Ratio’s New 1×12 Road Upgrade Kit Converts 10 or 11 Speed to 12 Speed

We recently featured Ratio’s 11-speed to 12-speed conversion kit on John’s Crust Dreamer using Apex shifters and an Eagle GX rear derailleur. But what if you have 10-speed shifters and you want to convert them to 12? Well, that’s where the new Ratio Upgrade kit comes into play! This upgrade kit allows you to pair 10 or 11 speed mechanical SRAM shifters and a 1x-specific Exact Actuation™ derailleur with a 12 speed eTap™ AXS™ cassette and chain. This delivers a greater gear range and closer gear ratios without the expense or weight of electronic shifting…

See more at Ratio and YES, these kits really do work great!

Workbench Review: Ratio’s 11-Speed Road to 12-Speed Eagle Drop Bar Conversion Kit

I’ve got this bike. It’s a touring bike. So when it’s loaded down with gear, it can get quite heavy. To remedy this, I built it up with an Eagle GX rear derailleur and cassette, giving me a whopping 10-50t range (the new GX goes to 52t even). To shift this range, I used a barcon shifter from Microshift because as you are well aware, SRAM doesn’t make a cable-actuated road shifter that’s compatible with their MTB mech lineup.

Now, there’s nothing wrong with the Microshift barcon. I was and have been more than pleased with this option but then Ratio, a small startup out of the UK announced a 11-speed road to 12-speed mountain upgrade kit.

I think this is one time when we can ignore that old Eddy Merckx adage “Don’t buy upgrades, ride up grades…” Sorry Eddy, Johnnie’s bike needs this.

We posted about Ratio’s kit back in October. I ordered a kit the day the post went up but didn’t get motivated to do the install until I felt like I had a reason to. A few friends here in Santa Fe are taking on an all-road tour in April, and I wanted to get this bike dialed in before that trip, so last week, I swung by Sincere Cycles with the Dreamer and Ratio’s kit with hopes of rolling around on an 11-speed road shifter working with a 12-speed mountain…

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.
