Ratio, A UK Startup, Releases a 1×12 Mechanical Upgrade Kit for £49.50

The Ratio upgrade kit allows you to pair 11-speed mechanical shifters with 12-speed Eagle MTB derailleurs and cassettes. While it includes dissecting your shifter and derailleur, Ratio’s instructions are super clear and enable you to ride a wide-range 1×12 drivetrain on a gravel, road, or touring bike without the expense and hassle of electronics and batteries.

Check out the Upgrade Kit at Ratio. We just bought a kit, so stay tuned for a full-review in the near future.
