Seat pole

Clean the grease of the post, try using chalk. It work for me on the MTB.

Is this due to
a) the chromed finish
b) a film of grease between the post and the clamp
c) me being 110kg
0r d) all of the above.

Any suggestions on how to make it non-slip?

You want a *very* thin film of grease so that the seatpost doesn't become
permanently attached. I know it sounds obvious, but have you tried
tightening the clamp just a touch? Otherwise it's possible that the
seatpost is slightly undersized. If there's too much grease try wiping it
off around where it should be clamped, leaving a super thin smear.

That's essentially what I have done. I cleaned the grease off the
post, cleaned around the inside of the seat tube to around 1inch
from the top, then replaced the post, and tightened. Fingers
crossed that i will have fixed it. We shall see...

If that doesn't work try a shim made out of an old aluminium can.

The only thing to be wary of with that is when you have a steel frame and
steel seatpost. Putting a thin layer of aluminium between the two sets you
up for all manner of dissimilar metals corrosion that would not otherwise
have been an issue. I'm prepared to be corrected by anyone with a background
in metallurgy or course.

How many people use steel seatposts though?

I've never seen this happen, whether this is 'cause of grease use or the
thin layer of plastic which is on the inside of alu cans I can't say.

I had touble with seat post slipping (similar weight), until I replaced the quick release seat post clamp with a fixed (non-quick release) seat post clamp

My post clamp is a fixed one. I'm tightening it as much as I can
(I'm a little worried about stripping it if I go much tighter!!).

Maybe the solution is another seat post, one that grips better!!
