Strange 'ping'!
I have developed a rather annoying and loud 'ping' which occurs when turning
the bars, I can also feel a vibration through the bars! It's intermitant but annoying. I've recently re-adjusted the headset and whilst doing this removed the stem and applied a little copper grease to the steerer, I put a bit of copper grease on the top cap bolt too. Everything went back together correctly and was tightened up to torque using a torque wrench. I did almost 30 miles on the bike before the ping/vibration began so it may have nothing to do with this. I even took the bike into the LBS to get a professional to check the headset for play and everything seems fine (of course the bike refused to make even the slightest ping whilst in the shop). Any ideas? The problem only seems to appear whilst riding, the brake/gear cable ferruals are greased and there is no obvious source. Was copper grease on the stem/steel steerer interface a bad idea? I'd assumed the same sort of cold bonding/rust problems that might occur with a alloy steatpost in a steel frame, hence the c.grease. Thanks for any thoughts, PJay |

Is one of your control cables straightening over part of its run and then bending again? Is there any unfairness in the cable run? Is a cable (or anything else) binding against the bars, stem or fork? -- (Simon Brooke) http://www.jasmine.org.uk/~simon/ pSchroedinger's cat is blinkstrongNOT/strong/blink dead./p |

Hi and thanks for the thoughts.
I have checked the cables and there may have been some movement particularly where the cables pass through the guides, I've tried to improve things and will have a test ride when this horrid weather has improved! Thanks again. Paul |

Hi Sandy,
No I don't have a front reflector but I do have fittings for a front mudguard which fits into the end of the steerer tube via an expanding wedge, so maybe that's worth looking at. With Kind Regards, Paul |
