1x Sram-Manolo 12 speed?

[Latestart]

What does PL think of this 1x setup for a drop bar City bike

SRAM Eagle GX - https://www.sram.com/en/sram/mountain/series/gx-eagle

Campy Chorus 12 ErgoPower - https://www.merlincycles.com/en-us/c...ed-165751.html

Jtek Shiftmate 2 to adjust pull ratio - http://www.jtekengineering.com/resou...compatibility/

This would be fit onto either an older Serrotta Ti frame or an older Independent Fab steel frame, both with 1" fork. This is a run-around bike that can handle steep hills without working up a sweat and simple shifting.

Thoughts?

Supposedly a 1x campy gorup is about to be released, might be worth holding off and seeing what it’s about

If it had drop bar shifters, it would be a great answer.

Does that work for 11 -> 11 and for 12-> 12?

I did not know that.

Be careful about this. There's a difference between "Exact Actuation" and "X Actuation", and they're not cross-compatible.

Whats the difference? I've done this with both 10 & 11 speed shifters/RD's (both road shift -> mtb RD and mtb shift -> road RD) with no issue. The 'x-horizon' RD's have better chain retention and require different setup, but that's been it.

I havent tried 12s yet, I dont think there's any mechanical 12s sram shifters yet.

For the OP, 11s rival setup with long cage RD will shift an 11-42 cassette, and I'd think that would be sufficient.

What are you trying to accomplish by mixing? Is there a reason you don't want to go with all sram or all campagnolo?

Looking for a decent 1x11 or 1x12 with drop bars and high range to use as a city bike in San Francisco for errands not exercise. Just 'spin' up hills.

I would like a high range in the rear. My largest gear on other bikes is either 34 by 28/30, so 11-40 rear? I haven't fully thought out the full range, but maybe 40-42 in the front?

This is going on a steel road frame, guessing the full set up will come in in the low 20lb range.

Just get SRAM 11s road shifters, SRAM wifli rear derailleur, and an 11-40 cassette. A Wolftooth Road Link will pull it all together.

You dont even need the wolf tooth, you can use a Rival/Force/CX1 long cage rear derailleur and get 10-42 or 11-42 easily, or in the case of my latest built a GX long cage. A 36-40t chainring should be fine for those hills.

One of the nice things about sram is that these setups work nice with no adapters, no road/goat/etc links, no rollamajig things that never shift flawlessly, etc, etc. If you get a shifter meant for a front derailleur you can pull the pawl out and operate a dropper post, too.
