be gone, creak!
No news to most of you, but a less than really tight rear quick release can cause a creak that sounds exactly like it must be coming from the crank or bottom bracket. Especially in a titanium frame bike.
Even more difficult when there's a 'red herring'... a slightly loose chainwheel screw. Or... a PowerTorque bottom bracket with it's typical (and normal) tiny bit of play. Ah, bikes.

Yep, have had the chainring bolt creak. Had it for months, actually. But only under real power. Since it was on a steel frame, I think I assumed that my cassette had some play. One morning, pre-World Famous Montrose Ride, I was wiping down my chain and noticed that not one, but 3 bolts had unthreaded

You really don't want to know.
Safe to say I was about ready to pull the crank and BB before I overcame the 'no, that can't be it' thinking and tried tightening the QR. Sure enough.

Yeah, but that was the 'red herring'. The QR was the culprit.

Oh, it's always the QR on a Ti frame. Gotta use Campy or Shimano QRs always!

I had a creak on my steel Santana Tandem that I found by accident after I checked all the usual suspects and had given up... A seatpost collar that wasn't seated completely was the cause.

The more creaks I've had, the more I've come to realize it's literally impossible to tell where the creak is coming from just by listening.
I've had everything creaks... spokes, QRs, seatpin (or was it the clamp?), crank bolts, SHOES (that was fun), front shift bosses, spacers/stem, and most recently - cable housing rubbing the bottom of my stem. Hunted and pecked for hours in the garage, but finally figured it out mid-ride last weekend.... swiped some spit between the housing and the stem, silent bike again. Every one of these creaks have all sounded absolutely identical. They all sound like the BB. And... never once has a creaked turned out to be the BB.

On my alloy frames (alu and Ti) the creaks always seem to emanate from the headset. That drives me more insane than thinking it's from the BB. Teeth, ya kno.

Good guys for putting up with me (I'm local, so I can just ride the bike right in there)

Not sure if I should be happy or sad that the source of the loudest creak in my drivetrain is my knee.
Doc says it's harmless, but sometimes you wonder . . . |

Speaking of headsets, I did have one long term creak on my CAAD10. Never suspected the headset as the bearing cover and spacer weren't loose. Thought it was a similar situation to the cables being too tight or housing rubbing the stem. Finally took my stem off and noticed that the compression plug had slipped slightly. The creak always occurred under extreme load (climbing out of the saddle on 15% grades) but had become more common. Creaks, man. Last edited by beeatnik; 03-10-2016 at 10:44 PM. |

Last year I was 100% certain the bottom bracket on my Ti frame needed adjustment/replacement since I only got creaking when I was out of the saddle. Mechanic found out it was due to improperly tightened front QR. Shows what I know...
