    I'd have thought it would be one of the major reasons.
    It's the same as leaning forward on your desk, resting your arms on
    it. Leaning forward may not be the same as leaning back, but it's
    still better than sitting straight.

    The mind boggles at the thought of a Pedersen riding position being
    described as any sort of crouch.

    Perhaps some pictures of Pedersens with riders would be useful:

    What is it in particular that's impractical about a Pedersen?

  4. If it were, it might be, but it isn't. People who lean forward
    at a desk typically do so only very slightly, and carry the (small)
    amount of weight on their forearms, with elbows highly bent.
    In a cycling crouch, the lean is more pronounced to vastly more
    pronounced, and the weight is normally carried on the hands
    with elbows straight. That causes the upper limb joint pains
    that bedevil so many cyclists and people who try cycling.

    Tri-bars cause less strain on the arms (though not shoulders or
    neck), but force a deep crouch, which introduces other and often
    serious problems.

    Nobody is claiming that an upright position is ideal, or even
    entirely natural, but it's one hell of a lot better and more
    natural than the unnatural (and even perverse) crouches favoured
    in the UK. And you may deny it, but the UCI crouch IS perverse,
    as the recumbent people have been saying for 80 years.

    Some people can handle those, but many people can't (as shown by
    previous contributions to this thread), and I have met a good
    many people who have tried cycling and given up, or given up
    cycling for more than 10 minutes, because of that.

  5. Then I suggest that you look at advertisements etc. in the era when
    that sort of bicycle was widespread. That sort of handlebar was
    used on the 'sportier' bicycles, specifically to get a more
    aerodynamic position (i.e. a crouch).

  6. This one-off story from 2006 has been popping up a lot. Have there
    been any confirmatory studies, or any followups at all on this? I
    couldn't find any.

    My mind also boggled at the statement that brake cables are unavailable,
    and that cutting off the unwanted fitting from them is a major task.

  8. You appear to be unable to tell the difference between drawings
    produced solely for advertising and fact. In particular, if you
    look at the gallery, the only picture of someone riding one has
    the saddle far too low to avoid knee problems, and is probably
    relatively short (being female).
    What part of "Also, lot of cables come with fittings on BOTH ends"
    did you not understand? Did the missing "a" confuse you?

    Unlike you, I was posting on the basis of actual experience of
    trying to do just the modification in question, and backed off
    attempting to jury rig a longer stem because some of the cables
    I needed were not available in appropriate lengths for love or
    money. As I said in the second half of that sentence, "while it
    it is usually possibly to cut longer cables and jury-rig something
    it is definitely tricky even for a fairly good bicycle mechanic."
    Again, unlike you, I am posting on the basis of actually having
    done that.

    The fact that longer cables are available for some brakes and
    gears does not mean that they are available for all brakes and
    gears, nor that all brakes and gears can be fitted onto all
    bicycles, as you seem to be claiming.

    Which parts require fittings on both ends? I've not met any which aren't
    nipple at one end and cable clamp at the other, though I'm happy to
    believe that there are examples.
    Rod brakes will obviously be out. The old sturmey three speed (with the
    long straight nipple) might be tricky to find, though they were used on
    tandems sometimes. What other weird sorts of cables are there?

    (And let's not forget cable splitters - they'll do for frames which come
    apart, not just for getting length.)

  10. None, but that's how many pre-made cables come - in the sleeve, with a
    disk on one end and a double-nipple on the other. You cut off the one
    you don't need for your bike.

  11. Many, perhaps even most, of the fancier hub gear cables and hub
    brake cables, including SRAM's. Internally, the Spectro S7 shifter
    has a clamp, but replacing a cable is definitely tricky. The hub
    cables are replaceable only in toto, or with special tools. I just
    went out and rechecked my memory, incidentally.

    And, to put this in context, most serious upright riders will want
    a bicycle with precisely that sort of component. There are some
    very solid ergonomic reasons for the association with hub gears, too.
    The combination of Spectro S7 and SRAM hub brakes was extremely
    common on the high-end uprights, until SRAM pulled the plug on the
    former.
    Well, I have encountered at least three diameters (at least two of
    which are still current), and some brakes and gears require specific
    fittings on the end of the outer as well as the inner. And, as they
    are almost all compressed on, moving them from one cable to another
    is Not Fun. My experience is also that commodity cables have too
    much stretch/compression for a few types of brake, but I never
    investigated why in detail.

  12. This is getting ridiculous. You could have checked the factual
    inaccuracy of your claim by a little Web searching.

    I've certainly bought this sort in the past. I think they're the
    cheaper ones because the (reputable) LBS offers single-ended, but with a
    choice of end nipple.

    They also cut the outers to a precise length from a large reel, and,
    which makes them my preferred LBS, include a small handful of outer
    finishers and mouse-condoms.

  14. Yes, that's true, but it's not relevant here, I am afraid. I said
    that many types of cable had fittings at both ends, and could not
    simply be cut to length. I wasn't referring to that sort of cable,
    but to the more specialist ones - which, as I said, are widespread
    for the fancier hub gears and on many (most?) hub brakes.

    It wasn't the claim that many pre-made cables come like that which
    was such bollocks, but the claim that there were no cables with
    preattached fittings at both ends, both of which are needed.
    Which is fine when you want one of the bog-standard types of cable,
    but less use than a chocolate teapot if you need anything else.

    Nick Maclaren.

    If you wont or can't use solderless nipples it's pretty trivial to make
    a nipple from a bit of brass bar and solder it on. Failing that it's
    also simple to join a couple of cables. The only problem likely to be
    encountered is coated cables, which can be a pain to solder.

  19. Been there - done that. Even for non-coated cables, it is NOT
    easy cleaning them adequately, and that task is ridiculously
    beyond the ability or interest of most cyclists, let alone
    potential ones.

    Lastly, if you can join two cables and get them to run within
    their sheath, you are some kind of miracle worker. Even if you
    can long splice wire, that's not enough for brake cables.
