little off topic: i wont buy any new frame without a yoke. saving what, 100g? ok. But losing about 50% BB area stiffness is lame.
the only really good thing Onza made the past few 2-3 years is the tensioning system on the current Limey... everething else was there already (e.g. the whole Zona line... i mean come on?!).
Same thing with this cls proto. It's not like a python... it is a python with a different design.
ok, enough hating. Here's some serious input:
loving the long seat-stay design - gives a great overall stiffness as seen on the Python, saint blaise or the Canibal 1.
I'm not a fan of those bulky dropouts. This screw tensioning system works fine on the Kortz, Caelifera with regular sized dropouts.
If you want to make a long mod I would suggest 1055mm with 72° or even steeper ... otherwise its going to ride like a small stock.
edit:
i heard you dont really need a gusset when using hydro forming, is that so? Otherwise: why no gusset on the downtube dammit!!
