I see. Columbus does nice R800 bend seat tubes in 550mm. They might have started making them longer now. I had one made custom for my MTB - 600mm I think. Stayer ordered 10 directly from Columbus. Maybe get in touch with Sam and ask if he will sell you one.

Exactly what I'm planning to use, the seattube in the second image is a ZON113550110F. If anything it's a bit long actually. Can't cut the top because of the external butting, so the bend already is a tad lower than it'd ideally be. But I also need to take into account the maximum extension of the PNW Rainier.

Cool beans

Sorry for not keeping up and just shooting wild with suggestions on an uninformed basis

No worries, it's reaffirming to see that my ideas aren't completely outlandish. My frame building experience is limited to fidgeting in CAD and sending a list of tubes and measurements to Jaap.

a nimble frame that weighs 60kg

Sounds heavy for a frame.

Need to level the saddle, shorten the outers, and trim the cables. The dynamo lights are great, wouldn’t go for a Shimano hub on a bike I ride in anger but for a commuting bike it’s perfect.

Too on the nose?

The fact that no one has an opinion on this confirms that it might be a bit tame, back to the drawing table. Would like something that ties them together without just spraying them the same colour. Although I could get one of those blue SIDs and go for identical paint schemes.

Also, with the graveler almost finished I need to re-organise my Kelleranteil to make space for more bikes. It's become a right mess.

I could get one of those blue SIDs

Could and should

Ordered this stem in 80mm for the graveler, not sure if I like but at least it’s not as boring as a Kalloy Uno.

I like it. Looks like a deda Superzero

Looks good!

Project cellar reorganization is in full force, ordered a big shelving unit to sort out all of the boxes. Just need to figure out how to have a bike left of the Kona standing upright, has anyone tried those Clug thingies?

The graveler is supposed to be finished, should be making its way to me via multiple friends sometime soon. Can't wait.

The mountainbike is nearing something that might be a final design, or at least geo and tubing wise. Lots of small choices to be made in terms of cable routing and zits. And I need to check if I have the fork A2C sussed out, something looks off but it might just be the model I'm using as a mockup.

68 degree headtube, 74 degree effective seattube, 425mm chainstays, 2.5" clearance.

Clearance probably via little cutouts like this, or maybe dimples. That's up to the 'fabricant artisanal'.

Checked @Hulsroy 's model against the actual forks, made some modifications and I think it's good enough now.

Looks nice dude

I'm considering going tapered because it opens up the triangle a bit and I like the drop-in nature instead of requiring brute force to install and remove a headset.

And the increased cost of a tapered head tube is offset by being able to use a cheap headset because you barely see it anyway. Or so I told myself before I bought a CK DropSet for the gravel bike.

Really liking those renders. What software do you use for these?

Fusion360!

Look awesome! I generally dont like the look of a tapered ht. But really works!
