  1. Would like some information on how to prolong chain-life and lower
    chain-maintenance via chain-guards and/or enclosed chain baths.

    Since chain-care is the most frequent service needed (except for air in
    the tires), and since its one of the dirtiest jobs to do -- it puts
    "civilians" off from taking up the bicycle as a Transport alternative.

    -- How difficult would it be to enclose a chain on a standard MTB or
    hybrid style commuter bike with derailler?

    -- How difficult on a bike with hub gear?

    -- Even without an oil-bath enclosure, it seems that a fully-wrapped
    chain (Euro-style) would prolong life (keep dirty away) and reduce
    maintenance. WHY is this not more readily available (in the US
    market)?

    I spend more time on flat repair than chain maintenance, and I suspect
    that many others do as well.

    I don't think that chain maintenance or chain filth is even a blip on
    the long-range radar for the average non-rider. The real issues are
    convenience, effort, speed, weather issues, vehicular traffic hazards,
    cargo capacity, status, and the distances involved. In a town of
    10,000, most anywhere should be reachable in a reasonable time on a
    bike. In a city of a million, laid out in the typical spiderweb
    manner of a car-as-mass-transit US city, it is not unusual for the
    distance to some common destination to exceed 20 miles, with a
    non-bike-friendly path between them as the only feasible route.
    However, assuming for the sake of argument that all of these large
    issues had suddenly been rendered inconsequential, and that many
    millions of US citizens suddenly found themselves wanting a bike as an
    alernative to the automobile for local running about, then a cleaner
    chain drive system might be a selling feature in some cases for the
    same reasons that it long has been in other places.

    Very. In fact, worse than that. I've modeled what it would require,
    and the resulting monstrosity would not be acceptable.

    -- How difficult on a bike with hub gear?

    A fully enclosed chain system for a single-path chain is easily done
    and common in Europe and Japan. No one uses an oil bath. It would be
    absurdly expensive and would make flat repair into a much more
    difficult task.

    Quoted message said:

    -- Even without an oil-bath enclosure, it seems that a fully-wrapped
    chain (Euro-style) would prolong life (keep dirty away) and reduce
    maintenance.

    It does. The 20-plus-year-old Puch on my patio is proof of this; it
    still has its original chain, and has not been lubricated all that
    often.

    Quoted message said:

    WHY is this not more readily available (in the US
    market)?

    Because the average US consumer either wants a cheap bike (ergo, no
    extra fripperies like a chain guard) or wants one with lots of gears
    and a der system (ergo, once again, no chain guard), or wants a
    racy-looking bike (ergo no chain guard) or a mountain bike (ditto)
    or...anything *but* the typical European bike. The vast majority of
    bikes sold in the US do not have fenders, either, for that matter. Or
    generator-driven light systems. Or a tire pump. All of these are
    common on European bikes.

    But to focus on the single isse you were addressing, in places where
    bicycles are already regarded as a more serious form of transport and
    living space is less capacious than is typical in the US, the need to
    store a bike cleanly in one's own apartment or room has made such
    chain guards (and chain alternatives) commonplace. Perhaps we will
    see them more widely adopted here at some point, but only time will
    tell.

    Pretty difficult, but perhaps you're a mechanical designer with a couple
    thousand bucks to spare and if you CAN get one to work then you could market
    it. No one would buy it because a $20 chain that you replace once or twice a
    year is hardly an inconvenience.

    Quoted message said:

    -- How difficult on a bike with hub gear?

    Not too bad, commuters were made with enclosed drive chains and internal hub
    gearing. Trouble is that in Europe most people live near where they work. Or
    they live close to public transportation that is very cheap and efficient.
    Here, for instance, in the last 40 years I've only worked within 10 miles of
    where I worked for a total of about 4 years. The rest of the time it wa
    20-30 miles which makes bicycle commuting impractical. Though a friend of
    mine did a 30 miles one way commute every day for about 7 years. He was
    plenty tough but he didn't have much of a life off the bike.

    In the USA most bicyclists are recreational riders. That means performance
    and efficiency is more important than chain wear.

    Perhaps some sort of permanently sealed and lubricated chain would be a
    better solution.

