The Rennen 4 Bolt 104 Chainring range is precision machined from aircraft quality 7075-T6 Aluminium (83% stronger than 6061) and polished to a beautiful lustre or available in Stealth Black, offering the highest performance at the right price. Running from 33T right up to the big dawg 52T, these chainrings have all your professor gearing combos covered!

Rennen Chainrings are 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 stright tap out. Only Rennen Sprockets offer a single speed specific tooth profile which have been designed to extend tooth life. At 79 grams (38T) this makes Rennen Chainrings one of the lightest on the market.

 

Additional Specs: Rennen 4 Bolt Chainrings are 104mm BCD compatible and will work with 8 & 9 speed chains.
