i am planning on purchasing a new crank from danscomp.com (poverty pow 3pc crank) and i am not sure which crank to buy. they are all 175 mm which im pretty darn sure it will fit my bike but it gives u the option of american bb, euro bb, spainish bb, or mid bb. i just dont know which one aplies to my bike. i think it may be american. under my bottom bracket there are some letters and numbers and i was thinking that might be my answer. can you help me?
