Description

The newly designed 5kg (11lb) counterweight (CW) uses compression ring to lock the CW onto a CW shaft. Comparing to traditional "point contact" locking mechanism via a locking screw and a pin, the compression ring provides more secure locking method through distributed surface contact.
