Made from 4130 chromoly tubing with a heat-treated integrated headtube that’s extra tall to eliminate the need for headset spacers, gyro tab holes, a double-butted top and downtube with Subrosa logo gussets, heat-treated Mid BB shell, seatstay bosses for removable U-brake mounts (sold separately), all new custom designed Subrosa wishbone junction and 6mm thick heat-treated dropouts.
The wishbone/ yolk is the biggest addition to the version. It’s a custom designed cast piece that allows clearance for the widest tires on the market while adding a ton of side-to-side strength to the rear end.
