Rennen - 4-Bolt Threaded Chain Ring (Bicycle)

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 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.
