1. get a bike shop to remove the crown race off that fork and remeasure
replace with this headset
[FSA No.42/48CF/ACB IS42/28.6 – IS52/40 Headset | bike-components](https://www.bike-components.de/en/FSA/No-42-48CF-ACB-IS42-28-6-IS52-40-Headset-p38028/)
What are you trying to do/figure out?
Do you want to replace the bearings?
Do you want to replace the headset?
I suppose the first question is what you’re wanting to do/achieve. If it’s a new headset, then measuring the head tube bores with the cups removed is the first step.
Now, I’ve seen it often the case that the manufacturer puts a super cheap ZS style headset in an IS style head tube. If that’s the case, knowing both the bore and angle of the bearing seat is useful.
If I had to guess, this Felt is probably that way, so you would probably need:
IS42/28.6 upper
IS52/40 lower
I replaced a Felt headset with this exact set up (cheap ZS in an IS) a few months back, and used a Cane Creek 40 with those dimensions above.
