Does anyone have this frame? http://www.ebay.com/itm/700C-Carbon-Gravel-Bike-Frame-12-142-Disc-Brake-Flat-Mount-for-700C-40C-/152424772780?hash=item237d3974ac:g
Geometry looks almost identical to the Open Up. This frame can take a wider tire, up to 2.1 inch versus the Carbonda which takes 1.85 (47mm). I would have considered this frame, but their smallest size would still be big for me.
I'd be interested in more information too. And, yes, almost identical geometry to the Open U.P. I found another on eBay asking $1,050. The above seller has 0 feedback as of now. I wonder what offer would be accepted. The only negative re geometry for me on the 50cm is the headtube angle of 69.5.
I've been looking for another frame for a bunch of parts I have after converting my Ridley to Di2 and upgrading some of the other components to carbon. I also have some extra wheelsets too so have almost all the parts needed for a new build except a frameset. So I've been looking for an inexpensive thru axle frame. I was thinking steel - like the Twin 6 - but most are QR. So either of these two bikes look like an option.
