Yeah, this one should work.
I bought this adapter 2x times already and no issue:

So just for your information, since I did not find much online about this topic regarding larger chainring setups with a difference of 16+ teeth:

I went with Ultegra Di2 and a 54/36T chainring combo. Shifting works really well. I cannot directly compare it to a 52/36 setup, as I had mechanical Ultegra on my old bike and I am also using off-brand components (casette, chain, chainrings).

I am happy with the setup and would recommend it to anyone considering a bigger chainring.

Note: I am using an extender on the front derailleur.

Hello everyone,

I finished my build. I am really happy with the bike and can't wait to take it for a proper spin. The weight is 6.9 kg with pedals, bottle cage holders, sensors, Garmin mount, etc.

I will probably slam the stem in a few months.

I am still looking for some lightweight budget thru-axles, so if anyone has a recommendation, let me know.

If I remember correctly. The headset supplied by LTK is a low-cost generic headset used by a number of low-priced Chinese frames, as it offers a couple of different C-Ring fitment options.

Given that this frame has an 8.7mm bore depth, you can fit your choice of FSA, Deda, Cane Creek, etc., upper bearings, as long as you use the correct 52mm (or 51.8mm) x 40mm x 8m 36/45-degree lower bearing; you should use those. It will minimize the need to replace the headset bearings in the future, and the track record for these generic headsets is really bad in terms of fit and preload retention. I personally recommend the FSA No55R LS, but I am happy to assist if I can. Some parts come with C Rings and covers, and it can be more cost-effective if you ask around first.

For example, if you are buying Deda Superbox V2 stem, it comes with a C Ring and headset cover, so all you need are the correct bearings: 52mm (or 51.8mm) x 40mm x 8m 45/45-degree upper bearing and a  52mm (or 51.8mm) x 40mm x 8m 36/45-degree lower bearing.

FSA ACR No.55R
Would this one work? It says upper: 52mm x 42mm x 7mm  45/45 and lower: 52mm x 40mm x 8mm 36/45

Has anyone had trouble getting the headset tight? Should I have used the crown race?

Yes, I am having trouble as well. I am using the two bearings that were delivered with the frame etc., along with the C-ring that came with my handlebar. I still have a bit of play.

I think my compression plug might be sitting slightly too high, so I will cut the steerer tube a bit shorter and see if that fixes the issue. If not, I will get the FSA No.55R, which is recommended here in the sub by several people. It is just annoying that I have to reroute everything through the handlebars again, but yeah, what can you do.

You do not need to use the crown race that came with the headset, I think it is unnecessary.

Otherwise, have a look at this post to identify the issue

I have the Li-ning Feidian Challenger 5 as well and did around 200km in them. Likem too, it's my first chinese running shoe tho.
I ordered Dynafish Xiaonian and Qiaodan Feiying PB 6.0, they should arrive this or next week.

It's official now, they sent a newsletter out.

Hey,

good to see people are interested in this power meter + crankset as well. Unfortunately, I'm still waiting for my frame and the remaining parts to build my new bike, so I'll only be able to review/test the power meter at the end of December or the beginning of January. Sorry about that.

I just checked on Google real quick — there's some more/new information about the ArcRayo, but still no real reviews. Besides that, there are a few other new cheap power meter brands popping up right now like Thinkrider, Leoseek, Geoid, etc. Those might be good alternatives as well.

RYET's scare me after watching this CADE video:

Yeah, fair point — I heard about those exploded rims etc. too, but that was like 2–3 years ago. It's not unusual for Western brands to have recalls either, but at least you get proper warranty support with them. A lot has changed in the industry since then anyway, even for brands like elite wheels etc.

I haven't owned any Ryet wheels myself, so I can't really say much about them. They're definitely in the budget category, but spec-wise they look pretty solid for the price these days. I get why people are still a bit cautious about the quality though. Need some decent up to date reviews about their products/wheelsets.

I see, good on you!

