So here's my followup on the Thinkrider X2 i ordered for my brother. The price was 277,69€ using a choice day coupon. Shipping took only four days from Madrid to my address in germany. The parcel wasn't damaged or anything and the trainer was well packaged. I was actually surprised by the fact that there was an english manual. All the necessary adapters for through axle or quick release are included. The only thing that seems a little cheap is the power supply. If i compare it's weight to the one of my kickr core i can't imagine it will be the same quality. So if i had to guess one thing that will fail on this thing it's the power supply but that should be replaceable fairly easy. Apart from that the build quality looks and feels solid. The base is attached by four screws and seems solid. I calibrated the trainer using the Thinkrider app which worked like on the kickr.
I did two rides on the trainer, one relaxed zone 2 ride in erg mode and one ride up alpe du zwift (on 50% trainer difficulty). The only real difference i noticed between the x2 and my kickr core is that the x2 leans slightly more to left and right, which isn't a bad thing in my opinion. ERG mode was really smooth and the resistance adjustments were fast. Resistance up alpe du zwift also seemed realistic.
This is absolutely not an in depth review, i just did some test rides before my brother picked it up. But so far it really felt like a great alternative to the kickr. With the right deals you can get it for half the price of the kickr which is insane. The only questions are longevity and warranty if something fails, only time will give answers to these. Apart from these two questions it's a great cheaper alternative to the kickr core. I kinda regret not going for the x2 myself and saving 230€.
If you have any questions feel free to ask. If my brother faces any issues with the device i will let you know here.
