Specification Brand : Demeras BulletPoint1 : DEEP TOOTH GUIDE PULLEY: guide roller pulley is a deep tooth guide pulley with optimized inclined tooth shape, synchronized with the chain drive direction, making the entry and exit of the chain smoother. BulletPoint2 : 7‑12 SPEED SHIFTING SYSTEM: derailleur pulley reduces lateral misalignment, which shortens shift response time and improves shift performance. Suitable for 7‑12 speed shifting system. BulletPoint3 : IMPACT guide wheel is made of full aluminum alloy, impact resistant, anodized surface, effective of aluminum alloy body, anti and BulletPoint4 : CNC MACHINING: rear derailleur pulley is CNC machined and finished with a cutter, making the product look and feel better. It can be used for a long time and has a very good performance. BulletPoint5 : MORE EFFORTLESS RIDING: Rear derailleur pulley is not easily deformed by force, to cold, high temperature and corrosion, high transmission efficiency, and more energy saving riding.
