IIRC it was the either a red band or the factory blue, I know it was not the kevlar band - this pic was taken over 2 years ago - so it's escaping me right now..

I do know the fluid was changed every 50-75 runs and the drum was serviced every few seasons. This drum had at least 2 seasons ( 6-800 passes) when it was tore down. It needed to be cut after that.
