Mystery creak
Re: Mystery creak
Still trying to fix this!
Not the pedals, greased the dropouts, changed the block, regreased the seatpost!
The noise definitely appears to be from the chainset so I’ll keep investigating
Thanks

Re: Mystery creak
I had a similar creak & both me & a very experienced bike shop mechanic thought it the BB or chainset.
I finally isolated the noise to the rear wheel bearings. Try fitting another wheel. If the creak disappears you know where to look.

Re: Mystery creak
Have you had a really good check for cracks and fractures all around the frame?
Re: Mystery creak
Check your rear wheel. Clean and lube quick release. Grease hub bearings. Oil spokes at nipples and crossovers. Make sure there's no slack in spokes. Bit of work involved but worthwhile.

Re: Mystery creak
Yep, 1970's Holdsworth, had a good innings. Have a very good look for cracks. Stand adjacent to the bike and apply both brakes. Give a good push on the pedal either side to try and 'twist' the bottom bracket area. See if you can replicate the creak and have a good look / feel for any sign of fracture.
Hopefully it's nothing too dramatic. My tandem had a similar creak and it took a while before I discovered the cracked chainstay.

Re: Mystery creak
My mystery creak turned out to be a cracking seat post which gave itself away by breaking completely.

if you're pedalling hard enough to pull on the bars, you need to check those as well.

Sebastian showed me a trick...
Sebastian is a great Spanish bike mechanic who fixed my bike in Spain.
You strain the bike to find out what's creaking.
He catches the frame and bends it in various directions, including the seat area, stays etc. You find what deformation causes the creak. Then you have it. I'd a helluva creak from my bike. He did that. He said, the problem is in the hub. It was. The cassette body onto which the cassette slips had cracked. A rarity.

Re: Mystery creak
Mine turned out to be the rear mudguard bridge rubbing on the mudguard . . . .
Bit of grease and voila! No creak.

Re: Mystery creak
Although my seatpost is greased and still creaking, my seat tube has a sleeve in it which will be the focus of my next experiment.
Re: Mystery creak
I had this. The sole had a sheet of steel inside that had fractured right across below the ball of my foot.

Re: Mystery creak
I had a creak on a APB Moulton it only happened on bumpy terrain. So I looked on the web for suggestions front suspension needing lubricant was one so lubed that, not that. Seat post nope, saddle nope it was driving me to distraction. Then one day I looked down I have a mini pump attached to the front rack it had shifted downward and every time I went over a bump the suspension would drop and the pump would catch the mudguard. Moved the pump up now no creak. Felt like a right pollock.

Re: Mystery creak
what happened?
creak now gone?
i went back to my summer, geared commuter recently - an old mercian frame built up with 8spd kit - i now remember that there is a small noise from the front end if i stand on the pedals up a hill. think that it is the nose bolt on the XA stem not quite tight but i'll find it. or stay seated

Re: Mystery creak
For my tuppence ha'penny worth; check the B/B axle - crank spider interface.
A thin smear of grease on the Axle taper may do the trick.
