I love the reverse engineering of the layup. Were able to pick up enough information off of it to help build your layup scheme?

I only started with that and for now only analyzed a couple of small sections. I expected the down tube to be much beefier on the bottom side to protect from rock strikes. Other than that no real surprises for now. I have a fairly good understanding of the general layup from the research I did when i built the road bike, but it's a nice sanity check.
I would actually be most interested in cutting some chain stays and seat stays open, but don't have any of those...

I love pulling the layers of carbon apart, I used to do that with some nasty chemicals that would melt the resin away and leave the individual sheets. Wanted to get into carbon repair and building carbon frames so I have a stack of broken carbon frames in my basement - I was going to pull apart a few to study the layup then use that info to repair the others and see how they held up, but never got around to it.

For repairs you need to feather in the plys anyway so you will sand back the area around the crack and then you can already see the fiber orientation and can match it perfectly. There is a wealth of information available from the faa and other institutions that set guide lines for aircraft repairs. Well worth a read!

I took my frame fixture designs to the next level.

More precise, easier to make, cheaper to build. Perfect for modern high performance bikes.

This new design is really about the end of the development cycle for this.

29 or mullet wheel set up
Head tube 64.5
Seat tube 78
Reach 465
Chainstay 435
Wheelbase 1235
