Somewhere on Facebook they published a stiffness test comparing to an heavier mcfk
McFk: 84.5g / 8.16mm deflection(60.1 N/mm) —> Stw 711n/mm/kg
GrigioCarbono: 55.5g / 8.18mm deflection (60N/mm) —> Stw 1081N/mm/kg

Yes it doesn’t have a front plate you can remove (how many times /year do you change bars via the front plate?) but unless we doubt on the test authenticity, 50% better are is amazing.

Edit: dream bike shop did publish / shared the test

I'm curious how could i mount aero road bar on that stem.
insert bar from drop end to top of the hood area without shifter might be possible but the flat wing part?

Hum Image very valid point.... request them to bond you aero bar to the stem cutting the clamp part Image

Personally i would like to see more different stem angles (-8, -10 & -12) and also half increments like 105, 115, 125mm aso.
Now it's always -6 degree and -17 degree (a bit too radical)!
Almost all new esoteric bars are 80mm reach/ 130mm drop, i mean come on, what is the meaning!?
Where are the 70/75mm reach and 125mm drop bars?

I like more narrow drops, then i can mount the bars lower and still have a nice fit in the drop zone.

Horrible graphics, but nice weight.

I've found that open face stems where one side of the clamp wraps around more than 180 degrees (think MCFK or Ritchey WCS 260 stems) can't be used with some non-aero bars. I bought a Ritchey WCS260 to use with some Syntace Racelite carbon bars, but found that I couldn't fit the bars to the stem because the slightly oval shape of the bar each side of the centre meant that the stem couldn't be slid along from the side to the clamp area at the centre.

What's the price? The web site doesn't even list the product.

Horrible is an understatement! 1995 wants its graphics back.

Those graphics are awful! Although, it's a lightweight carbon stem, most WWs would probably sand it anyway :D.

They are working in a version with a front plate for aero bars.

Luckily seems other versions do exist and you will be able to remove the stickers

It's not prettiest but not bad at all if you compare to other lightweight stems.Font look okey on those C36's posted pics.

Can’t say that a lot of light stems are pretty:

McFk clamping section is big and never really integrate well to modern bikes

Ax, either one need viagra the other is  « ok »

This one is probably the prettiest
