ULTRA-LIGHTWEIGHT AND WEAR-RESISTANT: Manufactured from CNC aluminium alloy to ensure maximum strength and durability with minimal weight (ultra-lightweight 10 g). CNC machined construction maximises quality and achieves a perfect appearance.
EASY TO INSTALL: Simply remove the screws that hold the pulley to the transmission and these parts or accessories can be easily installed with an Allen key. Make sure the screws are 11.5mm or longer to ensure compatibility.
REDUCED FRICTION: The inner bearing is designed specifically for cycling with minimal friction for smoother transmission and significantly improved performance; it uses smooth ball bearings and is a must-have accessory for your bike.
SUPER RESISTANT: The guide pulley is anodised to prevent rust and corrosion, thus ensuring long-lasting use. Adjust the derailleur wheel according to the size of the screw, don't tighten it too much as it will increase the friction with the rear derailleur and reduce the performance of the bike riding paddle wheel.
