- HOLLOWcage has a carbon-polymer mono-plate construction with bespoke, oversized, full ceramic bearings and advanced silencing pulleys- Special X Ring rubber suspended bands dampen the chain impact on the guide pulley teeth, therefore eliminating the engagement noise, which is the single biggest contributor to overall drivetrain noise (over 12dB noise reduction vs stock)
- The shifting is as good as with the original Dura Ace cage. Abnormally large, bespoke, full ceramic bearings make the pulleys incredibly stiff and very tall teeth of the upper pulley gives the best possible shifting precision
- The mono plate cage can dynamically adapt to the chain angle as it allows the cage (and therefore lower pulley) to align better with the angle of the chain when using the higher gears of the cassette. This means less friction (and less watts lost) as the pulley doesn’t have to fight against the chain itself
- Adjustable spring tension lets you adjust for cassette size and chain length to find the lowest possible tension (and lowest watts lost) for your needs
- Compatible with Compatible with Shimano Dura Ace 9100 / 9150 / 9170 , Ultegra 8000 SS/ 8050 SS. NOT COMPATIBLE WITH GS LONG CAGE DERAILLEURS. Fits up to 32T cassette
- Box includes: Complete cage, lockring tool, 2x spare xring rubbers.

Arrived damaged
Color: Black, Size: 4 Panel Basic
Unfortunately, very cheaply made. It arrived with one of the connecting tubes cracked horizontally. Possibly due to bad welding. It is quite a headache to assemble. It was delivered on time but returned for a refund.

Not a great experience but a fine product
Color: Black, Size: 4 Panel Basic
not enough screws were included to make the wall. I was able to locate more screws to finish building-so I didn’t have to return the product- but it was a pain and I got lucky finding the pieces I needed
but it could’ve been a fail and a returned product

Useful, simple room divider
Color: White, Size: 4 Panel Basic
All the pieces were accounted for, and some even had extra pieces, maybe just in case they need changing. It was a bit like putting together a piece of IKEA furniture, though I went slower than usual so as not to make any mistakes. It wasn’t too hard to put together myself, and helps give my studio apt a feeling of space and privacy for my bed. I only wish it had a lovely Japanese design on it, but it does amazingly seem to match the wall color.

Multi purpose divider
Color: White, Size: 4 Panel Basic
I am excited this divider is being used to block off a portion of the dining room where I stored extra supplies. It looks nice!
