Rear Derailleurs Bicycle Pulley wheel ceramic bearing jockey wheel

Product description

*14T narrow-wide tooth guide wheel weight: 12g 

*Material: AL7075-T6 aluminum alloy CNC machining

*Installation size: 6MM/5MM/4MM 

*Color: Anode red, enamel, blue, gold, titanium

*Bearing: steel ball / hybrid ceramic bearing / ceramic Bearing 

*Scope of application: for the lower guide wheel of the transmission, please use the 12T narrow-wide tooth guide wheel with this pulley.

*This product is made of AL7075-T6 round bar CNC. It is finished with diamond knife, has diamond-like metal texture, and the appearance of the product is resistant to friction index. All good. Adopting the Japanese imported steel ball lining, the rotation has no resistance, which greatly reduces the frictional resistance and improves the riding efficiency. 

The design of the narrow-wide tooth rear guide wheel significantly improves the transmission speed of the transmission, and there is no abnormal sound during the shifting process, which better prevents the chain from falling off.

Why replace derailleur pulley

First, replace the original pulleys with these would improve the weak stretch of the original set, and make the up and down chain tension between guide wheel and cogs much more adequate. 

Second, the number of contact tooth or control tooth between chain and cogs of 17T is more during gear shifting, the more contact, the stronger the control power.

Third, after redesign the cage’s rotation curve, the distance between upper guide wheel and the cogs is improved.

Long story short, with all the features mentioned above, you would save 2.2 watts or more with each pedaling. That’s the equivalent of shaving 100g off a 10KG bike.
