I have borrowed a bike of my father and need to raise the seat post an inch or two..
I have removed the seat post clamp, sprayed some wd40 to try to loosen it and given it a wiggle. Yet to no avail.
I am wary of going too heavy handed on it for obvious reasons.
There is (what I think is) an aluminium collar. Is this a common issue with titanium frames? Any suggestions on how to loosen the bugger?
Thanks
