Of all carbon stems, this one is definitely the best looking one in my opinion. Finish looks smooth. I'm not so sure about the faceplate system. I feel its inner surface should be rougher to reduce bolt torque, although the carbon clamp surface is probably rough enough to offer sufficient resistance against bar slip. It would be a good idea for MCFK to offer aftermarket anodized faceplates.

@Beebee30: The AX Rigid, their stem for Ø31.8 bars, goes to 120mm btw. Though especially when you ride 130mm stems, like myself, or even longer, few carbon stem are an option. Ritchey offers their SuperLogic Carbon stem in 130mm. Then again, my preference goes out to an aluminum stem.

That's a nice looking stem! With the carbon section coming more than half way round the bar, does the bar 'pop' into the stem (with a little flexing) ?

I would question stiffness if the bars just popped in.

That is a good question. How do you get bars into the stem? I'm with Wcl4, if the clamp area flexes a little so you can get the bars in, I would question the strength as well.

Maybe you insert the bars at a skinner section and then just slide the stem over?

It will slide by the side, like Ritchey C260, I guess.

Perhaps visuals offer a better perspective than words:

Looks really nice, and the weight is great, but the price is redonculous. Also, at that price the logo should be applied using a better process than just a sticker.


I think that only a sticker is a good option, since there are other people like me that removes all logos from componentes.

Their stickers are pretty high quality. The one on my saddle looks brand new even after a year of riding on it.

I'm thinking that try to make a BarStem combo again with this new stem.

I've been waiting such this 17 degree stem by fully carbon made for a long time.
If I use this for BarStem, I can use carbon handle and stem in durable.

I've already made a BarStem with Calfee's original stem though I've not been satisfied with its neck.

Then, I also think it's better to use the same method as they use in handle clamp to the steering tube clamping part... I like this way and idea.

MCKF might even be willing to do something like that.

As far as fit goes with the MCFK stem, I asked Martin (by e-mail) whether or not my Zipp Vuka Spint bar (with flat aero section) would be compatible with his stem and he assured me that there would not be a problem. (Starbike is actually taking orders as I am sure are others.)

any real world feedback on how the MCFK stem holds up the real world rigours of hard riding, anyone? :)

slippage issues?

and how does it compare with the AX rigid...now both available in 12cm btw...

...but AX 590 euros vs. MCFK 299 euros

bought one about a month ago to use for a special event (a hill climb / race up an 8-10% grade for ~6 miles).

i went with a 110 because it was the longest available, although i typically ride a 140.

i rode it quite hard--32-minute all-out effort. it was 5 w/kg average with some spikes (e.g. a "sprint" at the end). no slippage at all. build quality is very nice. i could not discern any flex, but by nature of this type of ride i wasn't doing a true sprint where i am pulling very hard on the bars and shoving the bike from side-to-side.

weight was right at whatever was claimed.

removed it after this race....i'll install it again for the next time weight really matters in a race (for me).

for reference, i prefer to ride the PRO vibe 7s puzzle clamp stem on my race bikes.
