Website shows CX1 with a tapered headset and QR wheels - an odd combination that disqualifies all of the many repurposed 26" forks that have the suitable short A-C length required. To run those, you will need to change your lower cup on the headset or run a reducer (more money). Any tapered steerer fork will be longer and have thru axles. OTOH the Paragon suspension fork fits your bike as-is and is an upgrade for sure. I have a dual air Sid XX; its the real deal.

Note, the manufacturer took the time to spec a custom fork crown to aesthetically match your headtube size.

Fork swaps are expensive in tooling; chances are you are not going to do this yourself, ask the shop that will do the work what forks they can get.
