Have we been able to see if the required faceplates fit other stems?

the faceplates for syntace stems come in 2 flavours - M5 bolt and M6 bolt. they are ~40mm c-c - i'll measure to the .00 mm this week as several folk are interested. also, they are l and r so width doesnt mater, the clamp for syntace stems is a 200 degree to main recepticle design. i cant advocate them being used on othe stems - i dont have a testing protocol - but if the c-c is the same i dont see why it wouldnt work, though frequent checking would be sensible! - ill bosh in some transfer screws and measure accurately this week and come back.

i'm tempted to go to syntace and see what they think of the whole concept - im just finishing off a second flat Strap Deck plate - workshop time is very limited at the moment! though they still require several set up steps while drilling the holes accurately, the transfer screw and punches have taken the need for painstaking measurement out of the equation.

its a damn shame getting moulds and cnc work is so expensive and has such big minimums! - dont give up the day job eh?

ok, quick update - the c-c for each side of all syntace stems I have is 40.15mm. if it helps that is more than for a Thomson stem. so - the Twinfix stems face plates may work with other stems, but you would have to measure up. FWIW, the face plates seem backward compatible with older style stems, and they can be had for relatively good prices.

I made another Strap Deck plate, using a different method for centring the holes required and it worked well, so I'll test the thing out and see how it goes.

I saw some Bontrager stems that looked similar to that Synace (much cheaper too)
Now that got me thinking if I could get the synace adaptor to fit.

I really like this...i have two bikepacking bikes, one gravel, one rigid mtb. I have measurwd the stems using my vernier calipers

Reilly is...
I/s 30.6mm
O/s 50.4mm
Bolt head 10.2mm
So assume c-c of 50.4 - 10.2 = 40.2 mm

Cube (spesh stem)
O/s 49.0mm
Bolt head 8.0mm
So assume c-c of 49.0 - 8.0 = 41.0 mm

With the stated c-c from DrJ, then the Reilly stem looks like it could be slightly modified with a dremel or needle file. Is the change from 41.0mm to 40.15mm going to be structurally too much? Will i die?

I'm sure have a Syntace stem somewhere (Cube branded). I'll look it out and check length etc.

Did syntace make stems for all the Cube bikes?

yeah, if you poke around on German eBay there are often cube, syntace - designed stems for sale. I reckon it would be surprising if the c-c was different, but then again, it remains a possibility....they are often cheaper than syntace and you can always remove decals w a bit of rubbing acetone...

for example https://www.ebay.de/itm/Cube-Stem-75mm- ... SwnfRcCRNy

be aware that some of the older style syntace stems used M6 bolts, where as only the flat force and megaforce do these days...the rest use M5.

id have to say I wouldn't recommend modifying the face plates. your well being relies on its integrity...
