  1. I was wondering if anyone knew what the best crank torque
    setting would be on a Pashley Muni as I want to tighten that
    pesky left hand crank nut up as far as I dare. Looking in a
    bicycle manual it recomends 429Ibf.in/47.5Nm which seems
    alot as my torque wrench only goes up to 200Ibf.in/22.5Nm.
    Maybe I'll need to invest in a new torque wrench. Has anyone
    actually managed to strip a thread by over doing it?

    I wonder why the left hand crank isn't held on using a left
    hand thread like the left hand pedal is. It seems this would
    solve the age old problem of left hand cranks coming loose.

  2. i can't tell you about pashley, but I would imagine they are
    all pretty close to torque settings, give or take.

    On a Suzue, the torque setting you want is 40 foot/pounds, I
    tested a suzue hub to failure and it was between 85-90 foot
    pounds before the threads gave out.

    Are you perhaps reading the required amount of inch pounds,
    or some other measure, and looking at the foot pounds
    measurement on your wrench?

    Unless it is a small torque wrench used for more precise
    things, (little tiny bolts), 40 foot pounds is not a
    very hefty setting and should be easily achieved with
    most wrenches

    According to my handy-dandy converter program 😄 , 47.5Nm =
    420 lbf-in = 35 lbf-ft, and, as Sofa says, although that
    would be in the correct range, is, actually, a little low.

    It looks llike you'll need a different wrench.🙁

    Ok, I am now officially in my normal state of -advanced- confusion.
    Don't try to confuse me, it won't make any difference.
