NBD , building a touring setup for this summer
from Amazon- Vincita Lightweight Specialized Quick Release Seat Post Clamp for Carrier Fixation (27.2 mm/31.8mm)
You have to buy them specifically to seat post size in mm. Just search for bicycle seat post clamp and your seat post size. You will find 2 types. Some are simply to hold the seat post up and do not have the extra mounting points for a rack, so be aware.
