There are oversized pulley cages, and then there’s the absoluteBLACK HOLLOWcage OSPW system. With the most unique looks on the market, and a wild design that puts the bearings as far out as possible, it’s one of the most interesting upgrades you can make to your road bike.

absoluteBLACK claims it’s lighter, quieter, more aerodynamic, and reduces drag better than other oversized pulley systems on the market, and now you can win one of these $699 cages for your Shimano Dura-Ace R9000 or Ultegra R8000 rear derailleur!

absoluteBLACK is also giving away two bottles of their $145 GRAPHENlube wax chain lube! All you have to do is answer a few short questions and a valid email below to be entered to win!

    Love these oversize pulleys. But I ride Campy so mostly have to listen from afar. And I have ridden shimaNO and Scam. Just like Campy better

    These are hilarious. I hope I win the comp so I can put this on my 7-yo son’s full suspension bike, the chainguide on it is a bit draggy so saving a couple of watts on the 10 speed Deore rear mech would be a massive bonus. I’ve got a dremel and access to all the specialty fasteners in the hardware store so I’m sure I can make it work 🙂
