Has anyone troubleshooted a creak issue by leaning the bike at an angle and pushing down at the crank at about a 6 o clock position , causing the bottom frame to kind of flex to listen for any type of creaks?.... Is this a normal method of troubleshooting because I was pissed when I saw this done to my bike.

    I've seen that sort of test done. It's a reasonable procedure, when trying to narrow down a creak. (Consider the stresses placed on the crank and frame when you stand and pedal hard.) – Daniel R Hicks Apr 23 '18 at 22:54

    Yeah, its about as reasonable procedure as any. Creaks in bikes are hard to find, since tubes carry sound. But the first thing I check for is physical damage first (e.g. cracks). – Batman Apr 23 '18 at 23:34
  • Ok thank you .That's good to know. Come to find out the cause of the creak was kind of odd. After more troubleshooting I noticed the creak was coming from the seat, after cleaning and re fiber pasting the seatpost, torqued to spec seat and readjusting the seat rails the noise was gone for about 30 min! Looking again at the issue I noticed the seat post was lower than normal I moved the seat post up a bit to the second indication line on the steam and retorqued and oddly the sound has been gone for about a day. I wouldn't think a seatpost height would cause a creak? – adam Apr 23 '18 at 23:55

    I had a seatpost creak that turned out to be a crack in the frame under the clamp. Creaks are hard. – Criggie Apr 24 '18 at 3:22

    Why were you pissed? If you think that puts a lot of force on the frame, imagine what riding up a steep hill at speed will do. – whatsisname Apr 25 '18 at 11:26

Yes. I do exactly this to the carbon bike almost every week just to check when I hear something even resembling a possible creak... well, that is if you ignore that I actually do something similar but even more stressful for the bike every single day; every time I take a corner fast in the woods and feel the tyres losing grip.

So far checking out creaks this way has led me to tighten the BB once and to tighten the crank arms once. However usually it's actually a seat post related creak (sometimes still heard when doing the above). A quick clean and some mounting paste sorts out the post.

If this procedure actually breaks your frame or something, then be happy, very happy. You avoided a serious injury.
