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.
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 for 2011! Rennen was the first to introduce Integrated Chainring bolt nuts on our 110mm BCD chainrings,
Now you can get the same great innovation for our 104BCD 4 bolts.
With our newest Chainring innovation 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.
