STEVE-0 Posted January 9, 2012 Report Share Posted January 9, 2012 Hi Guys, Chain snapped mid gap yesterday and bike got thrown about a bit, resulting in a buckled front wheel. Tried to get it true again but I'm thinking the reason I'm struggling is due to the radial build. Been thinking whether I should buy some new spokes and rebuild it with the normal 3 cross pattern (anyone know what the weight difference is, must be minimal). Or should I just stick at the trueing??? Opinions? Cheers, Steve Quote Link to comment Share on other sites More sharing options...
Ali C Posted January 9, 2012 Report Share Posted January 9, 2012 I Think the weight difference is around 10 grams if you only have one side done, might even be less than that. The radial pattern shouldn't really be effecting the truing of the wheel anyway, just work in small amounts and take it from there. Your rim may also be actually bent which could explain your problems, but 3x wouldn't make this much different to fix. Quote Link to comment Share on other sites More sharing options...
forteh Posted January 9, 2012 Report Share Posted January 9, 2012 As Ali said, the radial lacing shouldn't affect your ability to true the wheel, you might find you will have far more success if you partially de-lace the wheel, get tension off the spokes and start again. Its also possible that some of the spokes may have stretched a little so it might be something to watch out for when re-tensioning. Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted January 9, 2012 Report Share Posted January 9, 2012 Sounds like the rim is bent, options: - New rim and keep it radial (10-15% stiffer laterally but less strong than 3x). - New spokes and build 3x, can probably get it a bit truer but it'll never be bob on.

JD™ Posted January 9, 2012 Report Share Posted January 9, 2012 Could you consider de-lacing completely, checking the rim and sort of bodge straightening a bit before rebuilding radially? That'd be the route I'd go down but that's because I'm a cheapskate. Quote Link to comment Share on other sites More sharing options...

I had to do this with a dx32, some spokes snapped and pulled the rim about 3" sideways; was pleasantly surprised when it came true again having released the spokes. You may need to change some of the spokes but the rim could be reusable. Im also a cheapskate Quote Link to comment Share on other sites More sharing options...

It is also worth noting that I too am a cheapskate Quote Link to comment Share on other sites More sharing options...
STEVE-0 Posted January 9, 2012 Author Report Share Posted January 9, 2012 Thanks for the comments guys. No doubt the rim is bent since there is a sharp buckle but pretty sure the rim is not a write off. As for a bodge technique to straighten the rim, what are the options? Grab the hammer? Cheers.
