I think I need 20/25mm offset, infinite adjust, 25.8mm seatpost, but that's not turning up anything. What should I be looking for?
First decide what size it really is, because 0.2 mm is a big difference with seatpins and 25.8 is weird - did you mean 26.8 or maybe 28.6 mm? Those are sizes I've heard of. If it's an uncommon size you might want to consider using a smaller common size like 25.4 or 27.2 with a shim, for wider choice. I like
these they adjust easily with no notchiness and don't move once they're tightened, also a decent amount of layback (I usually slam my saddles back).
P.S. I just checked, that style seatpost is available in 25.8 mm like
