  • Product not what is pictured
    Overall, very unhappy with my buying experience. I was having trouble finding the exact product number of the bottom bracket I was replacing. Then I saw this one! It looked the same, and when I looked closely at the picture, the part number was the same as the one I was replacing.
    When I received the product, it was something different, with a different part number and no spacer. I thought this was pretty poor.
    When I took the product to my nearest torpedo7 shop, they didn't have any of the (quite common) correct product in stock. They also flat-out refused to ship the correct part to my home, so i had to make a second in-store trip to pick it up. Yay online shopping!
