I' looking to sell my SRAM Level Silver front and rear brake sets with 180mm, 160mm center lock rotors. Brakes have been used for 2 seasons and have recently been blead. They work great with no issues. Rotors have about 40 miles on them. I'm taking these off an XL frame. I have not measured the lines yet. I will include a new barb and olive as you will need to re- bleed the rear brake. I do have new SRAM hose lines I can include for an extra $20 each.
