TA One X110 GRX ChainringFeaturing a gravel-specific design and rugged durability, this high-quality chainring is an ideal choice of upgrade for riders with Shimano GRX 10/11/12 speed chainsets. This gravel bike chainring is equipped with a hard-wearing 7075 T6 aluminium build, which makes it suitable for handling all the challenges associated with gravel riding. Whether you're taking the long road home or exploring countryside back roads, this model's narrow/wide tooth shape enables your chain to stay in place without the use of a chain guide. Coming complete with a four-bolt pattern, it is ideal for replacing the old or worn-out existing chainring on your Shimano GRX 10/11/12 speed chainset.Please note: These chainrings are designed to be compatible with the modern chainsets that have a cut-out on one arm, they are also backwards compatible with the earlier chainsets that do not have the cut-out.Features: Material: 7075 T6 Aluminium Use: Gravel Size: 110mm PCD Compatibility: Shimano GRX 10/11/12 speed chainsets Speed: 10/11/12 speed Bolt Pattern: 4-boltManufacturer's Part Numbers: CRQ338 Black 38T CRQ340 Black 40T CRQ342 Black 42T CRQ344 Black 44TBuy TA Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
