Check a documented Shimano R7000 mechanical 2x11 upgrade: cassette, derailleur capacity, chain, freehub and crank interfaces. Unknown combinations stay unknown.
Version one covers only the listed Shimano 105 R7000 mechanical 2x11 components and factory chainring pairs. Source specifications were reviewed on October 25, 2026. It is not a universal Shimano, SRAM or Campagnolo checker. “Verified compatible” applies only to the interfaces shown, assuming the parts and measurements you selected are accurate. It does not approve brakes, hanger alignment, adapters, chain length, torque or a complete bicycle.
Example values are prefilled. Replace them with your own measurements or quotes. No account is needed.
Review the inputs, then calculate. Changing any input clears the previous result.
