I went ahead and worked ahead. Grant had us up to seat tube angle. I did chainstay next, and then seat tube length, which allowed me to connect the dots for my seatstays. Then I marked my saddle height and drew a level line from the saddle to the front end. I knew I wanted to be able to get the bars and saddle level with a Nitto Pearl stem. I ended up with a slightly sloping top tube (more slope than a Hilsen, less than a Bomba/Hillborne) and still had my standover at a comfortable level. Then I dropped the headtube angle to the ground and pulled back the trail, which positioned my front hub and established fork rake. I went ahead with the compass and spun the wheels in, and from that marked where I want the brake bridges. I kind of guessed where the downtube meets the headtube. But the thing is drawn. It's basically a slightly modified 58cm 650B Hilsen/ Saluki.
