Still thinking of marketing here, "premium" products that are not premium.
IRD freewheels - $80. I have one here. Had it apart. Not impressed. Pawl springs are way too strong, causing excessive friction even with the lock ring loose! Proven track record for QC issues. I get the gear range thing, but if a Shimano or Sunrace freewheel is $13, this one is worth less and nowhere near $80.
