Why We Like the FormMount Stem Computer Mount

It can be tough to find a good mount for our GPS. That's why F3 Cycling created the FormMount Stem Computer Mount. It's a secure and stable modular mounting system for GPS computers, lights, and cameras, and it's ideal for everything from racing to training and recreational riding. The FormMount's direct stem integration features adjustable arms that provide the ability to fit nearly any four-bolt stem in five various mounting positions, and it's compatible with Garmin, Wahoo, Hammerhead Karoo, and Sigma Sport.

It's worth the installation woes

I've put it through the wringer

The other reviews are not wrong - installation can be frustrating. Learn from us and use the Bridgetool from the start. Once it's installed, though, it's all angels, sunshine, and rainbows. It's a rock solid mount for your head unit plus a great bottom mount option for a light or GoPro. Note: You can't adjust the angle of the mount. Whatever the angle of your stem, that's where your Wahoo will point. Something to keep in mind if your stem is +17deg and you're aero-conscious. Not a concern for me personally, as my spare tire is a bigger source of drag. Get it, follow the instructions, use the Bridgetool, and you'll love it.

Tricky Installation

I returned this product before using it
True to size

Watched the YouTube instructional video and used the Bridgetool. Unfortunately when I tightened the stem bolts to spec the clamp arms still moved a bit so it’s a little off center. Took me about 30 minutes to install. I travel with my bike a lot using a bike bag. Having to re-install this mount every time I take my handlebars off is just not worth it for me. Still looking for an outfront mount solution for my Enve bar with Salsa stem setup...

Impossible to install level

I've used it once or twice and have initial impressions

Needed a stem mount since my GRX in-line brake levers took all the handlebar space, it has great adjustability, but plan to waste hours trying to get it level, even with the bridge device clamped down. It drove my OCD crazy, I removed it, there are better cheaper options out there.

Hi Jeffery, Mike from F3 here. First off, I’m sorry to hear about your negative experience with our product. The very nature of FormMount’s direct stem integration does require a bit time to get it just right, and using our BridgeTool as directed will absolutely ensure a perfectly level position. We do have helpful install videos in the user guides link of website. I sincerely hope you’ll give it another shot. We are new to the Competitive Cyclist community, so you happen to be the first review. That said, #f3cycling on Instagram has hundreds of customer posted pics proudly showing off FormMount. As they say, a picture is worth a thousand words.

F3 should employ tapered slotted sleeves to resolve the center alignment issue. It would be easy to design this integral to future designs. Definitely interested in the product, but reviews have me reluctant.


Does it come with all modules necessary to under mount a gopro, or a light?
