This adapter kit bolts directly to all base bars with the Profile Design A2A riser system. It allows you to adjust the angle of the aero bars from 15-30 degrees (replaces PD A2A angled riser).

Taller stack height is possible with additional spacers and longer bolts (not included).

Kit includes the following:

• Option of Standard adjustable angled riser OR Extended angled riser(select option below)
• 2x base bar adapter spacers (see note below)
• 2x adjustable angled risers (15ᴼ to 30ᴼ adjustment)
• Base bar bolts (4x 50mm)
• 4x M6 nuts
• Base bar NOT included

IMPORTANT: The adapter spacers are 3D printed in glass filled nylon (GFPA12), a very hard and durable polymer that contains glass fibre threads. Being polymer, the spacers may compress slightly over time, especially in hot conditions. Please check and re-torque the mounting bolts regularly to ensure a secure attachment
