The Rennen Pentacle Chainring-5-Bolt is made from airplane-grade 7075-T6 aluminum alloy which is 83-percent stronger than the standard 6061-T6 chainring. This premium alloy is also super lightweight so even the 42T size weighs less than 2.5oz, 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. Designed for riders 14 years old and younger with a weight limit of 150lbs.
