RENNEN 4 Bolt Threaded Chainrings

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.

*****New Threaded*****

Rennen was the first to introduce Integrated Chainring bolt nuts on our 110mm BCD chairings, Now you can get the same great innovation for our 104BCD 4 bolts. With our newest Chainring inovation you will never have to use a chainring wrench again. We have machined into the gears the internal Threads increasing accuracy and eliminating the frustration.

Chainrings are available in all sizes from 32T- 52T, 104mm BCD compatible and will work with 8 & 9 speed chains.
