  1. At a recent race I was oogling a friend's new Merckx Team SC. Gorgeous
    blue purple with full Record, including carbon cranks. I asked him about
    the carbon wrapped chainstays, an advertised feature, and he replied
    that they were for vibration damping, saying that having the tubes
    externally wrapped with something did this. He demonstrated the effect
    by knocking on the top tube to produce a sound, then wrapped his palm
    around the tube and knocked again, resulting in a muffled sound.

    I then asked if duct tape wrapped around the bike would have the same
    effect.

    Silence.

    Did you put the duct tape over his mouth? ... maybe that would explain
    the silence. I just couldn't resist. I see duct tape wrapped bicycles
    often, but I assumed it was to cover their identity and make them loook
    real ugly. Maybe those bicycle messengers just don't tell us about their
    vibration reduction solution.

    Well I don't know about vibration reduction. But the rationale behind
    the wrapping of (main triangle) tubes by messengers is to provide
    protection for the bike. Hastily tossing and (free)locking your bike
    against a wall or post 50+ times a day mutilates the frame in short
    order.

    Never used duct tape though. Cork tape was the preference.

    I've always wondered about messengers and locking bikes. Do they lock up
    the wheels, or just the frame? I can see that a lot of messenger bikes
    will have good strong wheels, and some of them will want QR skewers, but I
    can't see taking the time to pull off a wheel or use a separate cable lock
    at each stop, so what's the deal? I seem to remember you're in Toronto, so
    maybe you can give me the local persepctive?

    As for the OP I really don't think you can compare tubes wrapped in duct
    tape to tubes gripped by a fleshy hand. This seems a really foolish
    'proof' that the tape works. Unless the amount of tape you use weighs as
    much as an arm..

    Sky Yaeger, the brains behind Bianchi USA, did this on a frameset at Interbike
    as a JOKE...lots of interest and it's amazing how many frameset makers
    actually do this now and claim this or that about this or that...

    Speaking of bike messengers, I was wandering around San Francisco last
    Friday and noticed a strange trend. Lots of fixies without front
    brakes! First of all, the thought of riding a single speed up some of
    the San Francisco hills gives me pause. But relying on just your leg
    muscles to stop in city traffic? That's, um...somewhat interesting.

    It's important to note that the dynamics of bike use for messengers and
    - let's say for arguments sake - for commuters, are different. A
    messenger will leave his bike briefly unattended dozens of times daily
    in different locales while a commuter's bike will generally remain
    unattended for an extended period time, often at the same location.
    Furthermore, the environs of your working messenger are daytime city
    centers; crowded and active. They along with a hectic schedule usually
    conspire to limit the means to positively secure a messenger's bike
    against theft.

    Consequently, preventing a theft through impregnable security (if such
    a thing exists) is troublesome at best. Fortunately, IMHO, it isn't
    required. It's only necessary to complicate a theft in order to thwart
    it because the constraints of time and conspicuousness are major
    deterrents in of themselves.

    While working, I aimed at discouraging the impulsive and opportunistic
    thief - your typical crackhead or alcoholic looking for funds for the
    next high - not the patient, knowledgeable pro who knows that Phil is a
    hub - not a doctor with a TV show. If he wants your bike he'll get it.
    But, as it impacted me, the threat by the first category was by far the
    greater.

    I'm uncertain what you mean by a 'local perspective.' I assume my
    perspective to apply to other localities as well as Toronto, but I did
    add an URL that applies to the city specifically. Anyway, here are few
    observations from an ex-messenger.

    Firstly: Always lock your bike. "Duh!," you say. Well, surprisingly,
    through laziness, haste or perceived lack of threat, many couriers
    don't always follow that golden rule. I know of 3 messengers who had
    their bikes ripped off (at King and Bay) last summer. All the bikes
    were left unattended for less than 5 minutes in crowded areas in broad
    daylight. All the bikes were not locked.

    Incidentally, once the routine is refined, locking your bike requires
    minimal time and effort. Most couriers have the key to their bike lock
    fastened to a retractable cord (wrapped round the wrist) or an elastic
    bracelet. Once off the bike, the key is literally in your hands: No
    fumbling in pockets or bags. (I still employ this method when using my
    bike to tend to errands.) And the lock (in my case) was kept in a large
    pocket of my 'cargo' pants, located on the side of my thigh, or an
    external loop located on my messenger bag. I only mention this because
    the entire process of dismounting and locking the bike rarely took more
    than 10 or so seconds. It was not a significant cost in time. So
    there's no excuse for leaving a bike unlocked.

    How you lock your bicycle falls into two categories; "Free Locking" and
    locking your bike to an immovable object (utility pole, bike posts).
    The optimal situation is a passing a lock through the frame and perhaps
    a wheel to a bike post/pole. It's the method a typical cyclist employs.

