Glad that’s sorted for you pre-Thailand Matt.
I was wondering if tension and or proofide had played a part at all?
Not sure of the cause. I was pleasantly bubbling along on Westray an island of Orkney mainland and suddenly things definitely didn't feel right saddle wise.
As I dismounted the tension bolt clip fell out onto the sand. The bolt was nowhere to be seen. Very strange.
I spent half an hour trying to work out what happened when. And searching the ground.
I had a ferry to catch back to Kirkwall so didn't spend as long as I would have liked looking around.
With no tension, I was sitting on the rails; not pleasant.it was a Friday, so popped into the LBS on Saturday. They said they could bodge it to get me through my short tour and that's what they did.
Excellent service.
Back to your question; I do proof the saddle on a regular basis and the tension looked ok before I set off.
So maybe it was old age. I must have used it for 9+ years on all my tours. Not sure of their ' life'.
Maybe I had over tensioned it?
