Recommended Spoke Tension for DT Swiss XR 4.1d rim
I want to build a rear wheel using a DT Swiss XR 4.1d rim and 32
Alpine III spokes. Does anyone have handy DT Swiss's recommended spoke tension for this rim? They don't seem to have that information on their website. |

They don't seem to have that information on their website. According to DT all of their rims have a max tension of 120kg which is a bit higher than most recommended spoke tensions for rims. If your hub has a lot of dish in it and you are a larger rider then I would probably approch the 120kg mark otherwise you would be fine if you stayed at 110kg which would put less stress on the rim. Good luck. Steve |

Good luck. Steve Thanks. For the hub, I'll be getting a Shimano FH-M765 (35.8/24.8 center to flange). I'm about 75kg and have a seatpost rack loaded from 5 to 10kg. The wheel is going on my full suspension commuter which I take over some fairly poor roads, so it's going to take some hits. |

I looked up the wrong specs on the hub, it's in fact a 35.35/20.05 center to flange. |

The disc hubs move the non-drive flange in a bit to make room for the disc which will allow tensions to be more even between drive and non- drive. Steve |

100 kgf on the right side rear and front. The same for any spoke, any rim, generally. That's a relatively safe generalization, but it doesn't make much sense from an engineering perspective. A 32 hole downhill rim weighing 900g and laced with 13-14ga spokes should have a much higher per-spoke tension than a 48 hole touring rim weighing 480g and laced with 15-16ga spokes. I know you build a lot of 32 and 36 spoke road bike wheels with 400-500g rims and 14-15ga butted spokes, and 100kgf per spoke is good for that kind of wheel. But some wheels must have less tension and others benefit from more tension. Chalo |

Chalo how does that makes sense? spoke tension is simply that required to prevent the spokes going slack in use - increasing tension does not increase wheel strength or stiffness. and spoke slackening in use is simply a function of the rim deforming at the loading point - a stronger rim will deform less and thus require less tension, all loads being equal. |

Right. But bigger loads-- static or dynamic-- require more spoke tension to support them. and spoke slackening in use is simply a function of the rim deforming at the loading point - a stronger rim will deform less and thus require less tension, all loads being equal. But all loads are not equal, which is why M/Cs get thicker spokes and higher tensions to go along with their stiff and heavy rims. Heavy riders and those who lay a beating on their bicycles require analogous measures. Chalo |
