WishBone: Light and Secure

WishBone is a lightweight handlebar mount for your Garmin Edge 500, 200, 800, 510 and 810. A forward mount positions your Garmin’s display within the critical “normal forward field of view” and reduces the distraction of rotating your head down to see your ride data. WishBone is the lightest and most secure of the ogee handlebar mounts at 13 grams (the OEM forward mount is 27 grams) and is suitable for mountain or road bike use.


The two arm mount is secured with two M4 by 12mm socket head screws and nuts (not included). Although not required, two o-rings can be installed for added security. Look for 5/8” inside diameter, 1/16” thickness (AS568-016) for increased friction between mount and handlebar. O-rings are typically found in the plumbing aisle of your local hardware store or online.


WishBone fits all 31.8 mm diameter handlebars and is carbon bar safe.


Assembly of Small Parts

Once you receive the WishBone printed part it is important to inspect all attachment features on the part. You may want to use a toothpick to clear out any residual “build material” (which will look like dust) that might have made it past the Shapeways technicians. Because of the precision and small size of the attachment features, it is necessary that all surfaces be clear of unwanted material for proper function of the part.


Important: Before you insert the nuts into the part (see image sequence above), you may need to clear out any loose or packed-in build material from the cavity that captures the nut. This can be done with a toothpick. Once inserted into the capture feature the nut should align with the screw hole on either side. If the nut and screw holes are not aligned you can remove the nut (with a toothpick) and inspect the feature for any loose debris that might be interfering with proper alignment.


Also inspect the eighth turn mount feature (where the Garmin locks on) for any residual build material. Typically this is not a problem, but there may be unwanted material packed-in around the locating features (protrusions left and right), accessible from opposite the mounting side.


Mounting Torque: Tighten the mounting screws just enough to secure the mount to the handle bar, do not over tighten. The force required to lock the mount in place is very small. Although the “strong and flexible” nylon material is extremely tough, it can fail if over stressed in the mounting process.
