The main thing is that different cranks were sent to me: one 170mm left and another right 175mm, at first I tried to close the question directly with the seller. He wanted me to send him one of the cranks, and then he will send me another. I tried to reason that I did not want to do shipments all summer, but it didn’t work, then I opened a dispute. In short, they returned $ 60. This, of course, is not enough to order new ones. I ordered another products from this seller, and everything was in order. I advise the seller, he is oppressing his line, but honestly and generally a lot of positive reviews, I just had a little luck and I got an error. It’s just that some garbage came out... Something like this... Despite everything, I advise the seller.
It took a while to arrive because of COVID-19 delays. The packaged arrived damaged, but thankfully the product was not damaged. It is just what I had hoped for and works great.
