replace touring rim
I have a 2004 Trek 520 whose front rim will need replacement- It's gone
around 8k-10k miles, and the sidewalls are concave. The wheel has been perfect and has never had any problems going out of true or breaking spokes, but it's finally wearing thin. I've built wheels before. I read that it's easy to obtain the same rim, tape it to the old one, and then transfer the spokes. That way I can save money by not having to buy spokes. Here are the problems: 1) Trek doesn't make Bontrager Fairlane rims any more. What's a good touring rim with the same ERD as the Bontrager Fairlane (I think it's 607)? Also, at this point, are the spokes fatigued enough that I should replace them? (If I have to get new spokes, then I can build any rim I want). |

Salsa Delgado looks to be a similar profile at 604mm, so could work if the spokes are flush with the ends of the insides of the nipples. Also, at this point, are the spokes fatigued enough that I should replace them? Secret sources tell me your spokes are fine. |

Velo-Orange is pushing it as their 650B rim of choice, and the 700c version has a 607mm ERD. The Salsa Delgado Cross that Landotter mentioned is an excellent touring rim - it's what I built the wheels for my Surly with, and they held up under 300+ lbs of bike+rider+cargo without complaint. But if you go with something with a smaller ERD, beware the spoke nipples bottoming out, If you need spokes, I always get them from RBT regular Dave Ornee. Search ebay for "Sapim" and there they are. Best spoke deal going. |

What's a good touring rim with the same ERD as the Bontrager Fairlane (I think it's 607)? According to my cursory research, it looks like the Bontrager Fairlane has a 604mm ERD. The Alex DM18 has a published ERD of 606mm. It's a better, stronger rim than the Fairlane, and it costs so little that it will make you wonder what's wrong with it. But there's nothing wrong with it. http://www.alexrims.com/product_deta...=4&cat=4&id=96 http://www.jensonusa.com/store/product/RI308A06.aspx (Note that every specimen I have ever seen is plain matte silver with single eyelets.) The Alex Adventurer (another excellent yet inexpensive rim) has an ERD of 603mm. Its only drawback in my opinion is that it's black with machined sidewalls. http://www.alexrims.com/product_deta...=4&cat=4&id=93 http://www.jensonusa.com/store/product/RI308A07.aspx Also, at this point, are the spokes fatigued enough that I should replace them? Probably not. If no spokes have broken yet, keep them. Chalo |

But if they're recessed a mm or two into the nipple, it'll be good. They got the Weinmann at Niagra for $22. http://tinyurl.com/6j8kyz Can't beat that. Just the name makes me wanna put on some crochet gloves! |

I just shined up the wheel set I built for the doer of all things that has the DM18s, and the shortcomings for the OP would be that they're gonna be 100g heavier than the other rims mentioned. 100g stronger as well, so a bonus! A little wider than the rest. I run 30mm IRCs on mine which is a fine combination. If you wanted to run narrower tires, they're not a good choice. (isn't 30mm narrow?) |

On Spocalc, the Fairlane is listed as 607. Where did you see it listed as
604? If it's 604, then that greatly changes the choice of rims I can use. Also, at Jenson, the DM18 was listed as 610. Where did you see it listed as 606? Thanks - Gary "Chalo" wrote in message ...

The ones you get in the US have eyelets and I used them as a direct replacement for a Rigida non-eyeletted rim with an ERD of 610mm. Spokes ended up bang on. I'd say it's a 610, so do a couple other sites. Alex does a couple different variations of this rims, AFAIK for different markets, but if you're getting it in North America from QBP, it'll be 610mm. |

I built a set based on this quoted ERD of 606.4 mm with good results. "Good results" to me is when the end of the spoke is within the bounds of the slot in the nipples. The DM-18 rims I used have eyelets and there was some variation around the rim, but when completed all spokes ended up in the "good results" range without changing any spokes. -- daveornee |
