Wingspan Extenders and Wingspan Extenders XL Installation Guide
Important Note: Wingspan uses M6 hardware by default; some aerobars/brackets use M5. Match the bolt size to your bracket’s threads—never force/cross-thread.
Wingspan changes pad position (fore/aft/lateral/angle) but does not add tilt—use Angled Spacers if you need arm-cup tilt.
Step 1 - Remove any arm cups from the arm cup mounting brackets on your cockpit.
Step 2 - Orient the Wingspan plates in the desired mount position: forward, rearward, side to side, or angled. Using the slotted holes on the Wingspan Extenders, mount the Wingspan Extenders to your arm cup mounting brackets using the supplied M6 x 11mm bolts.
- Note: You can also use M5 bolts to mount the Wingspan Extender if required for your base bar.
Step 3 - Mount your arm cups to the Wingspan Extenders using the M6 x 10mm bolts.
- Note: If mounting TriRig Scoops to your Wingspan extenders you only need 2 bolts per arm cup for proper installation.
Step 4: Torque: 5–6 Nm (Wingspan → bracket), 4–5 Nm (arm cup → Wingspan), unless your bracket/cup specifies otherwise.
We do not recommend using Wingspan or Wingspan XL on the Trek Speed Concept aerobar due to its smaller M4 threads
