{"product_id":"crankstel-rx820-12-sp-42t","title":"Shimano Crankset RX820 12-Speed 42T","description":"\u003cp\u003eThe Shimano GRX FC-RX820 12-speed crankset with 42T is the advanced choice for gravel riders who prefer the simplicity and efficiency of a 1x drivetrain. This top-tier aluminum crankset is specifically designed to work seamlessly with the new 12-speed GRX cassettes, offering a perfect balance between lightness and robustness for the most challenging off-road conditions. The 42T chainring size is optimized to provide a gear range suitable for both fast flat sections and steep climbs when combined with a wide-range cassette.\u003c\/p\u003e\n\n\u003cp\u003eThis crankset utilizes Shimano's leading Hollowtech II construction. The hollow crank arms and integrated 24 mm axle ensure exceptional stiffness at a low weight (approx. 655 grams), which is crucial for direct and efficient power transfer on rough terrain. The use of 800-series aluminum guarantees the durability needed to withstand the impact of stone chips and mud on gravel roads. Furthermore, the 1x system results in a lower chance of chain issues and less maintenance.\u003c\/p\u003e\n\n\u003cp\u003eThe GRX RX820 maintains the gravel-specific elevated chainline of 50 mm and a Q-factor of 151 mm. These unique dimensions provide crucial extra clearance between the chainring and the chainstay. This allows for wider tires and increases compatibility with modern gravel and mountain bike frames, which is essential for grip and stability. The 42T chainring features Shimano's Dynamic Chain Engagement (DCE) technology, where the tooth profiles are designed to hold the chain and minimize the chance of chain drop on the bumpiest trails.\u003c\/p\u003e\n\n\u003cp\u003e{snippet alias=\"oem\"}\u003c\/p\u003e","brand":"Shimano","offers":[{"title":"BLACK \/ 170mm","offer_id":53485632520535,"sku":"IFCRX8201CXB2","price":244.99,"currency_code":"EUR","in_stock":false},{"title":"BLACK \/ 175mm","offer_id":53485632553303,"sku":"IFCRX8201EXB2","price":244.99,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1005\/2570\/3511\/files\/crankstel-rx820-12-sp-42t-237964.png?v=1778085341","url":"https:\/\/woest-sport.com\/en\/products\/shimano-crankset-rx820-12-speed-42t","provider":"Woest Sport","version":"1.0","type":"link"}