    But, by far, the most common was "free locking" This involves passing
    the lock through the frame or chain/seat stays as well as one of the
    wheels - but NOT securing the bike to an immovable object (because none
    are conveniently available.) If a thief wants to make off with the bike
    he would literally have to carry it away. And those that tried would
    often find themselves surrounded by couriers who knew the bike was
    pilfered or accosted by the bike owner himself chasing him down on
    foot. This was most typically done at the First Can Place, TD Center
    etc... within the city core in business hours. Of course, there are
    bike racks available in the area but if your drop required the use of a
    service or remote entrance then free locking was generally preferred.

    I would generally leave the bike as far as practicable from Subway
    entrances or underground parking areas. If this was not possible I'd
    lock it to the actual Subway stair railing (I did this North east
    corner of Yonge and Carlton). Another example: North side of TD tower
    (55 King St. W) rather than Wellington St side: If free locked your
    bike could be taken down to the rear underground parking.

    The object was to A) avoid leaving the bike unattended in an area
    where one could be alone with it and B) limiting the escape options of
    a thief.

    The type of lock - chain or U - is a matter of personal taste. I've
    used both, but prefer U-Locks because they are stored and handled more
    easily. As far as the security provided by the two designs; both were
    adequate enough *for the purpose*. That is, it would require a thief
    tools, time and a *conspicuous* effort (bystanders would know he was
    stealing) to liberate the bicycle.

    As far as individually locking easily detachable components: Again, IMO
    this wasn't really an issue because of the duration of time that the
    bicycle was left unattended. Even so, those with QRs would often clamp
    them closed (using a hose clamp readily available at a hardware store
    for 50 cents) This, at least required the thief to possess a
    screwdriver and a few minutes to make off with a QR wheel. I never
    resorted to this when working, but frequently did remove my front (QR)
    wheel when locking the bike off hours. My rear wheels employed fixed
    gear hubs; they were bolted on. Also, my wheels were not your boutique
    beauties: 3x 36 spoke with single walled rims. Utilitarian, durable and
    unpretentious.

    On the topic: most of the messengers, including myself, did not ride
    exotic machinery. It has a tendency to attract unwanted attention. In
    fact some of the bikes were *looked like* - as opposed to were -
    beaters. No Trek OCLVs, Lightspeeds with Ksyrium wheelsets etc...

    Occasionally, a theft did occur. And the bike courier community is
    tight knit and nothing infuriates more than a theft; it's tantamount to
    stealing food from someone's plate. Word of a stolen bicycle spreads
    like wildfire and most messengers know their colleagues' bicycles by
    sight. There have been instances of thieves being apprehended by
    messengers (one was careless enough to ride right by epicenter of
    courier culture: Spreads @ Yonge and Temperance) and suffering
    pummellings they'll not soon forget.

    Adhering to the preceding proved successfull for me (for the 2+ years I
    rode). You'll note that none of the methods outlined are exceptional.
    It's important to reiterate that the circumstances of an impulsive,
    opportunistic theft are different from those involving a patient and
    determined thief. And because of the quality of messenger bicycle use,
    a casual or commuting cyclist is often more vulnerable to the latter.

    So, the working messenger's rationale in securing a bicycle obviously
    does NOT apply to the majority of cyclists. It is needlessly risky when
    it's applied to the security of casual and commuter bicycles.

    Not surprisingly, MOST OF THE THEFTS I KNOW OF INVOLVING THE BIKES OF
    COURIERS OCCURRED *AFTER* WORKING HOURS. And the dynamics of those
    thefts mirror exactly the circumstances of bike thefts that occur in
    the greater cycling community. ie. Leaving a bike unlocked on a
    friend's veranda (Riverdale), locking of a bike in the evening while
    attending a BBQ (with a cheap U-lock that was jimmied with a 2x4 @
    Bathurst/Bloor)...

    Here the general precautions for the city apply.
    - Always lock the bike using a GOOD lock in well lighted, well
    traversed areas.
    - Take the bike indoors whenever possible. Always overnight.
    - If you must leave the bike outside overnight then use a POS (Piece
    of Sh_t)
    - Better yet, use the beater in all high risk areas

    etc...

    Yeah, very informative. I'm thinking about doing a stint as a courier, as
    I've always been curious and I think I would be pretty good at it. Also
    it's an excuse to build up another bike.

    By local perspective I just meant that Toronto is notoriously bad for bike
    thefts. From what you said, it might be in my best interests to make my
    bike look as cheap as it is (boutique wheels, what're those?) but still
    identifiable.

    I know a guy who couriers on a fixed with no brakes. When I asked him why
    not add at least a front one he gave me a look like I'd asked him 'why not
    use a foghorn?'

    He's been involved in serious accidents three times.

    OTOH a close friend of mine rides a BMX with no brakes, so not only does
    he rely on his leg muscles but also his shoes to stop in traffic :-) I
    recently built him a road bike to try to convince him of his folly and I
    think he likes it.
