Nasty creaking sound when mashing up extremely steep hill

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Nasty creaking sound when mashing up extremely steep hill

I know this thread should probably go in the wrenching section but i'm more interested in hearing the experiences of some roadies on this one.

There's an extremely steep hill by my girlfriend's house. Its so steep that I can't spin up it in my shortest gear. I don't have a particularly short gear-set either. Some weird old Suntour 12 speed group.

Mashing up results in a creaking sound with each step down on the pedals. Everything has fresh grease in it, the bottom bracket, the rear hub... The chain is regularly cleaned and lubed. I'm starting to think its the frame itself. Sound reasonable?

hard to tell.. first thing I would do is pull the crank arms and re-grease the spindles then reattach firmly. One time I had the same issue and it ended up being where my shifter cables entered the stops, the plastic ferrules were rubbing only when I stood up and was climbing.. it can be a real mystery sometimes.

When was the last time you had your pedals serviced?

+1 re-greasing the spindles.

Ok, I'll check the spindles out. I have not looked at them yet on this bike

Yep, check the crankarms and since you're going to be working down there do the BB once again. Even though you lubed it there may be something in there causing the noise. Check the pedals too, as mentioned above. Finally, and this is going to sound dumb but trust me, loosen and retighten the seatpost clamp. If it's metal to metal, consider a very thin coat of bearing grease.

Mine did this and it was actually something loose in the headset/stem area.

I had a noise like that and it turned out to be the front wheel on a few spokes that seemed to get amplified through the carbon fork. A full retensioning fixed it.

Could it be that the vintage French Jubilee components in your sig are fighting with the Japanese Suntour components in your post?

I had a weird creaking-under-stress noise recently that was fixed by tightening the rear wheel's quick release.

Same for me. Creaking under stress and I didn't realize until I got back to my place that the rear wheel was loose.

I had something similar. It turned out to be the carbon seatpost rubbing against the inside of the seattube.

The other day I had a similair problem that only happened when I stood and put enough torque on the pedals. BAD creaking sound coming from the front fork area... turned out to be the front QR skewer wasn't tightened enough. I thought maybe my fork had come loose but didn't have to tools needed to tighten it until I got home (my allen wrench wasn't long enough).

A lot of ideas... I really don't think its the quick releases. I'm going to change tires later today so I'll double check that.

Frame is steel.

Recently lubed the headset because it has a dead spot in the center.... Didn't work, needs to have the bearing cartridges replaced with loose balls because I really doubt I'll be able to find cartridges for the French headset. In any case I tightened it down pretty well when I was in there so I don't think its the headset.

Could be the spokes or the seatpost I guess... Lots of things to check.

When I had this issue it was a crack in the weld at the BB/right chainstay junction. In addition to all the advice above about greasing stuff, check your frame carefully for cracks.
