Description of ๐Ÿšฒ KCNC Road Cyclocross Gravel E-Bike Bicycle Rear Derailleur OSPW System Cage for Sram Red/Force/Rival Mechanical 10/11 Speed

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 for Sram red/force reach 30%-60%, or more in some cases, over a stock setup.Almost have the same efficiency ratio with Ceramicspeed. UPGRADE YOUR CASSETTE-The system is compatible up to a 32T cassettes on most bikes depending on derailluer hanger.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 for SRAM mechanical derailluers is compatible with both short cage & WiFli derailleur bodies.The system is for Sram Red/Force 10/11 speed mechanical rear derailleur use. SPECIFICATION-Top Pully :14T with sealed bearing / Bottom Pully :16T with sealed bearing / Matiral : AL7075 Fully CNC/ Color:Black,Red,Gold available / Weight : approx.60grams / For Road Sram Red/Force 10/11 speed mechanical rear derailleur.

Efficient and fast, the best in cycling

Not the easiest installation on a SRAM Rival derailleur (SRAM complicated). Once installed I found them efficient and quick. Worth the price.

Pros
  • UPDATE YOUR CASSETTE. The system is compatible with most bikes with cassettes up to 32 teeth, depending on the derailleur mount. Alloy 7075. Coated bearings extend life even further. The service life of oversized pulleys is 3-5 times longer than standard pulleys, which are widely used in the market.

Not suitable for SRAM Rival 10

The swivel funnel is a fraction of a millimeter shorter than needed to insert the locking pin. The photo shows traces of rubbing from the locking pin. I couldn't put the pen back in.

Pros
  • EFFICIENCY OSPW-Oversized Pulley System (OSPW) reduces disc friction by 45% for optimal performance. The overall energy savings of the OSPW system for Sram red/force is up to 30% to 60% and in some cases even more compared to the default setting. Almost the same efficiency with Ceramicspeed.
Cons
  • Band

Sturdy construction but chainline issues due to narrow width

Why use narrow wide wheels? Ordinary tension wheels do not bounce. I had to stop and adjust the chain several times because it was on the wrong teeth. So annoying.

Pros
  • COMPATIBILITY โ€“ SRAM's OSPW system for mechanical shifters is compatible with both short-cage and WiFli switch housings. The system is designed for use with a mechanical Sram Red/Force 10/11 speed rear derailleur.
Cons
  • Unsure

Looks tricky and does the job

Used to replace a broken cage on an old red 1st generation 10 speed derailleur. The replacement is easy enough, and I estimated all available positions for the tension spring so I could actually adjust the chain tension. This is also a good tip from CNC blingPro if you're having installation issues: find an old shift cable or brake cable and use it to hold the derailleur open, or leave the derailleur connected to the derailleur and shift into the largest Gear Use your bike's chain and wheelโ€ฆ

Pros
  • SPECIFICATIONS - Upper pulley: 14 tooth sealed bearing / Lower pulley: 16 tooth sealed bearing / Matiral: AL7075 Fully CNC / Color: Black, Red, Gold available / Weight: approx. 60 grams / for Road Sram Red/Force 10/11-speed mechanical rear derailleur.
Cons
  • Very Expensive

LOVE OS derailleurs, but Sram is struggling!

Good pulley system. I can no longer hear my chain. The only problem was the installation. Said it wouldn't work on the Sram Apex system... but it actually works. Sram made the pickup body about .0001" longer than the Rival or Reds body, meaning you won't be able to install the locking pin. To fix this I took a random orbital sander and sanded down the body as thick as a human hair (yes let Sham resize by thousands of inches so people can't attach add-ons like this...seriously shame? ). Needless

Pros
  • WHY USE A RAISED PULLEY WHEEL CAGE - Upgrade your drivetrain for maximum efficiency and superior performance. KCNC wheel bearings reduce friction, which reduces rolling resistance. Replacing your wheel bearings with an oversized pulley will maximize your energy return.
Cons
  • Slightly dented
