RENNEN 4-Bolt Non-Threaded Chainring
Unable to load collection availability
Description
The Rennen 4-bolt non-threaded chainring is the standard version of the flagship model from American manufacturer Rennen Design Group, CNC machined in the USA from aerospace-grade 7075-T6 aluminium — an alloy rated 83% stronger than the 6061 aluminium used on entry-level chainrings.
With a thickness of 3/16" (approx. 4.8 mm) and a weight of 79 g in 38T, it is among the lightest chainrings on the market. Its dedicated single speed tooth profile has been designed to extend tooth life, a detail often overlooked on machined chainrings.
This is the version offering the widest range of tooth counts, from 38 to 52 teeth: perfect for equipping a youth setup as well as a Cruiser with a high gear ratio. Non-threaded bolt holes: make sure to provide a chainring bolt and nut set suited to your crank arm thickness.
