Hello, first time poster. I'm looking to buy a set of 29er wheels from a supplier that is both reliable and offers competitive prices - besides good wheels of course.... Looking at Carbon Speed and Yoeleo they charge high shipping fees and potentially even PayPal charges. When comparing to Aliexpress sellers many of these have free shipping on prices that are lower than the two mentioned companies. Is there a quality difference that I'm not aware of or what justifies $150 dollars more on a similar wheelset?
