Flat Matters dropped some info on a Subrosa DTT Aggro Rag Limited Edition frame that’s dropping soon:
At Interbike 2012 Subrosa displayed their new DTT frame. They will be doing a flat specific model that Kip Williamson helped design. Ryan Sher said the TT is 19″ and the rear is around 13 slammed. The head tube is 75 and the seat tube is 71. The seat tube from center to center is about 8″. All brake hardware is removable and the BB is mid.
