Retired 4130 Fixed Gear / Single Speed · 2026
4130 - Purple Reign – (Fixed Gear / Single-Speed)
The 4130 Fixed Gear / Single Speed series took its name from the double-butted 4130 chromoly in its frame and fork, and Purple Reign was one of its colorways from 2023 until it was retired in January 2026. Redesigned geometry made room for 38x700c tires through a TIG-welded wishbone rear, with clearance recommended up to 45c. Tubeless-compatible wheels laced to drilled 40mm high-flange sealed-bearing hubs carried a flip-flop setup with a 16t freewheel and a fixed cog. Add 46x16 gearing, rack mounts, and long-reach calipers, and it was a single speed built for bad city roads, gravel paths, and light trails.
