Roundagon

Brand: Avid

The Roundagon was Avid's stainless steel rotor for its Ball Bearing cable disc brakes, fitted as original equipment on the BB5 and BB7 in MTB and road versions. It used a six-bolt IS mount and was catalogued in 140, 160, 185 and 203 mm sizes, the 140 mm size being a road option for the rear only. SRAM's Avid spare parts catalogues list it from 2005 to 2009, alongside the slotted G2 and G3 CleanSweep rotors that gradually replaced it. In the 2012 Avid spare parts catalogue, the Roundagon no longer appears at all.
