The Rennen 4-bolt decimal chainrings allow you to dial in your gear ratio by fractions of a tooth. By making slight adjustments to the chainring circumference and tooth profile, decimal gearing provides slightly taller or shorter gear ratios, allowing for "in-between" gearing not possible with standard chainrings. CNC machined in the USA from aircraft grade 7075-T6 aluminum.

Teeth: 3/32"
Thickness: 3/16" (4.8mm)
