Title: Mixing Road/Gravel/MTB components - will this work ?
Post by: Ultramic on May 17, 2025, 10:47:01 PM

I have a pair of R7120 12 speed road shifters that I would like to repurpose for my gravel bike. I know I can mix it with the rx610 and rx820 2x setup but I was wondering if this 1x setup will work:

- R7120 road shifters ( left shifter will become redundant)
- RX822 gs/sgs rear derailleur
- M6100/7100/8100 crankset or rx610/820 1x crankset
- M6100/7100/8100/9100 cassette ( I will need a microspline freehub).
- M6100/7100/8100/9100 chain.

My logic is that the shifters are compatible with the rear derailleur which in turn is compatible with the MTB cassette. Then the crankset and chain just need to be in the same series.

Alternatively, I can lose 1 gear and wait for the CUES 1x11 dropbar to become available.

I don't see why it wouldn't. The Q Factor doesn't matter in 1x, the shifters are using the same 1.4 pull ratio and your whole drivetrain is from the same series. You might need to shim your cassette but that's about it
