The Inspyre Evo-C Disk Expert 19.5" BMX Race Bike takes the Evo Disk platform and upgrades the front end with a Pride Apex carbon fork — moving from chromoly to carbon at the fork without changing anything else. That's a meaningful upgrade: the carbon fork reduces unsprung weight at the most rotation-critical point on the bike (the front wheel), and the Pride Apex's StemLock system eliminates star nuts from the steerer for a cleaner, stronger setup.
Forward hubs (upgraded from the Evo's hubs), Tioga tires, and hydraulic disc braking throughout. The frame geometry is the same Evo Disk alloy platform. If you're choosing between the Evo Disk and the Evo-C, the question is whether the carbon fork upgrade is worth the price difference for your rider's current level of competition. At regional through national level, it generally is.

Frequently Asked Questions
What's the difference between the Evo-C and the Evo Disk?
The fork. The Evo-C ships with a Pride Apex Carbon fork — carbon fiber legs over an alloy steerer — where the Evo Disk uses a chromoly fork. That fork upgrade also brings Forward hubs vs. the Evo Disk's Inspyre Evo hubs. For riders competing at regional or national level, the carbon fork reduces unsprung rotational weight at the front wheel, which you feel most at the gate and through technical sections. If your rider is racing consistently and you're choosing between these two, the carbon fork is a meaningful real-world upgrade.
