Advance Tandem Spreader BarsThe optional spreaders are a must for using a BIBPRO 3 with the BIBETA 6. An outstanding feature of all three spreader versions, Hard Hybrid, Soft Trim and Soft: cleanly running, covered reserve connection lines as a permanent part of the spreader. This saves not only a carabiner, but also the connection check before takeoff. KEY SPECS Spreaders Hard Hybrid 610g Spreaders Soft Trim 486g Spreaders Soft 374g Spreaders Light 282g
