THE NEW ERA OF SILENT PULLEYS. MEET THE SILENT XRING PULLEY ™
Does it bother you when you ride in a really quiet scenery but you can still hear your bike’s chain engaging the pulleys? This familiar clunking noise has been accompanying us on every ride for decades. It’s time for a change.
Common polymer pulleys are fairly loud, this has always been a norm. Aluminium pulleys are even worse as the material radiates the sound more than any polymer, making them louder. We are introducing a completely new generation of pulleys, which are able to reduce the sound level by 12-14dB when compared to stock Dura Ace pulleys. This corresponds to roughly 60% of the noise reduction. Practically speaking, the cage becomes very silent.
