WHY USING OVERSIZED PULLEY WHEEL CAGE-Upgrade your drivetrain for ultimate efficiency and superior performance.KCNC Wheel Bearings reduce friction, which gives you a lower rolling resistance.Upgrading your wheel bearings to oversized pulley will maximize the return you get from your energy. THE EFFICIENCY OF OSPW-The Oversized Pully Wheel(OSPW) system reduces friction in the pulleys by 45 % and for your optimised performance.The overall power savings of the OSPW System reach 30%-60%, or more in some cases, over a stock setup. NARROW WIDE PULLEY&DURABLE CHAIN RETENTION-The OSPW for SRAM Eagle Mechanical features a narrow wide tooth profile to ensure durable chain retention.The system consists of Top 14t & Bottom 16t alloy pulley wheels fitted with low friction bearings and a lightweight cage made from 7075 Alloy.Coated bearings prolong the lifetime even further.The oversized pulley wheels have 3-5 times longer lifetime than the commonly used standard pulleys on the market. COMPATIBILITY-The OSPW system is compatible with Sram Eagle XX1/X01/GX/NX Mechanical 12 speed rear derailleur.The Oversized Pulley Wheels System has been proven to be the fastest pulley system in the world, providing energy savings starting from 2.4 watts.Almost have the same efficiency ratio with Ceramicspeed. SPECIFICATION-Top Pully :14T with sealed bearing / Bottom Pully :16T with sealed bearing / Matiral : AL7075 Fully CNC/ Color:Black,Red,Gold available / Weight : approx.71grams / For Sram Eagle XX1/X01/GX/NX Mechanical 12 speed rear derailleur use.

Great bolt on product!

I was a little hesitant to buy this cage but the price was right! Other oversized wheel cages are around $300. I use a SRAM Eagle GX derailleur with a 50t cassette and this oversized wheel system bolts right onto it! After a few small adjustments, this system is running smoothly! No rattling or clicking. One thing I noticed is that you tighten the hex bolts on the idlers. When I tested them they were a bit loose. Overall a great product!

Pros
  • OSPW EFFICIENCY. Oversized Pulley System (OSPW) reduces disc friction by 45% for optimal performance. The total energy savings of an OSPW system reaches 30-60% and in some cases more in an existing installation.
Cons
  • Expensive

As long as it works well. The durability is terrible, don't buy it.

So since this seems to be the only way to get a full frame for repairing an Eagle rear derailleur, it's still not a good option. I bought it to fix a broken one and keep it as a spare until I need it. I bought it last year but haven't had to change that on my bike until this week. Installation was pretty easy, they replaced the factory cage. The angle on this unit was definitely not right and I had to flex the cage a bit to align the road wheels with the cassette to shift properly. it made aโ€ฆ

Pros
  • SPECIFICATION - Upper pulley: 14 teeth with sealed bearing / Lower pulley: 16 teeth with sealed bearing / Matiral: AL7075 Fully CNC / Color: Black, Red, Gold / Weight: approx. 71g / For Sram Eagle XX1 / X01 / GX / NX With a mechanical 12-speed rear derailleur.
Cons
  • There are other interesting options.

WORKS FOR SRAM X01 AXS!

I rarely write reviews but wanted to thank this company for making this product. As of March 2020, Sram is NOT selling a lower cage for its AXS X01 rear drivetrain. They do NOT sell parts for the AXS X01 mech and do NOT have a crash replacement program. If you bend the lower cage of the AXS X01 like me, Sram won't help you. your recommendation? I'm sorry but you have to spend on another full course. I'm so glad that KCNC makes this bottom cage because it saved me from buying a whole newโ€ฆ

Pros
  • COMPATIBILITY. The OSPW system is compatible with the Sram Eagle XX1/X01/GX/NX mechanical 12-speed rear derailleur. The oversized pulley system has proven to be the fastest pulley system in the world, delivering energy savings from 2.4W. Nearly the same efficiency as Ceramicspeed.
Cons
  • Many things
