Shimano SM-CRM80 lánckerék für XT FC-M8000-1 32 Zähne 96mm

The tooth profiles of the 1x11-speed chainrings on the new DEORE XT cranksets, like the XTR, have a significantly wider shape of the steel teeth and a special hook design. While the former, especially when pedaling ensures a safe guidance of the chain, the latter guarantees an efficient protection against the jumping off of the chain even in rough terrain. Overall, the new tooth design keeps the chain 150% stronger on the chainring, which significantly improves both safety and durability.

Shimano's front shifting system is based on the HyperDrive concept. Derailleur, HG chain and SG-X chainrings work in a coordinated combination and make shifting ahead more reliable, faster and more accurate. Without HyperDrive, problems quickly arise, especially under load, when switching from the middle to the large chainring. Shimano's HyperDrive system eliminates these problems. The guide teeth, the SG-X chainrings, the super-stiff Wide-Link derailleurs and the special profile of the HyperGlide link plates have been designed to work perfectly together as a system, ensuring clean, trouble-free shifting. The chainrings have exceptionally high torsional strength. The profile of the teeth is specifically shaped so that when shifting in both directions the chain can slide and be picked up cleanly.

Hollow outer chainring. The highly stable hollow construction reduces weight without losing strength. Better power transmission and faster, more precise chainring changes are the result.
