I don't like proprietary seatposts or racy geometry but there don't seem to be too many options like that in the road space. Only ones I can think of off hand are the Velobuild 066 and Elves Eglath
I also don't need 50mm+ tire clearance as I don't plan on riding gravel/off road. Just want a comfy road bike. I saw the Airwolf YFR068, the artist formerly known as the CFR505 etc. Basically looking for a frame with ~40mm clearance and more stack than effective top tube (somewhere around 550 x 535, no longer than 540 ETT)
What is out there?
