Lynskey GR260 with Ultegra Di2 50/34 chainrings and 11-34 cassette stock.
Sorry if this has been partially covered. I look some and didn't see anything quite like mine.
I switched to Absolute Black chainrings in the 46/30 size to get some more climbing ability. I then subsequently bought a power2max NGeco Rotor Aldhu power meter. When I bought the power meter I didn't realize the chainrings wouldn't fit the power meter. I'm looking at $240 or $790 paper weights. I'd like to have power so I have a few questions maybe some of the more knowledgeable folks here might be able to answer.
Why I did the things I did:
I wanted more climbing ability so switched to the 46/30 rings.
I bought the power meter that I purchased because I don't have clearance on my cranks (less than 10 mm between the Ultegra crank and the frame but much more on the Rotor crank) to fit a crank based pm and Power Meter City recommended p2m set up not realizing my chainrings don't fit. Now I can't return since it's been mounted, and I can't afford to try a different pm.
Questions:
Does anyone know what size cassette I can fit on the back with the 50/34 rings with no other modifications? 11/36? With the Wolf Tooth link, I think I could go to 11-40 or 11-42 but am not sure of that.
Is there anyone else that offers an 110/4 shimano chainring that gets to 46/30 that might fit on the power2max power meter?
If I were to take the Absolute Black rings to a machinist and remove the extra metal so it would fit a round spider, do you think it would be too fragile?
I could afford to buy a cassette if it isn't too expensive. I could afford to buy a road link, if it will work. I can't afford a new drive train, new cranks, new power meter etc. My wife is pissed and I'm done buying expensive new toys for my already expensive bike haha.
Or if someone has another good idea, feel free to offer it.
I have the RD R8050 GS derailleur. Jom doesn’t actually check this one and I haven’t seen anyone that has. 40 would be awesome if I could do it without spending too much.

awesome. Couple quick questions.
1. What cassette are you running? XT CS-M8000? I see one for sale for about $70.
2. Wolf Components has several different derailleur hangers to choose from. How did you decide to use the one that you did? Or do I need to just call them?
3. Do you think there will be problems with a 50/34 combo and the 11-40 cassette?

It's a shimano cassette, 11 speed 11-40, but I'm not sure of the model. Jensen has the M7000 for $50.
I also have a Lynskey GR260 with a similar Ultegra 8070 Di2 set up and front/rear gear ratios. I would love to have a 40-teeth in the rear for better climbing capability. Keeping watch on this thread.
I would skip the Wolf Tooth (not that they are bad, I use one on my road bike) and go straight to a SLX or XT derailleur. It can handle 42 teeth on its own. I am running the AB 46x30 with a 11-42 tooth Sunrace 11-speed cassette on my old wheels. Shifts better than anything I've used before, but to be honest, I've never before bought a new cassette, derailleur, chain and shifter at the same time. I put the entire chain on and it can actually shift onto the 46x42 (not that I do it) and it can run the 30 down to the 13 (not that I do that either). I don't even think about shifting on my rides anymore. The last shift from the 36 to the 42 sounds rough, but it has never failed.

i don’t want to get rid of my di2 rear derailleur. I’ve spent too much $$$ already and just need to get the least expensive option which is either the cassette or the Wolf Tooth Road link and cassette.

Post those absolute black rings up on eBay, someone will buy them and you can recoup a bit.
Funny you should mention that...someone on this thread already bought them. They shipped yesterday afternoon.

Remember that with e-tube/Di2 you have to have a front and rear derailleurs from road or MTB. No mix (road/MTB like front derailleur road and rear derailleur MTB) is allowed in the e-tube.
Update: I took my bike to The Bike Lab OKC and had them work on my set up. They updated my software, put on the new cassette, added the Wolf Link and added a longer chain (they didn't elaborate how much longer). It works great, but I'm keeping out of the 50 chainring and upper end of the cassette and the 34 and lower end of the cassette. But honestly, it's been very solid so far.
50/34 chainrings and 11-42 cassette seems to work so far.
You can put your Di2 into full Syncroshift mode and you will never shift into the wrong gears. There is no downside to this as you can still shift the front derailleur manually.

i’m sure that’s true but I can’t even remember how I check the battery level
