if you unlock the first one (the one with some real power) then you just take the bike... the other one is just there to deter theft of the rear wheel, it's much more likely that one is cut than the u-lock, so it really doesn't matter what you link it to.

p.s. it's not the right track ends to be a fuji. i've seen them before but i can't place them quite yet.

edit* i change my mind, there is a tensioner throwing me off when i look at the ends. i still can't remember the ends i am thinking of though
