2 bolt threadless stem?

Saw that Thomson is now offering a new “G2” (gravel?) threadless stem…an update of their X2 stem. I have been on the lookout for a 2 bolt threadless stem that would make break down/build up of my Ritchey Breakaway that much easier, but have had little luck finding one. Any other options out there other than this $150+ new offering from Thomson?

Thanks

I've seen too many handlebars separate from the bike with 2 bolt stems to ever want to use a 2 bolt stem.

Unlike with single bolt stems (in which handlebar encircles the handlebar clamp and is pinched by the bolt) or 4 bolt stems, on a 2 bolt stem the handlebar will detach if one of the bolts breaks. I've seen multiple cases of this happening

My 2 bolt Thomson slippped holding the bar, but it was not this new gravel version. I’m all for saving time and always looking for efficiency gains but two bolts on a stem isn’t one of them…a ratchet makes short work of this.

I rarely break bike parts, but the original X2 was one of them. I didnt get hurt, but man, it spooked me to hear a faceplate crack while riding.

In spite of me thinking these are beautiful looking stems, I would never ride a two-bolt Thomson again, redesign or not!

Pro vibe stem with the puzzle faceplate is two bolt- I’ve used them a bit and never had issues with this design.

The only 2 bolt faceplate threadless I've liked was the 3T Forgie (2x M5 faceplate and 1x M6 @ steerer). Granted the aesthetics are a bit dated, but they can be had for cheap.

Great suggestions

Think I’ll see if I can snag one of those puzzle type stems