    Perhaps some sort of permanently sealed and lubricated chain would be a

    Derailleur chains require more side flex capability due to chainline
    misalignment than can be engineered into a sealed-roller chain, and no
    current sealed-*roller* chain also seals the sideplates against wear
    at the rubbing faces, anyway. Also, current sealed roller chains as
    used on some motorcycles and industrial equipment exact a higher
    operational drag penalty than an unsealed chain due to the tension of
    the seals.

    In other words, there are and will be no sealed bike chains for
    der-equipped bikes.

    I don't think there really are any of those these days. It seems to be
    a peculiarly US thing - most cars sold in the UK have oil change
    intervals of 9,000 or 10,000 miles (one of ours is more like 16,000
    miles although the VW-spec synthetic oil it requires is fiendishly
    expensive).

    I smell a US conspiracy to sell more oil, which the Rest Of The World
    hasn't fallen for :-)

    Would like some information on how
    to prolong chain-life

    Lately I have been running the chain as dry as possible as oil and dirt
    seem to go together. I spray the chain with engine degreaser and spray
    with high pressure sprayer. After a few days I repeat the process.
    Eventually the chain gets so dry that it seems to want some oil, so I put
    a little on it, and the chain is soon dirty again, so I wipe off the
    excess oil and or dirt with a rag. Eventually I get around to the
    degreaser/high pressure wash again.

    The idea is to have the chain as clean as possible with as little oil as
    possible. I read today on one site where a fellow uses a 50/50 mix of
    synthetic motor oil and mineral spirits. Sounds good to me. Lately I
    have been using a 50/50 mix of 30 WT oil and lighter fluid for general
    lubrication and so on. I think I will change it to charcoal lighter
    fluid and oil, as Ronsonol is a little expensive as an oil thinner.

    The theory of the thinned oil is that you apply a small amt and the
    volatile part goes away, leaving a thin coat of oil. As always, wiping
    off the excess every few rides gets rid of extra oil and leaves less
    places for dirt to stick. Oil on a chain really attracts dirt, but
    conversely riding the bike can help clean an almost-dry chain.

    Would like to try the petroleum-paraffin method sometime but have not
    gotten around to it. Paraffin has a lot of lube properties but is drier
    than oil and is said to flake off when dirty. But the truth is that
    running the chain on minimal oil has made chain maintenance a trivial
    problem.

    In a way, this illustrates my point; the average American bike buyer
    is not *currently* riding, he's either getting a first bike, or a new
    one after a long hiatus. The x-mart-as-source phenomenon is both
    symptom and malady; the uninformed buyer, if he or she steps into the
    lbs to shop, gets a bad case of sticker shock by comparison to x-mart.
    The thought that there's a reason for the price differential might
    cross their mind, but instead of trying to find out about it and
    seeking to make an informed choice, the more common reaction is to
    think "Well, I probably don't need a bike as good as *these*, I'll
    just get the one from $BIG_STORE, it's a lot cheaper, and I'm sure
    it'll be good enough for what I'm going to do." If as too often
    happens, the one critical component on the cheap bike turns out to be
    as awful as my experience would predict (specifically, that the seat
    is unsittable) the thought becomes a self-fulfilling prophecy; the
    uncomfortable bike gets ridden very little, for which no particularly
    high level of quality is needed.

    If x-mart bikes came with decent saddles and pre-purchase guidance
    most of the time, I suspect that they'd get ridden a lot more. Most
    of them are, in point of fact, mechanically quite capable of giving
    years of satisfactory service to the fairly frequent but casual rider,
    but their level of comfort causes them to stay parked instead.

    Of course, I should also note that for the rider who's had a long
    absence, or who is just acquiring their first bike, the real issue
    with saddle comfort is getting used to a bike saddle *at all*. The
    new rider should be given the firm admonition to ride short distances
    at first, adjusting the seat angle and position as seems needed until
    it's reasonably comfortable, and then try longer distances. If, once
    the rider has begun riding farther, the fit still seems sub-par, then
    a different saddle can be swapped on. It is, however, remarkably
    difficult to convince a Roadmaster Mt Fury owner that they should buy
    a seat that costs 80% of what they paid for their entire bike, and a
    $42 saddle is far from being a high-end unit...

