The Saris Bones Knob is the OEM replacement knob for the Saris Bones 2 and the Bones 3 bike racks.
During a move, three of our Saris Bones Two Knobs got lost. The ones we received from ACK were perfect quality and did the trick. Other places I looked, including the Saris website, came six in a pack and were more expensive. The ability to buy only what is needed, the inexpensive price, the fair shipping cost and the Saris quality made this a great purchase!
This replacement Saris Bones Knob is wonderful! I bought a used Saris Bones bike rack and two of my knobs were stripped. I ordered these replacement knobs and they fit/worked perfect! Thank you!
