Review on 🚲 F3 Cycling Bike Stem Computer Mount Holder Stand - Stable, Versatile, Compatible with GPS (Garmin, Wahoo, Sigma, Hammerhead), Cameras, and Lights by Shawn Xayamonty

This product works well enough for a small computer. It takes a bit of work to get everything aligned, but when it's done everything works pretty well. I would only recommend this product for smaller computers and would not recommend adding a Go Pro accessory mount. Here are some of the problems I've encountered. I got tired of contacting F3 twice and got no response: Basic: 1.) I installed the GoPro camera/light component and adjusted the stand to the extreme position to fit my Garmin 1030. I installed the Cygolite 1100 with the GoPro adapter. The light slides into a Gopro adapter that screws onto the F3 camera/light component. To install the light, push the rod until the latch clicks to secure the light. A heavy push is required, something you'd expect from a precision fit, but nothing out of the ordinary. I have used this mount on the K-Edge with no problems. When I first installed this rig on the formwork, as I pushed the lantern back to put it on, the cradle slid into the stem. I checked the mounting screws, everything is tight. I disassembled the unit and inspected to find that small ribs in the camera/flash component were slightly "bare" as a result of this movement. I reassembled it and tried again, everything was tightened well. And it slides on, now more easily, to the point where the tote slides back and forth over your arm with little effort. It goes so far that I can no longer use it reliably. I'm thinking of epoxy connecting the arms to the camera component. I think the fin protrusion could have been increased a bit to prevent this. Moderate: 2.) I noticed that when attaching the Garmin to the formwork (with the Garmin insert of course) the fit is very tight. I really had to force the rotation to bring him home. It was a bit easier the second time, but still requires a lot of effort. I removed the harmines and examined the tabs to find any plastic deformation on the side braces or crests, the edges of the crests were rounded making the crests look larger. I compared the formwork insert to the Garmin mount and found that the side members that grip the shells are significantly larger on the formwork. They keep sticking out. In addition, the plastic used to insert the formwork is more rigid/hard. These two together led to this event. Each time I've installed Garmin, the tabs have warped a bit. To fix this I cut the formwork panels to Garmin size. At the same time, the effort required was significantly reduced, but at the same time a form-fitting click and reliable locking was generated. I also noticed that the smaller feature no longer distorts the Garmin tabs. I have confirmed this by installing another Garmin with no damage to the cleats. Minor/Subjective: 3.) It would be nice if the camera component had a built in Gopro screw nut like the Lezyne version. The molded notch that prevents the nut from turning doesn't do its job well. Not much tightening force is required to loosen the nut, the nut simply rotates in the recess. Two tools are required for tightening: a hex wrench and a socket head. The levers feel quite heavy, but the installed Garmin 1030 flexes a lot when the stand is fully extended. It appears that much of this vertical flexing is due to the curvature of the cradle relative to the arms. In addition, the lateral/torsional stiffness is even worse. While this is less of a problem, it's noticeable because the arms can rotate in the stand even when tightened. I'm not sure what can be done here as the ability to spin is necessary to allow for different landings. Maybe it helps if the bassinet is somehow pulled onto the hands with more force or more friction? Torsional/lateral stiffness became a bigger issue as the low mounted light created more moment in the system. I've noticed that when turning the lights on and off, the whole assembly flexes a bit. I also noticed that the system on the Garmin 1030 and Cygolite 1100 flexed a lot when the bike was shaking. I understand that a bridge tool can be used to increase rigidity, but I would prefer a more elegant solution. Using a bridge tool while driving seems at odds with the streamlined shape of the mount.