    Dear Lou,

    Elsewhere in this thread, posters are complaining that
    WalMart sells cheap bicycles in the U.S. without any
    "guidance" as they call it.

    In the Netherlands, how much fuss would you say that the
    hordes of typical commuter/city bicyclists make about
    getting their bikes?

    That is, do most bicyclists in the Netherlands spend lots of
    time comparing brands, discussing details with bicycle
    shops, getting guidance, and getting fitted?

    Or do they just walk in, pick a bike that they like, and
    ride off without much more thought that WalMart customers?

    Well I am not really sure I understand how my pant leg thing relates to
    people buying bicycles at the local x-mart,

    The point is that you didn't recognize it as an issue until *after*
    you bought the bike. The same is likely to hold true for a lot of
    others. They probably don't think about that problem when
    considering a bike; the others I cited would be bigger factors in
    their deciding that a bike isn't suitable for their needs.

    Quoted message said:

    but I do understand about the
    pre-purchase guidance. It is non-existent at the x-marts. The person that
    works in that department probably has very little or no experience with
    bicycles. So as a result the buyer gets no real advise. And the person that
    that assembles the bikes probably never even see's the buyer so you can
    forget about properly adjusting the bike for the rider. And you said it
    about the cost of a comfortable saddle in comparison to the cost of the
    whole x-mart bike.

    Yup, I agree on all counts. The bikes are in the toy department at
    Wal-Mart for one thing (which tells me entirely too much about their
    opinion of what they're selling), and the bike sales area isn't in the
    same part of the store as the bike assembly area...which is outside,
    in a corner of the garden shop in most cases. That's if they even
    *have* a bike assembly area; many of the Wal-Mart stores seem to get
    huge shipments of bikes that are assembled and hung from the rafters
    all at once, and then pulled down over the course of the year as units
    get sold from the display rack.

    I don't know if you ever visited the Netherlands. Then you would know
    that we have a lot of bicycles. Every citizen has at least one bicycle
    and lot of people commute. So we have a lot of bikeshops who deliver
    good advice, a wide range of good quality bikes and good service. Before
    spending about 700 up to 1200 euro a lot of people do spend quite a lot
    of time comparing brands, discussing details with the bikeshop. For most
    people buying an new bike is a happy event. Fitting is the weak part
    with commuter/citybikes. Mostly they only determine the correct
    frameheight and the customer figures out the rest on a trial and error
    basis.

    We have those too and we have also department stores selling low end

    it seems that a fully-wrapped

    Look inside and they are full of dirt, muck, junk, crud, and lastly
    grit.

    Mine isn't.

    I would maybe use one if I spent all day on unpaved roads as in
    3rd world countries where these enclosures are found, and not even then
    unless there was blowing dust. I don't think they serve a real purpose
    on paved roads.

    They keep the chain quite clean and apparently extend its life quite a
    lot. They also keep pant legs and furnioture from getting marked by a
    greasy chain, while still allowing that chain to be properly
    lubricated.

    Here in the Netherlands a fully-wrapped chain is standard for 80% of our
    commuter/city bikes and with reason. Never knew we were a third world

    Dear Lou,

    Elsewhere in this thread, posters are complaining that
    WalMart sells cheap bicycles in the U.S. without any
    "guidance" as they call it.

    In the Netherlands, how much fuss would you say that the
    hordes of typical commuter/city bicyclists make about
    getting their bikes?

    That is, do most bicyclists in the Netherlands spend lots of
    time comparing brands, discussing details with bicycle
    shops, getting guidance, and getting fitted?

    I don't know if you ever visited the Netherlands. Then you would know
    that we have a lot of bicycles. Every citizen has at least one bicycle
    and lot of people commute. So we have a lot of bikeshops who deliver
    good advice, a wide range of good quality bikes and good service. Before
    spending about 700 up to 1200 euro a lot of people do spend quite a lot
    of time comparing brands, discussing details with the bikeshop. For most
    people buying an new bike is a happy event. Fitting is the weak part
    with commuter/citybikes. Mostly they only determine the correct
    frameheight and the customer figures out the rest on a trial and error
    basis.

