Installation of Super CNC 12/14T Strummer Pulley on Shimano 105 Rear Derailleur

In the video below, you can see a customer installing the Strummer Super CNC pulley on a Shimano 105 rear derailleur (with a long cage variant). This rear derailleur (RD) has stock gears of 11 and 13T, so the user decided to upgrade the size to 12 & 14T.

The diameter of the pulley is larger, reducing the bends in the chain. The black ceramic bearings on this pulley have low friction, resulting in lower resistance during rotation. These two factors make the operation of the rear derailleur more efficient.

Hard alloy material, making this pulley durable for long-term use.

Narrow wide design also helps with chain retention (the chain is less likely to fall off).

Note: The making of this video is not sponsored by Strummer. The purchase of the product and the making of the video were done independently on one's own initiative.
