Query: Not for bikes with disc brakes

The only reason I am giving this a 1 is so hopefully people see that this only fits bike frames that do NOT have disc brakes. Unfortunately, this is not listed in the description of the product, it only states "fits all bike frames."However, amazon does sell the disc brake version of this bike rack, and I did a simple return through amazon to get the disc brake version, which fit perfectly onto my Cannondale.Great product, amazon just needs to update the product description.
