Frame req? (Aero, dropped SS, high stack, short reach)

[hoot]

 Has press fit come a long way ? I had a couple Super Six Evos in 2012 and 2014 and the BB sucked bad. They were fine new but needed attention after only a couple years. (creaking) Also - T47 has lots of tool interface on a road BB and even on wider a 86mm bb are fine if careful. Just don't use shit tools/BBs. The only drawback is they don't look that nice.
 Now that I think about it I am sure the bb on my C50 and Master are original and they are 20 years old LOL.

Pressfit is very good as long as the BB shell is made within the correct tolerances (dimensions, roundness, alignment) and the Shimano pressfit BB is a nice design. I think most problems in the past were due to poor manufacturing. Recent frames have tended to be better (and I'm sure this one would be within tolerance!). When it's done well you end up with a system that's stiff due to the bearing spacing, and lighter than T47.

Who likes to have a handlebar like this with the frame Peter proposed ?
Drop ca. 100mm and with a rather high flare.
The concept is from Canyon (at least that is where I came across it) but with adjustable width, what I do not like due to the possible risk and instability.

But this handlebar is follwowing the same idea as the frame to have something with a different geometry instead of having a lot of offerings with identical geometry,

Love the geometry of those handlebars, but indeed I'd rather have them as a one piece / one size than a modular handlebar to avoid any safety issues. Have you seen already similar handlebars appear on the asian market?

I found this:

I asked Adapt if this is compatible with the canyon drops or if they can provide a quote to me but got no responce.
Another problem (exept from the joints) with the canyon bars is that it looks like if the stem-part is propritary:

and will only work with special or modified forks.
So far I only found not integrated handlebars (to be used with a normal stem) with ca. 100mm drop

 That's good to hear. My second SS frame I ended up getting praxis thread together bb, installing it and selling the frame.

Interested in seeing how this new frame turns out Peter

OK. So here is our goal to do this new frame, same standard as Faxxxx on headtube and bottom bracket testing.
One piece mold and latex molding
High stack, short reach, more aggressive geometry than Factor but less than Pina X
700*35C max tire clearance, UDH, T47 85.5mm bottom bracket, both top and down 52mm headtube
aero seat post but with two types seat clamps for either 7*7 or 7*9 saddle rails
dropped seat stay, aero design
Size 54cm weight would be around 895+/-30g after painted and with front and rear derailleur hanger mounted.
Here is my only question now: which position do you like the battery located ? Seat post or low side of bottom bracket ?

I would add to this list konger than usual headtube. Then we can have slamed stems. Battery for me wilk be better in the seat post.
