    Park tool tension meter

    Anybody knows if Park Tools TM-1 fits ERTO 406 wheel?

    What about 406 wheels with DualDrive hub (bulkier IGH hub = shorter spokes).

    Thanks,

    Kam

    no, not really.

    don't worry, it's harder to screw up smaller wheels than big ones.
    Food for thought: if you aren't dead by 2050, you and your entire family will be within a few years from starvation. Now that is a cruel gift to leave for your offspring. ;)

    If you're following proper wheelbuidling procedure. You shouldn't be significantly off in tension of the wheel to make any difference.

    in fact, if the spokes cross at all, you'll get very inaccurate readings. Better to pluck the spokes.

    Precisely the opposite is true. Crossings make the tone different but don't affect tensiometer readings.

    Try building a pattern that has crossings at different distances, like a 3leading-3trailing. With the spokes equally tight at the nipple, the sound is vastly different for different spokes.

    On my TM-1 the distance from the outside edge of the 2 pegs(7mm dia) is 109mm, 102mm center to center. Max width of the metal plate it is mounted on is 121mm.

    What is the length of the spokes? I am not clear if the peg can wrest on the nipple.

    Crossing may interfere with the center peg of the TM-1.
    2000 Montague CX, I do not recommend it, but still ride it.
    Strida 3, I recommend it for rides < 10mi wo steep hills.
    2006 Rowbike 720 Sport, I recommend it as an exercise bike.
    1996 Birdy, Recommend.
    Wieleder CARiBIKE (folding), decent frame.

    You should be taking your measurements at the spoke closest to where they 'cross.' Not close to the rim. Just saying...
    How do you keep an idiot in suspense?
