For riders building wide-range gravel, cyclocross, commuter, or adventure setups, the Tanpan bridges the cable pull difference between road and MTB systems—unlocking greater gearing range and improved chain security without replacing your entire drivetrain.\u003c\/p\u003e\n\n\u003cp\u003eBy \u003cstrong\u003eamplifying road shifter cable pull\u003c\/strong\u003e, the Tanpan allows precise indexing with Shimano mountain rear derailleurs. This makes it possible to run larger cassettes and clutch-equipped Shadow+ derailleurs on drop-bar bikes. The result is expanded gearing for steep terrain, better chain control in rough conditions, and a simplified 1x drivetrain option for riders who want reliability without unnecessary complexity.\u003c\/p\u003e\n\n\u003cp\u003eWeighing just 18 grams, the Tanpan tucks neatly above the rear derailleur. An integrated indexed barrel adjuster allows quick cable fine-tuning, and the CNC-machined 6061 aluminum body is paired with a Delrin wheel and stainless steel hardware for durability and smooth operation. Each unit is made in the USA.\u003c\/p\u003e\n\n\u003ch3\u003eCompatibility Overview\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTanpan 11:\u003c\/strong\u003e Use an 11-speed Shimano road shifter with an 11-speed Shimano mountain rear derailleur.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTanpan 10:\u003c\/strong\u003e Use a 10-speed Shimano road shifter with a 10-speed Shimano mountain rear derailleur.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTiagra 4700:\u003c\/strong\u003e Compatible when using Tanpan 11 with an 11-speed Shimano mountain derailleur and 10-speed cassette.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGRX ST-RX400 10-speed:\u003c\/strong\u003e Use Tanpan 11 with an 11-speed Shimano mountain derailleur and 10-speed cassette.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDeore M5120:\u003c\/strong\u003e Compatible with Tanpan 11 only.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTanpan 10 Derailleur Compatibility:\u003c\/strong\u003e Shimano M980, M780, M670, M610.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Tanpan 11 mounts directly to adjuster-free cable stops on Shimano rear derailleurs.
