wheel rebuilding question
I've had a Mavic T138 rear 36-spoke wheel (Dura-ace hub) for about 5 years,
but the spoke holes are starting to crack and it's time for a new rim. I want to use the technique of taping the new rim next to the old one and moving the spokes over, because the spokes seem OK and I want to save some money. My question is: Which of today's rims will work with the same size spokes as the T138? Do they still make T138's? If not, is there a comparable rim out there which uses the same sized spokes? Thanks - Gary |

If the cracking hasn't put you off the T138, they're listed at the Harris Cyclery site: http://www.sheldonbrown.com/harris/rims.html#622 For alternatives, download Spocalc from: http://www.sheldonbrown.com/rinard/spocalc.htm and compare the ERD column. You should be able to get away with a range of a few millimetres either side of your current rim. James Thomson |

Thanks - Gary Another rim database: http://www.fa-technik.adfc.de/Kompon.../Felge622.html I think the T217 or T219 (whatever the current one is) is a same size rim. It's an expensive rim ~$60, but pretty nice for heavy duty applications. |

Sun Rhyno is a drop in replacement. Quite affordable too. Just keep the lacing pattern the same, use NEW nipples and buy or make a nipple driver. If you buy a spare tip for your power screwdriver, you can grind it to make your own nipple driver...a real time saver. -- Weisse Luft |

If the spoke threads are reusable the nipples should be reusable as well. |

Glad you asked. Nipples, be they brass or aluminum, are anodic compared to stainless steel spokes. In layman terms, this means they preferentially corrode when in contact with stainless steel. Furthermore, they are softer than the spokes and get some abuse from wrenching. New rims need new nipples. If you go brass (plated, of course), the cost is insignificant compared to the trouble with the old ones. -- Weisse Luft |
