Product Description

You're ready to make the jump to bigger and better things, but you just got a sweet new wheelset that you're not ready to part with. No worries — we understand, which is why we offer our ROTOR 1x12 to 1x13 ROAD + GRAVEL Compatible Kit. This sleek kit sets you up with a 12-speed ready one-by setup, including a 1x12 cassette, along with a 12 -and- 13 speed compatible groupset, so you can start off with your current hubs, and upgrade to 13 when you're ready. Our 12 and 13-speed compatible grouppo offers seamless shifting, and a sequential gear range that accommodates all kinds of cyclists in all kinds of situations. 

We achieve this with a 1x12 single chainring hydraulic system that keeps weight at a minimum, while prioritizing aerodynamics for a reliable solution that lets you focus on your pedaling rhythm as you hammer up treacherous mountain roads, instead of worrying about exactly where to make that pesky front-derailleur shift.

1x12 to 1x13 is designed with all disciplines in mind, with cassettes crafted to offer ranges that appease road, gravel, and cyclocross riders alike, so you can pick the combination that best suits your needs, whether your goal is to hit the highest speeds on the peloton, or have the biggest bailout cog for steep fire roads when you're chasing wily DH descents. We achieve this flexibility thanks to the near perfect sequencing of gears, and a robust derailleur that can handle any terrain. 

To keep things compatible and retrofit-able, we craft our 1x12-1x13 groupset with a 1x13 Rear Derailleur that features a clutch mechanism that enables you to switch the setup from 1x13 to 1x12 speed on a whim, allowing you make the most of your current freehub, while reaching for bigger gear ranges, without the pesky front derailleur.

Our 1x12 - 1x13 Compatible Kit is built for those of us with a budget to stick to, but bigger dreams filled with extra cogs. This kit enables you to keep you current transmission with any standard HG Freehub, but reach new highs with our 12-speed cassette. This entry-point kit lets you move to a lighter, sleeker setup with than your old 2x groupset, and future-proofs your setup so you can step up to 13-speed in your own time.

Lightweight & Robust

With fewer components on board, ROTOR 1x12 to 1x13 slims down to featherweight scaling, while benefitting from maximum rigidity and optimal structural efficiency from modern disc brake systems. It features cutting edge Spanish CNC manufacturing to strike the perfect balance between lightness, precision, and durability. 

Built up with that extra cog our 1x13 scales in at just 1,785g, including shifters, derailleur, brakes, and hydraulic hosing (flat mount calipers, uncut hoses: 1,800mm x 3mm / 1,800mm x 5mm, 160mm rotors, all hardware included, 10-36t 13-speed cassette, and 126-link chain, uncut), enabling you to build your superbike to the UCI standard 6.8kg with ease.

Switching things up from the mechanical groupset you know well, the 1x12 to 1x13 kit is designed with indexing located in the rear derailleur, as opposed to shifters, which helps deliver its crisp, precise shifting inside of the robust casing. By locating the component weight in the back we're able to better distribute weight, and add more natural balance and stability to your ride. And in case you get a little wild on the road or trail, the 1x13 derailleur is protected by our reinforced Armored Box that protects against all external elements, shocks, and impacts.
