Pretty much a staple in the BMX world since about forever, the Truvativ American To Euro BMX BB Adaptor lets you ditch the heavy one-piece crankarm for the lighter and more efficient spindle and bolt-on "Euro" standard. In this case, Euro means a crank set-up like just about every other bike you might have. It's a must for BMX bikes that still have that larger BB shell - recognizable by the one-piece crank it contains. Suitable for nearly all one-piece crank bicycles, from classic Schwinns to "department store" bikes.
