A narrow-wide chainring for 104mm BCD (4 bolt) setups.
 
The Funn Solo Narrow-Wide is designed for single chainring setups with 104mm BCD interface cranksets.
 
The narrow-wide tooth profile helps to lock your chain in place, doing away with the need to run a chain guide.
 
CNC’d from high-quality aluminum, the Solo is both tough and light.
