The mountainbike was making an annoying click-click-click noise, that
was steadily getting worse. It was definitely in phase with the turning
of the pedals/crank, so not chain or rear end.
Replaced Bottom bracket, cos there was play, and I could feel crunching
going on. Clicking problem still there! It was very metallic noise,
and I could feel it through the pedal when the left crank reached the
top position.
So decided to swap the roadbike and mountainbike pedals over, to try to
isolate the problem. The road pedals are brand new (ie about 15km on
them), and the mountainbike pedals probably have 150km on them tops, so
fairly sure they weren't the cause, although could be SPD cleat related.
But now the problem has totally gone away! So now I have 2 bikes that
are whisper quiet, and smooth as a baby's bottom, but look totally odd!
All the pedals and cranks were fully tightened (after replacing BB -
there was play in the old BB).
So any theories as to what the problem actually was, now that I've
inadvertently fixed it?
I was expecting it to be those strange STX-RC IG chainrings, but
apparently not. Speaking of which... anyone know if these are replacable
with standard 5-bolt compact 94/58mm bcd rings?
