I have a Time Monolink stem, which has a unique way of being mounted. Instead of having bolts go through the faceplate and into the stem, the bolts are in the stem, go through the faceplate, and are secured with caps. See below:
Consequently, setting up an integrated computer mount is not obvious. I have been using the Garmin bar mount, but would prefer something more streamlined. Does anyone have any genius ideas on how to get a mount on this stem?
Wondering if instead of the capping nuts, you could have a small connecting piece that is threaded from both sides (and probably have external flat sides to be tightened for the stem). You’d screw that on instead of the buts, and then bolt the computer mount into it. Might need to get a workshop to make yo something like that.
I bought this brand, has held up well.

Please do not drill holes into stems / faceplates that are not designed to be there. You are just begging for an emergency trip to the dentist, at a minimum, as well as endangering other riders around you.
A creative solution might be to get a stem plate 3D printed to take a Garmin mount. I don’t know if I’d trust 3D printed components though. I had a 3D printed TT Elbow Cup that failed but that might just be a one of failure (its only n = 1 )
There are options out there from titanium to structural composites, but any of them will be at least a partial crap shoot unless you go with an engineer driven designer who understands the function and requirements for these parts. Most of this stuff has to be rigorously tested for strength and durability before sale, which means I would NEVER trust a part of this importance without a LOT of design & analysis.
The standoff idea is the best of any suggested from a cost and risk standpoint and is the only thing I would try if it was my bike. That said, picking a proper standoff with enough strength is super important as well and should not be done lightly. In the end, I’d personally stick with a bar mount.
