Recently bought the Fantom Cross Uno from bikesdirect. I was putting it together and noticed the front hub has these little tabbed parts with screws that look like they are supposed to attach to the fender eyelets on the front fork. I guess this would hold the wheel onto the front fork in case you suck at tightening the bolts. Should I attach them to the fender eyelets? What are they for? Or should I just take them off?
