Thanks! However, I am running into a strange difference between two spoke calculators.
Using the table you provided, I enter the data (24, 4, 590) and go to the closest matching hubs (d=58 and offsets 35 and 19,5). I get results 282.79 and 281.30.
However, putting the same data into the DT Swiss calculator, I get 270.8 and 268.3. This is a rather large difference. Am I using this calculator wrong or what is going on? Here is what I enter into the DT Swiss calculator:
Pitch circle diameter = 58 mm
Flange distance = 35mm/19mm
Diameter of spoke hole = 2,8 (I have no idea but the preset rims all seemed to have values like that)
Spokes: Alpine III
No of spokes = 48
Intersections = 4
Nipple = messing 2.0, 12mm
The result is a difference of about 12-14mm. Rather big. Is there really that much inaccuracy in calculators or did I do something wrong?
Edit: spocalc.xls seems to agree with your spreadsheet 282.4 and 280.9.
Just in case, please confirm that I am not doing something wrong here
Why would the DT Swiss site be so much off? Did I just mess up the numbers or is that site inaccurate/"special"?
Edit 2: it seems that the closest length of Alpine III spokes that are available to me are 284 mm - is the 3-4 mm extra length too much or is this amount generally insignificant?
