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
