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 drivetrain? 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 pulleys. This corresponds to roughly 60% of the noise reduction. Practically speaking, the cage becomes very silent.

 

We use a patent pending solution, our special xring rubber suspended bands, that dampen the chain impact on the guide pulley teeth, therefore eliminating the engagement noise, which is the single biggest contributor to overall drivetrain noise. From now on, your ride is going to be more silent than it used to be and you will hear sounds that you haven’t noticed before. It's the new era of derailleur cages

 

WHY IS OUR OSPW HOLLOWCAGE® SO SPECIAL?

*It is Incredibly silent (over 12dB noise reduction vs stock).

*The shifting is as good as with the original cage.

*One of the lightest oversized cages on the market.

*First mono plate construction of its kind.

 

Our bearings are full ceramic. In technical nomenclature, it is a bearing with inner and outer race as well as balls, made of ceramic material. The seals and the cage however, are made of polymer. Other common types of bearings are steel bearings and hybrid bearings. The latter is often mistakenly called "ceramic" bearing but only the balls are ceramic, races are still made of steel. Hence there is a term "full ceramic" indicating that not only the balls are made of ceramic but both races too. Our bearing races are made out of 100% Zirconia Oxide ceramic and balls are made of Silicon Nitride ceramic. The cage and seals are of course made of low friction polymer.

 

FIND CORRECT CHAIN LENGTH FOR HOLLOWCAGE SRAM AXS

Wrap the chain around the biggest sprocket of the cassette and the biggest front chainring, omitting completely the derailleur cage. Holding the chain under tension, pull the ends together so they touch. This is the base length.Depending on the drivetrain you need to add the following to the base length:*Extra two links for 10-28T & 10-33T cassette in 2X scenario.

*Extra two links for 10-36T cassette in 2X scenario.

*Extra four links for 10-33 or 10-36T cassette in 1X scenario.

*Extra four links in 2X scenario only if you are upgrading from 10-33 to 10-36T cassette (ie. when your bike came with 10-33T but you upgrade to 10-36T).

 

Designed in England. Manufactured in EU. The World's best oversized derailleur pulley cage
