Solo Narrow-Wide

aluminium. MTB.

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 chainguide.

CNC’d from high-quality aluminium, the Solo is both tough and light.
