{"product_id":"shimano-fc-rx600-grx-11-speed-1x-crankset","title":"Shimano FC-RX600 GRX 11-Speed 1x Crankset","description":"\u003cp\u003eSimplicity is one of the strongest arguments for a 1x gravel setup — one shifter, no front derailleur to trim, and no chain drops when you're bouncing down a washboard descent trying to keep your line. Shimano built the GRX FC-RX600-1 crankset around that logic, using a purpose-designed 40T chainring rather than adapting a mountain bike crank to a drop-bar bike. It slots into the 11-speed GRX ecosystem at the second tier, sitting below the RX810 in the hierarchy but sharing the same asymmetric 110mm BCD so chainrings interchange between the two.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1x11-speed crankset designed for GRX gravel drivetrain\u003c\/li\u003e\n\u003cli\u003e40T chainring with alternating tooth profile for chain retention\u003c\/li\u003e\n\u003cli\u003eHollowtech II 2-piece construction with 24mm steel spindle\u003c\/li\u003e\n\u003cli\u003eAsymmetric 110mm BCD compatible with GRX 800-series chainrings\u003c\/li\u003e\n\u003cli\u003eAluminum crank arms available in 170, 172.5, and 175mm lengths\u003c\/li\u003e\n\u003cli\u003e49.7mm chainline optimized for gravel tire clearance\u003c\/li\u003e\n\u003cli\u003e151mm Q-factor\u003c\/li\u003e\n\u003cli\u003eCompatible with 135\/142mm road disc hub spacing\u003c\/li\u003e\n\u003cli\u003eRequires Hollowtech II bottom bracket (BB-RS500 threaded or BB-RS500-PB press-fit, sold separately)\u003c\/li\u003e\n\u003cli\u003eWorks with Shimano HG-EV and HG-X11 11-speed chains\u003c\/li\u003e\n\u003cli\u003e753 grams (172.5mm)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BRITKEN","offers":[{"title":"Default Title","offer_id":58762133963136,"sku":null,"price":0.0,"currency_code":"KES","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2063\/9235\/files\/rn-image_picker_lib_temp_06e98ee3-b89d-4c63-83f8-5e6676a92c0c.jpg?v=1787556825","url":"https:\/\/britken.com\/products\/shimano-fc-rx600-grx-11-speed-1x-crankset","provider":"BRITKEN","version":"1.0","type":"link"}
