KCNC Long Tooth UL Ultra Pulley Wheel is the ultralight version of KCNC’s long-tooth derailleur pulley, designed for modern rear derailleurs that benefit from increased chain guidance and retention. The longer tooth profile is commonly used on newer 11-speed-and-up drivetrain designs, where chain control through the derailleur cage is more important than on older short-tooth pulley systems.
Machined from 7075 aluminum, the UL version uses a more heavily relieved spoke profile and redesigned bearing dust cover to reduce weight compared to KCNC’s standard long-tooth pulley. It uses a steel cartridge bearing and is sold individually in 11T, 12T, and 14T sizes.
Compatibility Note: Derailleur pulley fit depends on tooth count, cage clearance, pulley position, bolt size, and derailleur design. Match your original pulley size and confirm clearance before ordering. Sold individually.

UL Version Notes
The UL version uses a more aggressively machined structure than the standard KCNC long-tooth pulley to reduce weight. It is the better choice when the goal is the lightest steel-bearing version of KCNC’s long-tooth pulley design.
Long-Tooth Pulley Notes
Long-tooth pulley wheels are used on many modern derailleur designs to improve chain guidance through the cage. They can also be used on some older compatible derailleurs when tooth count, cage clearance, and pulley hardware match correctly.
