Giant Defy Alloy - Headset Bearings

hairy_boy

Hi,

I bought a second hand 2015 Defy Alloy 2: https://www.giant-bicycles.com/gb/defy-2-2015

Ran it through last winter and all was good. Rode it last night and had a creaking from the headset. I can try re-greasing the stem, spacers and bearings but thought about changing the headset bearing s ahead of this coming winter.

Can someone point me to which headset bearings to purchase ? Specsheet says its an overdrive steerer
