Slippery Nipples
Hi guys,
Third big ride in a row I've had to true my rear wheel! After taking the tyre off again last night I found that the spoke nipples 'unwind' themselves. So that the spoke is under no tention at all! Am I going nuts here? This shouldn't happen right? The nipples were 'wet', but its not been wet here in a week or so. I unscrewed the nipples, pulled them out and cleaned all the gunk off them and cleaned the threads up. Hopefully this mornings ride will be less eventful! =) cheers, Kim |

The spokes will loose themselves by untwisting. You can reduce the incidence of spoke wind-up by overshooting an backing off as you tighten. That is, to tighten by a quarter-turn, yo should first tighten by a half and then back off a quarter. Try this next time and see if this improves the situation... Ritc -- ritcho |
