Dura-Ace R9200

[pdlpsher1]

Guys, has anyone tried to use a 9100 series 50/34 crank with the 9200 series? I have everything I need to change over to the 9200 except for the 50/34 power cranks, and it's unclear when those will arrive. I already have 9100 power cranks, so if those work as an interim solution I can just go with them until the 9200 power cranks arrive.

The pros (and many non-pros) are using the 9100 crankset along with 9200 without issues due to the supply chain shortages.

GP Lama recently reviewed the 9200P power crank and the results were not good. There are better options out there. See ipenguinking's P2M setup on the previous post. 9200 rings are hard to find right now so you could use 9100 rings on a P2M without issues.

How's the chain length at big-big, 50f-30r? I think the rattle got worse after tightened the 'b gap' and shortened the chain. The chain was very slack and hitting the chain stay after tightened the b gap therefore I had no choice but to cut the chain by 1 1/2 link. I think expereriencing diff chain length and b-gap is my next step.

Your chain length looks OK. Chain length and the B-gap are inter-related. You could try widening the B-gap and see if the chain resonance issue is better. Find the gap that minimizes the resonance. I doubt you'll notice any differences in shifting quality at various B-gap settings.

ps Nice bike!!!

Will the P2M work with the Shimano 9100 BB I have now? Or will that have to change?

If you want the lightest weight possible you'll want the Aldhu Carbon arms, which can only be mated to a 30mm aluminum axle. You will need a new BB for the 30mm axle. P2M also offers the aluminum Aldhu arms which can be used with a 24mm steel axle. In which case you won't need a new BB.

Got it. Is there another brand with similar accuracy and performance that won't require a BB change? I got the expensive Ceramicspeed BB and would prefer not to have to ditch it. But will if necessary.

SRM Origin will allow you to choose the 24mm axle (steel or titanium) and would allow you to keep the existing BB.

It was said million times here, yes, works like a charm.

No spacers or anything? Just plug and play?

Red DUB arms are both lighter and cheaper

Thank you for the help. I really appreciate it. Do you know the best place to buy this crankset? Seems like the lead time for carbon arms may be really long? Like 20 weeks.

[pdlpsher1]

So you're upgrading the Aethos and not the F12? You spoke about changing the AXS over to 9200. In that particular case you can get a Quarq DFour DUB without having the change the BB. But if you are going from 24mm axle to a DUB or 30mm axle you'll need a new BB. DFour is a fine option. There's will be a minor cosmetic mismatch as the DFour DUB is cosmetically designed for 9100 rings not 9200 rings. P2M don'thave the cosmetic ridges but there still will be some mismatch as the Shimano rings have ridges. Quarq, P2M, and SRM are all fine choices, and much better than 9200P. Personally I like P2M for their modular design. The crank arms themselves can be detached from the axle. If the axle gets damaged I could replace it. On the DFour the axle is pressfit into one arm. P2M comes with two battery choices, rechargeable or CR2450 coin cell. The one with rechargeable option is slightly lighter but more expensive. P2M can be bought directy from their N.A. headquarters. Shipped duty free and free shipping from Vancouver BC. SRM is fine too but more expensive than either Quarq or P2M. I hope this helps.

Can anyone advise on what the verdict is on the new brake calliper clearance compared to 9170?

I just got a Factor Ostro built up on a 9170 groupset and already running into rubbing issues. Wondering if it's worth upgrading the callipers for the extra brake clearance?

Can anyone shed some light on this? Are they much of an improvement in terms of clearance?

So again, yes, yes, yes, no marketing, yes.

Can you have 12s shifters and calipers on 11s gears?

----

Can't find anything online or in the forum,

Wondering if you guys have any idea of the Newer 12 speed BR-R9270 calipers will work with the old 11 speed dura ace levers?

Can't see why not..?

Anybody tried this?

Yes, it is working very well, for example in one of my bikes.

Here you have many information about it from other people.

And it is not marketing, bigger space for rotors truly exists.

After spending last 30min playing with the bike on the repair stand, I can confirm the chain is hitting the tab on the RD cage no matter how I adjust the b-gap. It happens on the last 5 gears when I'm putting torque on the crank. I can see the cage moves then the chain jumps and kisses the tab when I apply torque to the crank. I have exactly same experience when riding outside as the rattle only happens on a climb or when I change the cadence abruptly. I can only widen the b-gap by 15mm before the chain starts jumping on big-big. (chain too short) Maybe I should hot have shortened the chain last week? Here are the questions for fellow weightweenies?

1. Can I add links to the exisiting chain? I'm more than happy to buy a new one but M9100 chain is backorder in the US for weeks. But start a new chain and play with the b-gap might not get me anwyere.
2. When happen if I grind the tab off? i don't think the chain will fell of the pulleys during the ride, right?
3. How about switching to those fancy OSWP from Kogel or Ceramicspeed? I don't see those with a tab on the cage.

I'm giving the SRAM drivetrain on my F12 one more shot with the Chain Spotter. It's much cheaper than buying a whole new drivetrain.

However, I've been putting together the parts to upgrade my Aethos to 9200 for a few months. The cranks are the last piece. I may just go for the SRM option. Looks nice and no new BB needed. Seems to me that the Look carbon cranks are just fine. They have lighter/stiffer cranks, but the lead time is 20 weeks. I suspect with a 24 mm Ti spindle the crankset will shave weight off the 9200 anyway.
