Which Groupset?

next inane groupset chat question - will a Rival22 (11speed) shifter work with an Apex1 (11speed) long cage rear derailleur?

Is there a new DA 9150 coming soon?

I'm building up a 1985 Daccordi as a neo retro road bike.

Definitely want to go Campag.

Potenza seems to fit the bill, particularly the ability to have a 32t cassette.

But, I would rather rnot have the ugly modern crank set. Athena looks so much better. But then I have to put up with the pain in the backside crank removal issues.

So, how do I get mainly potenza, in silver, with a 32t cassette but with a non ugly, non retarded, compact chainset?

Why do you need a compact? A 39x32 will get you up anything.

Built like a climber, climb like a sprinter.

You're probably right, but in all of my time riding road bikes I have never wished for a higher gear but always want a lower one, on every ride.

My current road bike which will be replaced by this bike, has a compact. I can't remember what size sprocket it has on the cassette, mind...

You can get polished alloy compacts, from the likes of TA and Stronglight, so probably worth checking them out.

I assume you want polished alloy for that retro look?

This.

Spa Cycles have some nice looking one that you can choose with TA ring.

Even the one with the cheap ring costing £25 work well.

There were polished Athena cranks with UT axles, 10s. They work fine with 11s in my experience.

I've got a cabled S-Works Tarmac with 7800 DA on it. Can I run Di2 neatly on it? Will it require drilling? I have a sudden dislike of cables for some reason...

Externally or internally routed? I'm guessing the former...

If you could overcome you passion for drilling. Etap.

I think I’ve got a silver Athena 11sp compact chainset in the loft if you’re interested?

That's good to know. I'll see how things develop and be in touch. Is it the one with the impossible to remove cranks? Powertorque?

Get this.

Which is what?
And costs how much?

Cycle retro. Got it.

yes. 11spd road and cx stuff (and all 10spd stuff iirc) has the same cable pull, only 11spd mountain is different.

Sram says no
Apex 1 RD:
COMPATIBILITY 10-speed and 11-speed SRAM 1x™ road systems

Rival 22 Mechanical Shifters:
COMPATIBILITY SRAM RED® 22, Force 22 & Rival 22 Yaw™ front derailleurs/ Exact Actuation rear derailleurs

But they're both exact actuation as far as I'm aware so I can't see it not working. I've got rival 22 but never tried the Sram 1x groups, nevermind mixed them

It's a 2005/06 bike. External.

It's not really worth it. Maybe I could run newer shifters that have hidden cables with something like Nokon? Actually what is the go-to aftermarket cable these days? I think Nokon fell out of favour a bit.

It does depend if there's something wrong with the RD or the shifter too. If they're broken in some way then it's upgrade time. Or maybe I'll downgrade the DA to a newer Ultegra or something. Hmm.

Thanks but no thanks. Shimano-only.

thanks @slothy & @PhilDAS. Gonna go for it and see.

@slothy is right.
The details are hidden in SRAM blurb:
SRAM rival 22 shifters compatibility:
SRAM RED® 22, Force 22 & Rival 22 Yaw™ front derailleurs/ Exact Actuation rear derailleurs
SRAM apex 1 RD pull:
EXACT ACTUATION

Also I think I'm running a similar set up on at least 1 bike.

Yokozuna Reaction are the best if you don't have awkward cabling with tight turns.

This, very much the best.

Other option to reduced wear and tear is the Jagwire Elite Sealed Shift Kits, which allow the entire cable to be sleeved right to the derailleur.

How do they work with the existing cable stops? Do you drill them out or clip it / zip-tie it around them?
