Just checking whether anyone has had success or bad experience switching out the aerodrive bar/stem stuff on the newer trinity advanced TT (UCI legal version)?

Looks like a 1 1/8 headset. I wouldn't ask but something's come up in a frame/fork/stem only deal at good $ and the giant online info is pretty rubbish, maybe tail between their legs after the uci issues. Alternatively has anyone sourced these bars or similar parts from giant (AUS), possible Very $$?

Thanks for your help
