The Prowheel 104 BCD Steel Narrow-Wide Chainring is a durable and affordable replacement or conversion option for compatible mountain bikes and other bicycles using a four-bolt 104 BCD crankset.
Its alternating narrow and wide tooth profile engages more securely with the chain, helping improve chain retention across rough terrain. This makes it suitable for use in a single-chainring drivetrain, providing a simpler and cleaner setup without requiring a front derailleur.
Constructed from steel, this chainring prioritises strength, wear resistance and dependable service life. It is particularly well suited to recreational mountain bikes, commuters, e-bikes and high-use bicycles where durability and value are more important than achieving the lowest possible weight.
Available in various tooth-count options, riders can choose a smaller chainring for easier climbing or a larger chainring for increased speed on flatter terrain.

Compatibility
This chainring is intended for compatible four-bolt cranksets with a 104mm BCD mounting pattern. Before ordering, check your crank’s bolt pattern, BCD, required tooth count, chainline and chain compatibility.
A narrow-wide chainring helps retain the chain but may not eliminate the need for a clutch rear derailleur or chain guide in demanding riding conditions. It is not intended to provide front shifting as part of a double- or triple-chainring drivetrain.
