I agree about the flex in the rack, but the price is right and I do haul a lot with that rack. I was blaming the bike for the wiggle but I can see it being the rack. My son has a topeak with straps but never really carries a big load.My nice racks arrived today and all I can say is WOW. In my opinion they are worth the $108 my lovely wifey paid at bike island. Not my money though
