The Rennen Threaded Chainring range is manufactured to the same standards as the regular 4 Bolt Chainring and is precision machined from aircraft quality 7075-T6 Aluminium (83% stronger than 6061) and polished to a beautiful or available in Stealth Black, offering the highest performance at the right price. Running from 32T right up to the big dawg 52T, these chainrings have all your professor gearing combos covered! The chainring bolt threads directly into the chainring for more security and quicker gearing changes, and less tolerances between hardware.
Rennen Chainrings are 4.76mm (3/16") thick and are made to take the horsepower of a BMX gate start and will stay true to handle the 180 RPM you're dishing out on the first tap out. Only Rennen Sprockets offer a single speed specific tooth profile which been designed to extend tooth life.
At 79 grams (38T) this makes Rennen Chainrings one of the lightest on the market - it might just give you that extra 0.01s out of the gate to save you getting sent over the first berm! 👊
