Rennen - 4-Bolt Chain Ring (Bicycle)
Rennen Sprockets are precision machined from aircraft quality 7075-T6 Aluminum ( 83% stronger than 6061) and polished to a beautiful luster or available in Stealth Black, offering the highest performance at the right price. Rennen Chainrings are 3/16” thick and are made to take the abuse of the BMX Track or a east coast muddy rocky SS ride. Only Rennen Sprockets offer a single speed specific tooth profile which have been designed to extend tooth life. At 2.8oz (79 grams, 38T) this makes Rennen Chainrings one of the lightest on the market.

Comments about Rennen - 4-Bolt Chain Ring (Bicycle):
Rennen chainrings, are ultra-light and 100% true. These are engineered for BMX racing. They're 7075- T6, which I prefer over the slightly softer 6061. In the drivetrain it makes all the difference.
