About This Product: Rennen Chainring-4-Bolt

The Rennen Chainring-4-Bolt at J&R Bicycles is made from airplane-grade 7075-T6 aluminum alloy which is 83-percent stronger than the standard 6061-T6. This premium alloy is also super lightweight so even the 38T size weighs less than 3oz, one of the lightest out there. Rennen designed these cogs with a single speed-specific tooth shape for added durability and the spline interface is 3/16" thick to protect your hubs. These 110mm BCD chainrings also feature integrated bolt nuts which eliminates the need for a chainring wrench and allows for more accuracy.
