Anywhere from $3000 - $8000 for frame only(hell probably $10k+ depending on what kind of Sultan of Brunei shit you want), and you will be extremely limited should you want aluminum. Most custom frame builders are going to be steel, titanium, or carbon w/lugs. If you want your own design, linkage and everything, well...get a welder and some tools. In short, "more than you can afford pal!" - Ferrari driver from Fast and Furious. If you want a "custom"(need to be careful about what your calling custom) frame, get an Atherton Bike Co(formerly known as Robot Bike Co), they use a Dave Weagle designed linkage(DW6) and offer carbon frame with 3d printed titanium lugs and will offer any custom geo you like. Expensive, but IMO the "best"(see: coolest) custom frame you can get.
So is Connor racing a trail bike with a dual crown in the World Cup?
