Ride Review: Steve Stefko’s Trek Boone

You guys remember that time Steve Stefko of Miiflo Cycling won the 2025 40-45 Cyclocross National Championships in Fayetteville, Arkansas? Yeah, that was pretty cool. A couple of weeks back, I had the opportunity to shoot Steve’s race-winning Trek Boone. Trek is among a dwindling number of major manufacturers that still produces a purpose-built cyclocross rig, and that’s exactly why Steve sought it out. Check out the review of his ride below.

Sad day- Something in the truck rubbed on the seat stay during transit to Nats. Steve sealed it with some heavy duty super glue/epoxy the evening he pulled into town.
