Enhance the performance of your bike with a Narrow-Wide chainring made by Garbaruk. The oval, aluminium Direct Mount chainring is compatible with the Shimano XT FC-8100/8120 as well as the Shimano SLX FC-M7100/7120 1/2-speed crank.

The special feature of narrow-wide chainrings is the teeth's changing width; narrow and wide teeth alternate to prevent chain dropping. In addition, Garbaruk chainrings feature an increased tooth height which improves the chain retention while the bike is shivering and jolting. Compared to regular chainrings, the special tooth shape guarantees a tighter contact with chain and softer pedaling.

To reach an optimal drivetrain chainline value, chainrings by Garbaruk's feature Variable ChainLine Technology (VCLT) which means that each number of teeth has got its own individual chainline. Apart from this, chamfered edges and wide mud gaps keep the chainring from getting too dirty. The Garbaruk chainrings are made of highly durable 7075 aluminium which not only guarantees a long lifetime, but also makes it possible to reduce the overall bicycle weight in a range between 150 and 400 grams (without front derailleur and chain guide).
