Hi, I have a Trek Procaliber 9.8, 2016 model. Could you please confirm that this headset would be a suitable replacement on my bike? Many thanks

Hi Richard

Apologies for the late response, we're getting through enquiries as quickly as we can.

This isn't the correct replacement for your Procaliber.

Do you need a full headset or just the top and bottom bearings replacing?


Best