    Or do they just walk in, pick a bike that they like, and
    ride off without much more thought that WalMart customers?

    We have those too and we have also department stores selling low end
    bikes in the 150-200 euro range.

    Lou

    Dear Lou,

    Yes, pictures posted here have shown that bikes are
    impressively more popular in the Netherlands than in the
    U.S.:

    http://groups.google.co.uk/groups?q=carl+penguin&hl=en&lr=&group=rec.bicycles.tech&scoring=d&selm=8bbde8fc.0312151625.18fde916%40posting.google.com&rnum=1

    The picture that Derk linked is no longer up, but it showed
    what looked like a bicycle version of a penguin rookery.

    Would you hazard a guess as to what percentage of bikes in a
    triple-decker Netherlands bike parking lot are the low end
    bikes that you mention?

    That is, I'm wondering if most people are commuting around
    the cities on 700-1200 euro bikes bought in the local bike
    shops, or if they make do with the cheaper, more generic
    bikes in the 150-200 range?

    If you find yourself in one of those monster bike parking
    lots, you might take a few moments and make a rough tally as
    you walk past a hundred bikes or so.

    (At the Pueblo library bicycle rack, one was a WalMart
    child's single-speed BMX-shaped thing, while the other was
    an ancient 5-speed touring bike of some now-extinct breed. A
    spring snowstorm left it unclear whether both had been
    abandoned days ago.)

    -- How difficult would it be to enclose a chain on a standard MTB or
    hybrid style commuter bike with derailler?

    Very. In fact, worse than that. I've modeled what it would require,
    and the resulting monstrosity would not be acceptable.

    I understand that "this monstrosity" (an oil bath) would of necessity
    be large in three dimensions. But, something flexible, like latex, yet
    centered/ supported on a polycarb or metal frame should be able to
    contain/repell the clean-chain enviornment. If just an enclosure,
    without inside fluid, then a disconnect in the housing should allow for
    relatively easy access for tube or tire swap. It would also add weight
    to the machine -- something the typical racing cyclist is loathe to do,
    prefering their immaculate 19# exotic animal to something more closely
    resembling a piece of transport equipment.

    Many of the Euro-style "roadsters" weigh in at 35-45#, from what i
    understand. Yet this is only a minor inconvenience (with adequate
    gearing) to the still-dirty velcro'd trouserleg, the once a month chain
    clean/re-oil chore (my flats seem to come in swarms; months at a time
    flat-free, followed by flats, and flats-upon-patchs, etc), and the
    chain-replacement chore (1500-2500 mi) for mere city street commuting..

    But then, I load up my bikes with racks, fenders, lights, horns,
    water-bottle cages, baskets, radios, computers, locks and whatever
    stikes my fancy. To me, the (in)convenience of a trouble-free chain
    would be worth adding a 'simple' monstrosity.

    Well I am not really sure I understand how my pant leg thing relates to
    people buying bicycles at the local x-mart,

    The point is that you didn't recognize it as an issue until *after*
    you bought the bike. The same is likely to hold true for a lot of
    others. They probably don't think about that problem when
    considering a bike; the others I cited would be bigger factors in
    their deciding that a bike isn't suitable for their needs.

    Oh okay I get what your saying now.

    but I do understand about the

    that assembles the bikes probably never even see's the buyer so you can
    forget about properly adjusting the bike for the rider. And you said it
    about the cost of a comfortable saddle in comparison to the cost of the
    whole x-mart bike.

    Yup, I agree on all counts. The bikes are in the toy department at
    Wal-Mart for one thing (which tells me entirely too much about their
    opinion of what they're selling), and the bike sales area isn't in the
    same part of the store as the bike assembly area...which is outside,
    in a corner of the garden shop in most cases. That's if they even
    *have* a bike assembly area; many of the Wal-Mart stores seem to get
    huge shipments of bikes that are assembled and hung from the rafters
    all at once, and then pulled down over the course of the year as units
    get sold from the display rack.

    Well I don't know how they do it now, but in the *old* x-mart days they used
    to just have them in crates, and when a buyer purchased one, they put it
    together, and you had to make a return trip to pick it up.
