The Rennen Pentacle Decimal chainring is CNC machined in the USA from aircraft grade 7075-T6 aluminum featuring built-in chainring bolt nuts for easy installation and Rennen's decimal gearing system that allows 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.
Teeth: 3/32"
Bolt Pattern: 5x110mm
Weight: 2.3 oz (44.7T)
