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