Yep Steve and Peter North, formerly of Mad Fiber wheels spent a lot of time with learning about joining and wrapping the tubes.

Big differences I think are that (1) Nick has been building these frames for a long, long time so he has that experience edge and (2) Nick now produces his own tubesets to his specs whereas Hampsten (afaik) is still using Enve produced tubesets.

Altum was nice but the front end didn’t seem to be very stiff. I could feet it flex out of the saddle and I am no masher.

Maybe I am resigned to think that all bikes with head tubes over 200mm allow flex, and the steerer is the main culprit. Unless the steerer is reinforced it’s going to flex (at that long of a length). My five year old TCR with a 185mm heat tube (and 15mm hs cap and 30mm spacers) is solid as a rock. No shimmy, no flex.

The Altum has a brand name but it’s just a mold frame coming out of Taiwan (which I have no issue with). Lots of similar frames coming out of Giant factory costing a lot less. Custom Parlee; ~$9k. ISYN!

Need to investigate tube to tube custom on a budget.

For a tall rider who really wants stiff, if I were building for you, I'd probably recommend a disc road build based around a Columbus or Enve gravel fork. They have about 15mm extra axle-to-crown, which will allow that much more to come off of the head tube. Plus, since they're built for gravel riding, they're made beefier than the comparable road forks. Pair that with a 44mm head tube, 2" down tube, and 1.5" sloping top tube and I'd all but guarantee you wouldn't notice any flex.

Agree on the 44mm HT. There must be road disc fork with some kind of reinforced steerer or more taper.

Geez, I wouldn't come to that conclusion on headtube length. As was explained to me, one of the reasons Dario Pegoretti when with extended headtube/dropped top tubes on his frame is his belief that the extended headtube did a better job of supporting the steerer tube. But I'm not sure i'd put the suspicion on the steerer tube either. My Peg is over 22cm headtube with straight 1 1/8 carbon steerer on the fork and its not soft or flexy. Same for my Hampsten carbon with tapered fork, etc., etc. What about the handlebars or stem or flex in the wheels on the bikes your are testing?

I'm 6'3" 215 on an average day, former college heavy weight 8 rower, and I'm not as strong now as I was then but all my bikes have 20cm + headtubes and 300-310mm steerer tubes of various sorts - steel, carbon, tapered carbon I can't say that I've even experience noticeable flex from the headtubes or steerer. Not saying it doesn't happen but its not a given on a large bike.

I have no idea how all the factory bikes you are trying are configured but I'd give consideration that there may be more to front end flex/softness than the suspects you're keyed into.

BTW Crumpton, Hampsten and I believe Landshark are all tube to tube construction if that helps. Maybe call some of these guys up and have a chat. They're all straight shooters.

So, I know Hern's work was mentioned before, and I recalled he made a rather large frame sometime this past fall, and I found some pictures of it on his Instagram feed. If memory serves, it's the biggest he's ever built.

Here's the finished product: https://www.instagram.com/p/BmW8W8hheko/

Can't go wrong with any of the above folks mentioned.

Tier one SMEs with fit and frames, and simply nice and good peeps
