Chainrings Wolf Tooth 4 Bolt Stainless Steel Drop-Stop Chainring

If you are in need of a 4 Bolt Chainring, chances are Wolf Tooth have an option to suit. Made from a hardened and electropolished 416 stainless steel Wolf Tooth’s Drop-Stop Steel Chainrings are one of the best performing and longest lasting wide/narrow chainring options on the market. Steel chainrings will last 5-10x longer (or even more) than Wolf Tooth’s 7075 aluminium chainrings.

 

Drop-Stop technology is Wolf Tooth’s patented wide/narrow chainring design. The wide side of the tooth has maximum contact on the drive side which spreads the load and improves chainring life. The narrow side allows clearance for mud and debris which reduces friction. Alternating wide/narrow tooth pattern prevents chain derailment
