Shimano di2 groupsets from aliexpress

[kurtkowal]

Has anyone bought an ultegra chain on ali? Just a chain not a full groupset. I know it's full of fakes but does someone have a good experience (with competitive price?)

As long as you buy from a reputable store (like anrancee) you should not have any problem.

I bought an 105 group from anrancee and the chain seem to be genuine. I'm not 100% sure as i dont have another SLX chain to compare it to.
As i sidenote why not buy the chain from an established retailer? In this case im not sure the price diference is worth the risk of buying from Alix and chains are probably the easiest main component to fake

At least here in Chile It's much more expensive to buy from retailers (just one company has the representation of shimano), plus the availabilty ain't the best.

I was in chile a couple of weeks ago, I was impressed by the number of people biking especially in Santiago and in the cajon de maipo Valley!
You guys have such a beautiful country and people are so welcoming!

My Ultegra Di2 just arrived today, bought on AliExpress. The shifters don’t turn on at all — I even replaced the batteries just to be sure. I’m starting to suspect these might not be the wireless ST-R8170 levers they were advertised as. The internal mechanism also looks different, more like a mechanical unit. If anyone has experience with this or can tell me more from the photos, I’d appreciate it. I’m also open to any tricks or checks I might try to get them working.

Should be an LED. If you push both buttons on the lever for a few seconds does the LED turn green?

yes the right turn green you are right! the left seems dead, but it is already something. did not about the both buttons. thank you

You can try to connect the leaver to the main battery using the wires provided. That way you can at least tell if there is a problem with the CR batteries/connectors or with the leaver itself.

yes using the wires it works, as I have also changed the CR batteries I think the problem is in the connection between the CR batteries. There is a problem but at least is not a fake useless...thank you

I always buy from Amazon and watch this video before opening the cellophane wrapper.

In the description, is it the R8170 levers or 8150 ? Normally, you should have QR code on R8170 to pair with the apps.

I got this for my last build https://it.aliexpress.com/item/1005005766195381.html no issue at all after 1+ year and all original

[FrostedDyslexia]

anyone ordered a groupset from ali recently?

after reading through this thread, I guess the best option is to pay slightly more shipping fee for UPS express saver method so they handle customs for you..?

also wondering if there are any bigger alix sales expected to come before black friday.

I upgraded my 105 with Ultegra RD/FD already running Ultegra cassette and chain.

IMO it feels a lot nicer than the 105 but apparently that's a placebo. (My issue with 105 was I constantly had to re adjust FD and it's a breeze to setup through etube since no H/L limit screws had the whole upgrade done in 20mins?)

it was ~$300 AUD cheaper than local so couldn't help it.

The R7150 RD+FD shifts exactly the same as R8150. The motors are the same.
