Fixed-Gear (FG)¶

• Phil Wood Fixed Hub: Drop-in track hub—requires flipping chainline to ~53 mm.
• Freewheel vs. Track Cog:
• Track cog → fixed (flip-flop hub if available)
• Freewheel (easier to coast) but risk of cross-threading on fat-bike shell.

Safety Note¶

• No coaster brakes on fat bikes—front brake mandatory. Always run a front disc brake if you’re doing FG.
