• Convert Garmin quarter turn mount to fit Wahoo ELEMNT Bolt GPS Computer

    by  • June 28, 2017 • Cycling • 4 Comments

    Garmin has been making GPS cycle computers for a number of years and has almost become the de-facto market leader with their Edge range which utilise a quarter turn mount. Wahoo recently has upped their game with the newly released ELEMNT Bolt GPS computer, however it comes with Wahoo’s own mounting system.

    To make matters worse, there are not many 3rd party manufacturers using that mount, nor ‘cheap chinese’ suppliers yet. So if you happen to be in my position of requiring an additional mount (so I could add one to my Brompton), you have to pay out the big bucks.

    The cheapest stem/handlebar mount I found was £11.99 + £2P&P for 1 mount. Thats £14 for a tiny bit of plastic.

    On the surface though, the mounts between manufacturers look almost identical, however they are incompatible with each other… or so they are when new.

    I was able to source Garmin mounts much cheaper, a set of 2 official stem mounts from Wiggle.co.uk only cost £3.99. Once they arrived I set to work.

    The only real difference is that the inner plastic lip on the Garmin mount extends further, thus not allowing a Wahoo product to clip in. I took out a scalpel and cut less than 1mm from the lip, and as if by magic my Wahoo Bolt fitted perfectly! I found there was no wobble, or chance of the computer slipping out, it felt as secure as if it was in an official Wahoo mount. The only difference is that the computer gets inserted into the mount at 90 degrees in the Garmin mount now, rather than the regular 45 degrees of the Wahoo mount.

    The cut can be made to just one side of the Garmin mount, but you will have to slot in the Wahoo computer correctly each time. Instead you can cut the incision on both sides and it will be as if you own the official mount.

      Hello,
      I have just bought a Wahoo ELEMNT and think it’s amazing. I am currently obsessing about the mount because of having to “butcher” a Garmin mount (I’ve just bought one from Wiggle, too). I wondered whether you have had any issues with the Wahoo remaining stable in a mount that wasn’t designed for it? The Wahoo stem mount looks clumsy and wrong with its zip ties. Be interested to hear your thoughts.
      Also, I thought I’d alert you to these two links;

      Thanks.

        Yeah the Stem mount isn’t the prettiest, and mine looks just strange on a Brompton due to its slim handlebars.

        As I used a scalpel to do the conversion, the Garmin mount looks very neat and its hard to tell the difference. Its extremely secure (no issues using it offroad, gravel paths etc. so far)

        I will at some point update this article with some of the photos I took during the conversion as a reference.

      Does the adapted mount still hold a Garmin unit securely?

        Yep, a few months on it is still secure and I couldn’t tell the difference between it and the regular Wahoo mount. The only difference is having to insert it from just one side (as I haven’t cut the plastic on both sides).

        I have ridden offroad on poor quality hardpack gravel and my Wahoo Bolt didn’t budge one bit.