Yes sir, although I really only need another wheelset and crankset.
I'll decide last minute if I should get another Magene P515, because even though it has proprietary mounts, at some point I will have all crank lengths anyhow haha. But the ArcRayo/Zrace combo looks really sweet as well.

Yeah, sweet. I was planning first to get the Magene TEO 515. I have already a Magene powermeter on another bike. But got the good deal in the end.

I'm looking for a wheelset as well. What are you going for?

220CHF?! So 240€ - that's crazy cheap, even the current 11.11 deal does not come close. How did you manage that?

I think I got lucky — it seemed like a promo because the item was newly listed in the store. After I made the purchase, only the other crank length options were still available at the discounted price. So what I mean is that there was only one item per setup (crank length option + power meter) available at the discounted price. I still haven't tested it tho. Ordering all the other parts now with the 11/11 sale for my new bike build.

Are you getting sorted for your new build as well?

I am noticing that the price difference between buying on AliExpress and locally (in the UK) is not so much! I only just started shopping for an Ultegra 12 speed Di2 full groupset, and I do not know what prices were like earlier this year.

I can buy for 1057GBP +35GBP shipping from anrancee and risk additional customs tax. Compare this to local UK price of 1175GBP with free shipping and no added tax.

For me, the prices are really good in the Anrancee Store. I'm based in Switzerland, and the Shimano R8170 ULTEGRA Di2 Electronic Part (upgrade kit) costs 800 CHF / 992 USD including shipping (without coupons). With coupons, I can save another 98 CHF, so the total comes to around 700 CHF / 868 USD for the Shimano R8170 ULTEGRA Di2 upgrade kit.

The Shimano 105 R7170 Electronic Part Groupset (FD R7150) comes to about 520 CHF / 645 USD in total.

That's roughly 200–400 CHF cheaper than buying it here or from Germany.
I contacted Anrancee support, and they confirmed that they can adjust the declared value on the parcel for me, so I'll have no import tax or a very low one. Support was really helpful and made the items for me available to order from Switzerland. Beforehand I couldn't find the groupsets because shipping to Switzerland was not available and I was only able to see them over the direct link.

However, I agree with what others have said — if you have any issues with the groupset, you probably won't be able to claim warranty, which is the major downside.

Have 53/36 with Ultegra Di2, shifting feels the same as 52/36. Front shifting was never an issue for me with Shimano.

Oh sweet, that's good to know. Do you know if there's a big difference between the 105 and Ultegra front derailleurs? Some websites say the Ultegra can handle up to 54T, while others list it as only compatible with 52T. Did you have to use an extender on the FD to make it work?

Did you guys find any good offers for the 11/11 sale? I had a look but there was not much price difference... . At least there will be the codes. Just checking because in the past I was not able to find all the offers with the search function.

You'll be pushing beyond the 16t limit and your front shifting might be compromised. I was in a similar situation looking to go with a bigger chainring on one of my road bikes, but I opted to swap out my cassette to an XDR 12 speed cassette. You'll have to swap out your freehub and use something like a KMC X12 chain (Shimano/SRAM cross compatible), but it's an easy way to keep your front 2x chainring intact and get slightly higher top end on the descents and quick speed bursts on the flats. Both my road bikes are using 50-34t and 52-36t chainrings and I settled on using 10-33t on all my wheelsets. I try not to use the 10t often, but it's good to have when you need additional speed. You can either go with SRAM's XDR cassettes or use Goldix XDR cassettes off of AliEx.

Thanks for the reply; that's definitely an option I should consider. I'm building a new bike and haven't chosen a wheelset yet, so an XDR hub would be possible. The only downside might be chainline alignment, which could result in higher friction and potentially increased wear.

I'm also a bit concerned about the 16T limit—as well the Shimano 105 Di2 maxes out at 52T. But I think with a front derailleur extender, a 54T chainring should be fine. Let's see if anyone has tried it out. Did you find much information online when you were checking for your setup?
