Do not disagree.
6'3" 185pound Cat1 racer, wanted a stiff(!) bike for straight up, straight down crits.
3.75pounds. BOMBPROOF.
Frank had to talk me out of using one inch square tubing like we use on the DS bikes.
Seems like it'd be easier to draw tubes in that profile to start with rather than trying to get something attached the full length of the tube.So what would happen if you tried to braze/bond a flat sheet of alu or other material inside a tube to improve uni-axial stiffness?
Edit: The more I think about it the dumber it is but could make for some stealthiness.
Italians tried all sorts of stuff like that in the 90's. It doesn't do anything. Rad idea though.So what would happen if you tried to braze/bond a flat sheet of alu or other material inside a tube to improve uni-axial stiffness?

Glad to see that edu-macation is doing you some good (has practical applications).Ok, just did a little crude approximation, adding a rib of thickness equal to the wall thickness for some pretty typical bike tubing makes it about 18% stiffer along the axis of the rib, but adding that same amount of material to the tube walls directly makes it more like 26% stiffer, and not just in one axis, so it's kinda pointless. Presumably if you want to tune stiffness in different directions you're presumably better off ovalizing tubes, though I'm too lazy to calculate that one right now.
I will have no discussion of percentages in this thread.
We did drawings for an importer and they gave us a bunch of free ones.Looks quite interesting.
Question: why a PFBB30 vs. regular BB30? Is it for ease of manufacture? Availability of PF30 shells?
Just got orders for three more of them.I need to see parts on it to "tie the room together"
SRAM cranks on Shimano drivetrain...just sayin'Customer sent me a teaser.
Meow.
Yeah, he's got it backwards. Should be Shimano cranks on a SRAM drivetrain.SRAM cranks on Shimano drivetrain...just sayin'
But then he'd have to use BB30 reducers (at least on this frame).Nice work, Mickey. That bike is rad.
