Component Deals & Selection / Re: Shimano di2 groupsets from aliexpress
« on: June 06, 2025, 03:39:30 AM »
It is the 12s 105 di2 groupset that I got, and it included the brake calipers.
With the Magene PES 515 crankset, the ZTTO steel cassette, an KMC waxed chain and some rotors (I prefer the MT-800 as I don't like experimenting with brakes, but there might be cheaper non-Shimano solutions) you have a complete groupset which is almost the same weight as an ultegra di2 groupset yet includes a spider powermeter and is still cheaper compared to a complete ultegra groupset.
I do not have any experience with Ltwoo or other Chinese group sets, but from reading in this forum it appears to me that shimano in 2025 is still the more reliable option.
Warranty is definitely a disadvantage when you get your parts from AliExpress. I never needed the warranty so far, but I would guess that you do not get a replacement in case of an early failure, so that is what you have to accept (and what actually makes not only the group sets but also the frame sets cheaper when you buy them directly from China).
