When I press on the back there's a loud crack - and when I pull up again it does the same
Don't think the saddle is cracked - thought it might be the seatpost head slipping
Will I die if I ignore it?
grit in the runners/rails
Don't think so - it's a veritable crack
I've had em off and cleaned down and can't see any sign of damage to the saddle or the rails but its an old post so thought it might be slippage
had this with a raceface. it was the glued joint between tube and head
Cheers - sounds reasonably terminal when it happens and doesn't inspire confidence when the seat slips back
I had a similar occurrence but I think it was a curry I ate.
Rubbing goose fat into your groin helps. Not with the seatpost squeaking, but it helps.
If my saddle starts to smell when it happens next ill mebbe lay off the curry the night before I ride!
Would a swan do?
In a serious note it's really likely to be the seat rails moving every so slightly against the clamp.
Most of my saddles do it after a dry spell, and ti seems the worst for it. You rock the saddle backward and it cracks and push the other way and it cracks again.
Its just movement in the saddle rails, take the saddle off, clean the rails and then wipe some grease or carbon compound on the rails. Reassemble and toruq up, it'll be fine 🙂
Mine does this, a proper 'crack' rather than a squeak.
I managed to stave it off by taking the seat post out, standing it upside down and spraying WD40 into the 4 points where the seat rails connect to the saddle, and around the points where the seatpost grips the rails. Lave it overnight and it usually quiets it down for a while.
I've got that mahoosive hope seatpost which seams pretty solid, so i'm pretty sure its the saddle rails to saddle seat connection that makes the noise.
Maybe 29 inch wheels would help... 😛
if your seat post is a micro adjust with 2 bolts securing the rails check all those parts...it happened to me once when i went over a pot hole....i thought it was the dry seat rails and didnt check it until i took it to llandegla a few weeks later...it turned out one of the cylinder bolts had cracked and the whole assembly fell apart 2 miles into the red route, meaning i had to continue without a saddle and seatpost... 😯
The only time I had a noise like this was when the seat tube was cracking from the inside out. The seat post was well in the min insertion point but not much beyond the top tube/seat tube junction. Just saying.
