At the heart of its flawless performance is the meticulously engineered narrow-wide tooth profile. This design features alternating thick and thin teeth that perfectly match the inner and outer links of your chain, creating a secure, interlocking fit. This system virtually eliminates the risk of dropped chains, giving you the confidence to charge through the roughest rock gardens, drops, and high-speed chatter without hesitation.

Built to withstand the harshest environments and most aggressive riding styles, the Renthal 1XR chainring is a benchmark in durability. It undergoes a specific hard-anodising process that significantly increases its surface hardness and wear resistance, ensuring it provides consistent, reliable performance ride after ride. Furthermore, the base of the chainring teeth features CNC-machined mud-clearing grooves. This intelligent design actively sheds mud and debris, maintaining optimal chain contact and preventing build-up in wet and sloppy conditions, which in turn extends the life of your entire drivetrain.

Precision CNC machining allows for an incredibly stiff yet lightweight structure, ensuring every watt of power you produce is transferred directly to the rear wheel. This efficiency, combined with its featherlight construction, makes it an ideal choice for riders from trail enthusiasts to elite enduro racers. Compatible with 9s, 10s, and 11s chains, this 104mm BCD chainring offers incredible versatility for riders looking to convert to a 1x system or simply upgrade their current single-ring setup.
