7 different sizes. It's not a "one size fits all" sort of thing.)

comment Is the Specialized Sectour Double 2014 a men's bike. Can a women ride a men's bike?
There is no fundamental difference between a "men's" bike and a "women's" bike, other than women tend to be shorter (on average) and hence need smaller bikes (on average).

comment Vintage 70's Bike info?
@Blam - The cottered cranks place it, I think, prior to about 1980.

comment Should a saddle hurt?
An important point: In the same general area of the anatomy that contacts the seat of a bicycle are muscles that are rarely used except in certain activities (such as cycling). If someone is not at all acclimated to cycling (and doesn't do a lot of other activities such as stair climbing) those muscles will be sore 12-24 hours after a moderate amount of cycling. This is to be expected, and will quickly correct itself with even modestly regular cycling.

comment Should a saddle hurt?
Some discomfort is normal, until your anterior "toughens up" a bit. But if the seat is painful pretty much from the start then probably something needs to be changed. Painful the next day is a bit more "normal", though if it continues the seat may need attention.

The chain should be replaced when it's stretched, the cassette and rings when they're worn. If you service each appropriately you will get maybe 2-3 chains per cassette and 2-3 cassettes per large ring. (But if you replace a cassette you should usually replace the chain at the same time.) And you should be able to get several standard brake block sets per rim.

comment Choosing a handlebar width
In addition to what the others say, slightly wider bars tend to be more comfortable on long rides. And narrower bars, of course, slightly reduce your wind resistance.

comment How to build surge brakes on bike trailer?
Do the math -- Decelerating at so many feet/second squared will generate so many pounds of force. Compare that to the force needed to squeeze your brake lever to a suitable pressure, then figure out what the actual cable pull is.

comment How to build surge brakes on bike trailer?
Clearly one could build a surge brake for a bike trailer. Probably a cable system would be most practical. But given the usual light weight of a bike trailer you would need substantial "travel" (probably 2-4 inches) to apply enough brake force, meaning you need a lever or pulleys to convert the motion to the shorter, more forceful motion needed to drive standard rim brakes.

comment What brand is this vintage bicycle?
I would think that if it were branded for TWA airlines the badges would resemble TWA's logo a bit more. This image shows several logos, and there is no great resemblance. (However, a plausible reason for there being TWA airline bikes of about that style would be for transportation around airports, though one would expect a basket.)

comment How long should brake pads last?
It's all over the map. I get several thousand miles from my brake pads, others get a few hundred. However, it's extremely unlikely that someone could wear out a set of pads in 50 or so miles, unless the brakes were badly misadjusted from the start or the rider was intentionally riding with the brakes on.

comment Does a high MTB seat post risk frame breaking
I often wonder about some of the bikes I see, especially BSOs with long seat posts. But I don't recall seeing any reports of seat post/tube failures.

comment Right crank (Drive side) on the left?
If you leave the sprockets on it may interfere with the frame, since the right-side crank shaft is often longer than the left.
