MUSA - Made in the USA frames by Cameron Falconer. The second run of MUSA frames by Cameron was produced a while back. All are for disc brakes. Available sizes are 56cm Green (only one) and International Orange, 59cm International Orange only.
Framesets are $1700 with fork. Frameset specs are: True Temper Verus tubing, Paragon Machine Works dropouts, segmented style fork with Paragon Machine works disc tab, rear disc tab is by Hunter Cycles. Geometry is the same as the current V4 cross frame. The chain stays have an s-bend to clear any crank arm and there is clearance to run 29" x 1.75" tires. Decals are applied on top of the finish.
Here's a blog post outlining the differences between the US made frame and the Taiwan made frame. This was for the rim brake MUSA frame, but the same applies for this disc frame.
