Delivered in 3 weeks to Moscow. Despite it has been wrapped into antistatic(!) bag and padded envelope only it has arrived absolutely flat. Excellent chainring! High density aluminium alloy has been gently brushed, then slightly chemically polished. My sample has narrow teeth 1.97...1.99mm, and wide teeth 3.68...3.72mm width. Main plate is 3.94...3.96mm thick. Bolt circle is exact and perfectly matches my Shimano S501 system with 11/128" chain. I friendly recommend to use this chainring in 1x(9-11s) "super narrow" drivetrain' set up... Of course I do like the neat laser engraving on the chainring. That was the main reason of purchase one from WUZEI; in my opinion other Chinese manufacturers do too many laser engraving on their products. Respect to WUZEI, and many thanks to the seller.
