MCFK Stems and Seatposts

[NONN]

Does anyone have experience with MCFK components (e.g., stem, bars, seatposts)? Are they trouble free?

Considering these for a new build (road bike).


Thanks

Boutique brand. Expensive. But people buy for lightweight components.
I had a stem and a seatpost from them for my Cannondale. Built it to 12.5 lb!
Cant fault them!

Thanks for your feedback - any slip issues with the bar and stem?

make sure seatpost will work. there is an area on their posts you must clamp within. can't be outside that area as the rest isn't reinforced to save weight, if i recall correctly. this was on their offset post. i returned it once i saw that.

No issues whatsoever. I did use Carbon anti-seize made by Park Tools.
But since you are in the price realm of MCFK, I would recommend Darimo. Even more lightweight and just a bit more expensive.

what cinema says about the seat post..(double check) because the clamping area is reinforced so you need to stay within. I have a stem and it's performed very well, I did have some slippage early on but eventually got it to hold with plenty of carbon paste (gritty kind)

I was really impressed with the build quality the last time I built a bike up with them. Unfortunately, the build was for a customer, so I can't report on long term reliability.

I've had zero issues with the two MFCK seatposts I have. However, there are different lengths, and to second cinema, you have to make sure you're within the working range of the length. if you have one of the posts, you'll can clearly see where that is.

As for the stem, I had to get one warrantied due to it's cracking at the clamping assembly (which is completely cool). I got the new one, inserted my bars, scraped the bars, got bummed out and bought a different stem and new bars. They sure look cool, but everything works out for a reason. Also, as long as you use assembly paste, you're not going to get any slippage.

MCFK is light and cool, and it's the closest to getting a McFu¢k sticker on a part as you're going to get. So get McFu¢ked.

Saw the Darimo handlebar, stem and seatpost at a LBS and they are quite impressive.

I owned both on my Moots Vamoots RSL.

Very light and worked just fine.

Just know that you will need to remove bar take and brake/shift lever to install the stem. But it's kind of set and forget.

I had a similar experience. 3 posts all without issue, and 2 stems both cracked at the clamp. Warranty was handled without issue both times.

Look good, but I’ll choose some other stem over these.

Very helpful insight - much appreciated

If was buying I would go MCFK stem for aesthetics and Darimo seat post as there is more layback available...

I ran MCFK bars and posts for years on MTB and Road - zero issues........bombproof!

Still have a setback mcfk post. Had it for years, works flawlessly. If you're looking for one, you'll have to go used. Their newer design (which is what's available retail) are much heavier than the old ones.

I've also used their stems over the years and they work well. If I was going for a seatpost today, I'd go with Darimo. The stem you could go either way, depending on which stem works with your bars. The mcfk stem can be slid over aero bars to the clamping area (round), I'm not sure the darimo can do that based on its design.

I have this Woodman on my Endpoint gravel bike. I've certainly abused it on some rough trails and hit the saddle pretty hard. It's in the same weight category and way less money. I'm very impressed with the quality and durability.

This stem is also fantastic for weight/cost.

That's what I use now. If you want to drop another 15-20 grams, you'll need to pay up for the carbon ones.

As for the woodman post - same deal. If you want to get around 100 grams or less, this won't do it. The many of the darimo posts are coming in under 100 grams and I have one on one of my bikes and it has been trouble free.

It all comes down to how much you're willing to spend and how much weight you want to drop.

I have two of the stems in 90mm length on my road and gravel bike. No issues with the Easton E100 bars and carbon paste.The stack height is tall, but if it works aesthetically, it's a good stem.

I have 1 MCFK seat mast topper and 4 of the newer offset seatposts in various diameters on other bikes. They've been absolutely problem free.

Exactly, but for the dollar/gram difference I'd carefully look elsewhere on the bike to drop weight first. Many cheaper ways and I'd save MCFK or similar pricing for bikes that are already decked out with Red/Dura Ace, carbon frame/fork, lighter wheels, lighter skewers (usually a cheap swap) and probably things I'm forgetting. If we're talking about an steel/titanium bike or something with Ultegra or Force the Woodman or Kalloy are nice ways to drop grams keeping in line with the rest of the parts. Something like an English steel bike would be the exception as those are no holds barred bikes regardless of material. I think I'm making sense at least in my own head.

I have MCFK seatposts on 2 bikes and couldn't imagine using anything else.

Great to know - seems based on the responses that setup (torque, etc.) is critical. Happy to hear so far no reports of failure - I've been using ENVE stuff, which is problem free, but dig the look of the Mcfk stuff.

Nice! Proposed use will be rough county roads.
