It’s about a year old, low and gentle mileage. It’s been fine and kept clean etc.
Yesterday saw it at Dalby where it was OK for the first part of the ride, but then it started to feel like it wasn’t extending fully. It turns out it was extending fully, but the top ~3cm would then go back when sat on (and it came back up when unweighted without using the lever). So it wasn’t dropping, just behaving as it the top 3cm was a (very weak) suspension post.
No amount of faffing with cable tension would make any difference to it – it drops and extends fine, but when sat on the top 3cm disappears and re-appears when unweighted. Amazing how such a small height difference strains your leg muscles!
At various stages there were a few creaking noises but these could have been saddle rails I guess. At no stage did the post move in the frame, and it’s all clamped up to the correct torque.
Anyone else had this?
