Kit includes:

1. Wider duck head
2. Mounting Arm for the Cross-Spoked duck head

Wider duck head for cross-spoked rims (a.k.a. laced rims) where spokes run out to the sides of the rim (like on modern BMW GS, Triumph Scrambler, Triumph Tiger, newer Honda Africa Twins, Ducati Multistrada, Moto Guzzi V85, etc.), where the side of the rim is thicker due to spoke placement and standard duck head will not fit. 

IMPORTANT: Standard duck head is not suitable for cross-spoked rims!

Always check for wear and tear on the duck head. If the duck head becomes scratched by damaged rims or sand on the rims, then it will start scratching also next rims.
