Steerer tube mount for Wahoo Elemnt Bolt

cults3d

I recently acquired a Wahoo Elemnt Bolt to replace an old Garmin Edge 500, which had become quirky over time. Upon examining the mount, I discovered that despite its resemblance to a Garmin mount, it's rotated 90 degrees. Having relied on Bryce's Garmin stem mount in the past, he kindly accommodated me by rotating the mount, but I soon realized the dimensions were slightly different, resulting in a tight fit for my Wahoo. To resolve this issue, I redesigned the mount. Additionally, I noticed a request for a Wahoo mount compatible with the Bontrager Blendr mount, so I adapted this basic design to work seamlessly with both types of mounts. This particular mount is designed specifically for steerer tube installation and replaces a standard 1 1/8" headset spacer to secure the Wahoo over the stem. I've also included an alternative version that substitutes the stem cap and a spacer. To assemble it, you'll need a flat head M6 screw measuring between 25-35 mm. The flat head distributes stress more evenly across the cap's surface, reducing the likelihood of breakage compared to a standard socket head, which concentrates stress on one point and may cause the cap to crack. However, I must caution that I've printed this design in PETG, and when I used it on my bike, it didn't fail immediately. Nevertheless, the entire curved top cap surface simply sank down, rendering it unusable. Based on this experience, I strongly advise sticking with a conventional aluminum top cap for added durability. I've successfully printed and used this design with a standard aluminum top cap on my trail bike, and it's been working flawlessly.
