Luftalarm: Go Big... it is OK... it’s the motto! Our BMX jump crank is designed for high-impact loads. Forged out of AL-7050-TV, the Luftalarm is lighter than a hollow Chromoly crank. The Luftalarm features an easy to replace full CNC’d 6.35mm 7075 ring and Bash Guard. The ISIS Drive GigaPipe BB will give it strength and an easy to service crank-BB assembly.
