Looks like you can run

mdadm -E /dev/sda1

or similar against one of the devices in the array. It will print the superblock and lists the chunk size there. Note that the switch is -E, not -e.

See the third grey section here

EDIT: See here here and here on chunk size in RAID1

Corrected switch to -E as per quoted link. Clarification of this was added to prevent a 'minor' edit, and can be removed if desired.
