Ready (well, once it's powdercoated and has things like wheels and a fork) for the GDR, baby!
Here's the breakdown:
-51cm seat tube at 73 degrees. Oversized 31.8 with a stainless top sleeve for the first 2" or so where the post inserts (it takes a 27.2).
-145mm head tube at 70.5 degrees, ready for a tapered Fox 100mm fork.
-63cm effective toptube, 67.8cm front-center, and longish 45cm chainstays for a 112cm wheelbase. We wanted long and stable on this big fellow.
-12.2" BB height, clearance for 2.5" tires, Rohloff hub specific!
-S-bend Deda chainstays (beef!) and some NOS Burly cargo bike seatstays (ditto) that I bent to match.
Robert is a big dude, and he wants reliability over light weight, so the bike is made almost entirely of True Temper Supertherm (BMX) tubing. It's not light - almost 6# with the slider inserts bolted on. But when you're pulling a trailer on the Great Divide - an extra pound of frame weight is probably worthwhile.
