Seat guts?

[manida]

I just ordered a cool hairpin saddle but I can already tell that the part where the seatpost inserts is gonna be way too large for the narrow seatpost Ive got.

Is there some sort of shim out there? What about replacement guts? Suggestions?

The central clamp can usually be swapped out. Check the one in your existing seat.
