My Planet X has never made a sound, now it creaks like mad. And I’ve noticed what looks like cracks where the chainstays meet the bottom bracket shell. And a odd white line 13″ long down the downtube. You can feel both if you run a finger over them.

Is this just likely to be cracks in the lacquer?

Stripped, lubed and reassembled the chainset and bottom bracket, just in case.

sounds like cracks.

The creaking could be the front mech cable rubbing where it goes through the bb shell/seattube.

I put some plastic tube over mine and it stopped it creaking

frame or coating?

Pics?

Seatpost as well? Or is it only when out of the saddle?

Bar/Stem interface is also well worth a look.

bit of touch up paint and shove it on ebay

Hmmm
Are there folk that can tell? it’s only been raced two seasons and I used my crosser over winter.

Yep, any good LBS will be able to properly diagnose the issue. Where are you based?

check your hanger that can creak like a bastard. take it of run an oily rag over it bit of grease on the bolt etc.

Not the bars/stem
does it out of the saddle.
Doesn’t do it when locked into the Turbos.
It’s that distinctive cracking sound you hear when you free a bolt or loosen a seatpost.

Front mech cable???? I thought it was quite a known issue with PX frames!

Doesn’t do it when locked into the Turbos.

check hanger and the QR cam give it some lube.

You an always do a 10 foot drop or two and that should sort it out for you
