I have a Columbus steel De Bernardi frame equipped with Veloce (including a Veloce Ultra-Torque crank set) components, Look Delta pedals (only used a couple years) and Concor steel railed saddle. A couple weeks ago I started getting an annoying creak which seems to be related to down strokes and which sounds loudest when I'm sitting. I've used my trusty torque wrench on my crank and have checked the tightness of my pedals and seat post. But, the noise after being somewhat diminished for a couple miles came back.
take the seat off and ride it to see if that changes the noise, if not swap pedals test ride again, if not. take out bottom bracket and clean the frame from loose particles and clean/lube the cups/bearings/spindle, test ride again. if not, remove chainrings, clean lube metal to metal surfaces and test again. only do one thing at a time and test ride each time. Lube your seat/tube/post.if not start to isolate the stem/bar/fork area in the same manner and the rest of the bike if that does not do it by then
