Kit Finder

//Find your ideal ratio setup//

Use the selector below to help select an upgrade kit to increase the range or number of speeds of your existing drivetrain. Our kits help you reuse old 10/11spd SRAM shifters/derailleur and use them with 12spd or 13spd.

For example, you want a wide range 10-52t 12spd cassette on your gravel bike? No problem, just enter your current shifters, derailleur and cassette you intend to use, then the selector will tell you what Ratio products you need to buy!

Got a damaged cage? Just follow the selector through and you’ll be shown a suitable replacement.
