I understand his explanation of detensioning the spokes on every revolution and the thin spokes stretch more to prevent some of the detensioning. But going with $1 a piece Laser spokes of 14/17 gauge instead of the cheaper 50 cents a piece and readily available 15/14 double butted spokes from DT or Sapim. Aluminum nipples? I thought brass was the standard for reliability. Never rounds off or breaks ever. |

If the rim was very "floppy", then only one spoke at a time on the bottom would be detensioned, but a large number of upper spokes would share the increase. As the rim gets stiffer and stiffer, then the detensioning of the lower spokes gets more uniform and smaller. In the ultimate case of a perfectly stiff rim, then the loss of tension in the lower spikes would be perfectly and symmetrically compensated by an increase in tension of the upper spokes. So you can leave less upward margin in your spoke tension than you have to leave on the downward side. |
