Argon 18 Krypton/Krypton Pro or Open Min.D.?

I’m now in the market for a new all road/endurance road bike (not a gravel bike). As an older and shorter rider, I’m researching bikes with a shorter reach (~365 or shorter) and taller stack (~525 or taller).

Two bikes that popped up in my search were the Argon 18 Krypton/Krypton Pro and the Open Min.D. I’m somewhat familiar with the brands, but not these models. Both have some unusual features. The Krypton line has a “3D” system that actually raises the top headset bearing to maintain stiffness while increasing stack height. The Open Min.D. has a seat mast with a proprietary top cap. There are other differences, but both seem to fit the bill.

Probably a long shot, but does anybody have any experience with either model?

Thanks in advance!

I can’t tell you how any of these two ride, but I see Open frames and bikes discounted to real bargain prices, like 1365 € for a Min.D. frameset. If that is your kind of product, I don’t think you can do much wrong at this price.

make sure the Open framesets are UDH compatible or your choices for drivetrain will be very limited. I see the heavily discounted ones are not.

I expect that a new version the min.d may be on the way (many styles out of stock on the open webpage and deep discounts elsewhere).

I expect the min.d 2.0 will have an integrated front end (like the recently released up 2.0) which is a pro or a con depending on perspective and UDH which I view as nice but not a necessity particularly for road.

Is there any reason you are married to carbon? This seems like a reasonable time to consider custom steel or titanium as the bike can be built to fit YOU rather than trying to adapt something off the shelf.

I love the Argon Krypton Pro. I had a Krypton GF which was outstanding, but some physical stuff forced me to a very different frame.

I love my new bike (they’re a bit like children in that way, no?), but I do long for the Krypton from time to time.

Where do you find these discounts? I can’t find them.

I have a 2021 Argon 18 Krypton Pro and love it. It was a bit of a lark based on a nice review on the Grand Fondo Magazine Website. But I have been very happy with it. I ride about 120 miles a week and have not changed a thing on it to date. Every now and again, I think about the possibility of a new bike. But I honestly cannot think of anything that would be that much better on a new bike. I may some time point finally get around to swapping out the HED Vanquish wheels for a different wheelset. But that will be more of a want than a need. I’ve been happy with it and I like that I don’t see too many other Argon 18s in the Metro DC area.

Heavily limited only if you want Sram XPLR or possibly some future Sram road groupset. Not for Shimano or Campagnolo. And how many people do really swap groupsets?

The Krypton is a great choice when you need shorter reach and taller stack. Very fit adjustable. Solid bike. The Pro is a lighter frame.

I have a 2022 Krypton GF that I really enjoy. A decent amount of tire clearance and a fit that works great for me.

Current timeline is late '26 / early '27, so not for a while yet.

I’ve just ordered a MIN.D in ‘ready-to-paint’.
