Advices for Uukha products choice and use

  1. Brace height:
  2. Tiller:
  3. String:
  4. Arrows:
  5. Noise,vibrations:
  6. Other adjustments:
  1. Brace height:

    We recommand to respect the value in a +-10mm range.

    Lower the brace height if you focus on speed, increase it for stability and comfort.

    Brace heightUx100,Hx10,Ex1,X0Vx1000
    70"232 mm225mm
    68"225 mm218mm
    66"218 mm211mm
    60"199 mm
  2. Tiller:
    Tiller is the difference between the distance top limbs / string and the distance bottom limb string.
    For Uukha limbs common settings between 0 and 6 mm are correct too.
  3. String:

    The chart indicates the number of strands we advice depending on the weight measured at your draw length and the string material.

    Length to obtain adviced brace height*:

    measureaccording to AMO**direct***according to AMO**direct***
    70"1682 mm1673 mm1709 mm1700 mm
    68"1626 mm1619 mm1654 mm1647 mm
    66"1577 mm1572 mm1606 mm1601 mm

    * on 25" UproLite riser (and most of 25" risers)
    ** according to AMO: without twist, under 100# load, outside two 1/4" diameter axes inserted in loops
    *** direct measurement: string twisted with 20 turns, with moderate tension by hand on a table (this method is easy but less precise)

  4. Arrows:
    The Uukha limbs push arrows a steadier way. Therefore, you can choose - with equal power and draw length - more flexible tubes than for laminated limbs. We advise to respect the tables’ indications of the tubes manufacturers, without shifting towards one or two lower spine cell in the table .
  5. Noise, vibrations:
    When the bow is correctly set up, the noise is very short and dampened (a bit like a silent gun) . Limbs stop at once with very few oscillations.
    If it's not the case:
    1. Check tiller screws are between medium and max setting (the more the better)
    2. Check brace height is what we advice : see here
    3. use a string made of BCY 8125 or better astroflight (I don't mean other brands don't work but those 2 ones work well)
    4. last and very important, use a good stab with a good damper and a mass at the end.
    5. limb saver has never been for us a solution, we have always been able to find a solution with points 1 to 4.
