  1. I'm a keen cyclist but very much the beginner in terms of maintainence. I'm
    keen to start learning though and am beginning to collect together various
    tools. I already have a fairly cheap Draper torque wrench with a range of
    20-80Nm which should make it usable for crank arms (40-50Nm) although
    apparently cheap torque wrenches go out of calibration quickly and are
    inaccurate towards the ends of their range. Another problem with it is that
    it will only measure torque on right hand threads which isn't very helpful
    for bottom brackets.

    How essential are torque wrenches for home maintainence and what sort of
    damage can one do without one? I understand that having the correct torque
    for crank arms is pretty important.

    Could anyone recommend a good torque wrench for a beginner (the local bike
    shop has warned me off of beam type torque wrenches)?

    I apologise if this is a basic question but as I say, I'm new the the
    mechanics side of cycling and therefore lacking somewhat in the confidence
    department.

    Thanks for any thoughts,
    With Kind Regards,
    Paul.

    That's ok for Italian thread BBs.

    You're more likely to under-torque a crank bolt than over-torque it
    without a torqge wrench.

    Why is that? Sears sells a beam type for around $20 that covers 0-75
    ft-lb. That would be fine for crank arms and cassette locknuts.

    If you can accurately estimate how much weight you are lifting at any
    given time you can learn to accurately apply torque. If you're a
    chronic wimp or strongarm gorilla maybe a torque wrench is an idea but
    most mechanics I know don't use one very often. Understanding what a
    foot pound is and the dynamics of how threads engage is helpful.

    I'd say it has something to do with the sensitivities of the worker.

    I'm like Magilla The Gorilla without a torque wrench. In fact I bought one
    after frying a number of fittings/screws. To me, the most needful are those
    little alu screws/sleevs that hold the chainrings in place.

    Now that I have a couple of them, I wouldn't tighten many bolts without one.

    Others have probably worked day-in-and-day-out for years without ever needing
    one.

    Beam torque wrenches work just fine, do not go out of calibration,
    measure both left and right handed torque and are cheap. When
    used on cars sometime the nut or bolt is in a position that makes
    it impossible to read the scale. Doesn't happen on bikes.

    The experts at the LBS rarely if ever use a torque wrench because they
    have calibrated hands. They know what torque to apply to each size and
    type of fastener from years of experience. Myself, I don't have that
    experience so I use a torque wrench on any critical fastener (especially
    aluminium threads).

    There is nothing wrong with a beam type torque wrench as long as it has a pivot
    in it's handle. Why has your local bike shop warned you off a beam wrench?
    Any beam type torque wrench will work with either left or right hand threaded
    fasteners and they don't need much in the way of recalibration..

    However, my personal favorite type of torque wrench are the Snap On
    Torqometers. These have a dial readout, 1% to 2% accuracy down to 20% of their
    range. They can easily be recalibrated. They are expensive from Snap On but
    you can find them new or nearly new on ebay for very good prices ($35 - $65).
    A 0 to 600 inch pound wrench will cover many applications. And a 0 to 150 inch
    pound wrench is great for those low torque applications like the newer Campy
    Record hubs.

    I've rebuilt V8 engines with a Sears Craftsman's torque wrench and have used

    Beam torque wrenches are $20 at Sears. They are perhaps not as accurate as
    the clicker type, but they are fine for bikes.

    Get a beam type wrench. They are inexpensive and don't go out of calibration
    like the click type do.

    The "clicker type" torque wrenches go out of calibration easily. They are
    seldom accurate unless recently calibrated because of spring pressure changes.
    They operate by overcoming spring pressure in their mechanism. You should
    always store your clicker type wrench set at the lowest torque setting. I
    prefer either the beam type torque wrench which are simple to calibrate (just
    center the needle) or the dial type torque wrenches (which have an internal
    beam).

  12. Hi,

    I'm not certain why beam wrenches were frowned upon, they just were. I was
    particularly asking about the Park beam wrenches.

    As I've said, this is all new to me and I lack confidence so feel the need
    to be sure I'm starting off on the right foot; I feel that a torque wrench
    would help with this. I don't have a problem using a beam wrench but have
    always tended to take the LBS's advice, I'd be more than happy to hear
    other's views.

    Thanks,
    Paul

  13. Paul:

    I'll add my 2cents. The beam wrench is better than the clicker in 99%
    of circumstances - 100% of circumstances when working on a bike. Why?
    As mentioned before, calibration is easy. You bend the beam until it
    reads 0 with no torque applied. It works on both left & right threads
    also, which certainly helps. I would highly recommend you start with a
    3/8" beam torque wrench. Craftsman is good, but I think you could do
    just as well with a wrench from Parts Plus, Auto Zone, whatever. Also
    get a 1/2" torque wrench if you have spare money. It'll come in handy
    every once in awhile, especially if you work on your own bikes.

    Here are the only advantages I see for clickers:

    1) They work in places where you can't necessary see the display. For
    example, working underneath your car inside the engine compartment.
    Here you just set it and go until it clicks.
    2) If you do a LOT of torque wrench work, it gets old looking at the
    display. It's the same advantage for a different reason. You set the
    torque and go. Example: changing tires at the end of winter.

    I purchased a couple clickers at a "Cheap Tool Sale". I didn't know if
    I could trust them so I've compared them a few times against my beams.
    So far so good, and they cost me a grand total of $22 for both a 1/2"
    and a 3/8" torque wrench. I still don't trust them as much (and I'm
    sure their lifetime will be limited) but they make my life easier so I
    just periodically do a comparison against the beam.

    BTW, I use only the beam wrenches on my bikes.

    MOO,
    Matt

    Hmmm. Who has more credibility here?

    My hands have rarely let me down. When I owned a shop I figured I
    should get a spoke tension gauge so I did. I had been building wheels
    for several years at that point including working at The Cove Bike
    Shop and a run of several hundred for Kona and found that the gauge
    was telling me what I already knew. Cindy Devine didn't have any
    problems winning WC races and a rainbow jersey on bikes I wrenched
    with no torque wrench and on wheels I built.

    From an early age I studied the upright bass and was taught that your
    breathing comes from your center and your center and hands connect in
    an unbroken line of energy. I practiced for hours a day for years to
    become aware of this and compared to the minute adjustments required
    to get even a passable sound with the bow feeling torque is somewhat
    less tenuous. I started racing and working on bikes when I was 13 so
    playing the bass and riding and wrenching and skiing were always part
    of the same thing for me.

    I took exception to Peter C saying across the board that not using a
    torque wrench is a matter of ego. For me it isn't ego and when I'm not
    sure or I feel "unconnected" I'll pick up a torque wrench. That just
    doesn't happen very often.
    ok?
