Looks like I'm going to need a new headset for my 2011 Whyte 901. Other than measuring is there any way I can find out the internal diameter of the head tube so I can order the right size headset?
After a lot of internet research it would appear that finding a replacement headset is an absolute bloody nightmare!
So many different sizes available! The problem I have is that so far I have been unable to remove the forks from my frame, so I'm unable to measure the tube ID.
I think I'm right in saying that I need to know both the ID and OD of the headtube before I order? I'm planning on having a shop fit it for me.
So far, through the process of elimination and educated guesswork I've been able to establish that I have a semi integrated FSA Orbit Z with a 15mm top cap - is it right that on FSA's own website they would describe a semi integrated headset as an internal or ZS style headset?
I'm so lost with all this!
