Replacement for rim with offset spokes
I'm not sure if I'm using the correct terminology but I have a Trek 7000
that has offset spokes on the rear wheel. By offset I mean that the spokes don't connect to the rim along the centerline, but off to one side (all spokes offset to the same side). I had the need to replace the rim because of rock damage and my bike shop threaded my hub and spokes (I think they were my old spokes) on to a new rim that wasn't offset. Is that an error on their part? Should a bike that has an offset rim only be replace with an offset rim or could a regular rim be used. I'm guessing that the offset rim works in tandem with a special offset hub (and spokes). It seems that an offset rim would require longer spokes on one side than the other. I'm asking this because I went for my first ride with the new rim and it was a disaster. Half way through the ride I knew something wasn't right. Most of the spokes were now loose (some would move as much as an inch). I've been very happy with the bike shops mechanical skills up to this point, but this latest work has shaken my confidence. Now I need to know what kind of rim to replace my offset with (links to appropriate repalcements at nashbar, etc would be appreciated.) Thx |

There's only 1-2mm difference in spoke length between spokes for an OCR rim and a normal one. It doesn't sound like they properly tensioned the new rim which is the main reason things loosen up during riding. Or they ran out of thread but you would see a considerable amount of spoke protruding from the nipple inside the rim if this is the case. If you are really concerned find a better wheelbuilder in your area and have the spokes replaced as well. New ones are less than a buck a piece. Mike |
