Framebuilders Thinking about a custom frame? Lugged vs Fillet Brazed. Different Frame materials? Newvex or Pacenti Lugs? why get a custom Road, Mountain, or Track Frame? Got a question about framebuilding? Lets discuss framebuilding at it's finest.

Big Ass Build

Since most of the world is in quarantine, I thought I'd use the time to put together a build for a customer who is 6' 8". He's a tall dude for sure. I wanted to put up a list of tubing that I've chosen for the build to see what y'all think. For what it's worth, he's 210lbs and he's pretty powerful as well. Will this tubing selection be adequate for someone of his stature?

TT: Deda Zero 31.7mm 6x4x6
DT: Zona 35mm 8x5x8
HT: Paragon 230mm
ST: 31.7 Columbus Life 8x5
SS: Deda Zero 16mm
CS: Deda Zero 24mm Oval/Round

Thanks in advance.

Brandon

I'm 6'4" and plus 230#. My concerns would be the top tube only because of ease of denting? and the head tube/steerer length. Unless he wants to have a large seat top to handle bar height distance he will probably need a fork with a 350mm stem and longer head tube to limit the steerer spacers. At 6'4" my handle bars are 3-4 inches below the top of my seat with an uncut 300mm steerer tube. There are carbon forks with a 350mm steerer out there.

You can buy 44mm head tube material in 2 foot lengths from Nove, Bike Fab etc.

Thanks for the reply. Good thought about the TT. I think I'll change it up. This bike isn't going to be a Sunday special, so he's looking for a fairly aggressive design. I was going to use an Enve fork since they have steerer tubes of 350mm so I'm good there. Regarding the HT, I really like the look of the Paragon. They are nice and clean.

I agree with ws's suggestion of a thicker walled TT. Not just for dent resistance. I've long time felt that a frame feels best with somewhat balanced tube walls. A single step different (as is common with a TT being .1mm thinner walls often) sure. But two or three steps thinner seems out of step to me.

Consider allowing for more then typical (for intended use) tire clearances as a really tall or big rider needs more air between the rim and road.

Back in my Cyclery North time I built one of the 72 and 74cm frames we did that year. I wish I had the knowledge then that I have now. The frames would have been quite different. Here's a shot of the one I made. Andy

Now that is a big frame. Thanks Andy, what you guys mention totally makes sense. I switched it out with a 7x5x7.

Your tube selection is on the thin side of average. Should be okay unless your friend is a masher. If that's the case moving to thicker CS's would be my first move.

Thanks Nessism.

He does have some big power. Should I go 969 on the DT? The CS I chose are 1.0 and .7 and 30.5 x 15.7mm; not thick enough?

That sounds pretty beefy. Zero tubing tends to be pretty thin thus my assumption that they were thinner/lighter.

Roger that. Yes I've noticed that as well lately the more I've been using it.
