Im reading that if you want to upgrade 11spd Campagnolo to 12spd, no need to swap out wheels as the 12 spd cassette is campatible, however the drivetrains are not.

Any experience here?

Thank you!

The cassette body and wheels are the same for 9, 10 and 11s cassettes and for 12s cassettes starting on an 11 or 12 sprocket, i.e. those intended for use with current Chorus, Record or Super Record 12s EPS or mechanical groupsets.
These cassettes, provided the largest sprocket does not exceed 29T, are forward-compatible with the most recent Super Record WRL (wireless electronic) groupsets.

For cassettes starting on a 10T sprocket, you need to have a N3W type cassette body which is only compatible with disc brake, 12mm through-axle wheels.
These cassettes are only intended for use, at this time, with Super Record WRL (wireless electronic) groupsets.

For current Chorus, Record or Super Record 12s EPS or mechanical groupsets, where they are rim brake, the brake calipers are backwards compatible with other rim brake calipers.
The 12s hydraulic Ergopower levers are compatible with the H11 disc brake calipers.
Current Chorus, Record or Super Record 12s EPS or mechanical groupset Ultra-Torque bottom bracket cups are the compatible with 11s versions.

The UT-CN300 chain tool may be used for 11 or 12s (although it is marked "11s Only").
The BB tools, all of the disc brake tools, FD alignment tools, cassette lockring tool are all the same in 11s and 12s.

All other parts of the 12s groupset are "12s only" and mixing and matching is inadvisable & will void both the functional and the materials & workmanship warranty.

Thank you, just wanted to confirm that 11speed Campagnolo freehubs are 12speed cassette compatible, so no need to buy another wheelset purely for 12speed.

Correct!

Sorry, I meant to edit out the parts about calipers etc - it was a cut-and-paste to a similar query sent on Campagnolo's internal mail system!
