The customer wanted a classic hardtail mountain bike with 26" wheels and a few unconventional touches. The rear disc brake post mount is located on the chainstay, with its rear edge welded to the seatstay, effectively distributing the force to both stays. He also asked for it to be unfinished rather than with the standard sandblasted or brushed finishes. The frame is exactly as it was immediately after welding.
Another personal choice was to have the seatstays join to the sides of the top tube rather than the rear of the seat tube. The wider position of the upper ends allow good tire clearance while requiring less of a bend in the seat stays. There are ISCG tabs at the bottom bracket to mount a chain retention device if it becomes necessary to eliminate chain drop, since the 1x11 drivetrain lacks a front derailleur.
Cable routing is external for easy access, but the remote cable for the dropper seatpost runs down the downtube then pierces the seat tube near the bottom bracket.
