An innovative adjustable stabiliser uses spring force and friction to maintain tension through the chain, which prevents it from dropping and reducing noise from the drivetrain. The upshot is smoother, more reliable shifting no matter the surface, so whether you are riding bumpy gravel or smooth tarmac the derailleur functions with predictable crispness. You can even incorporate this into your regular electronic road-riding setup because the derailleur is compatible with current road Dual Control Levers.\u003c\/p\u003e\n","brand":"Shimano","offers":[{"title":"34T \/ Black","offer_id":54308168434010,"sku":"1051718","price":269.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0956\/0827\/5290\/files\/Shimano-GRX-815-Di2-11-Speed-Rear-Derailleur.jpg?v=1781538985","url":"https:\/\/checkout.sigmasports.com\/products\/grx-815-di2-11-speed-rear-derailleur-17taf","provider":"Sigma Sports","version":"1.0","type":"link"}
