We have stock of a number of SRAM Force post mount calipers for sale. These are all new an un-used, they are left over stock from groupsets that were fitted to cyclocross bikes where flat mount calipers had to be used instead. They may have the odd mark on from storage but have never been ridden.
There are two with front hydraulic hoses attached(76cm hose) and two without, the brake pads are original OE SRAM and again new. They will almost certainly require bleed when fitted back to a lever.
