Carefully machined from 6Al-4V "Grade 5" titanium and featuring a novel split lattice design, these crank arms have an incredible strength-to-weight ratio. Each crank arm weighs just 219g/7.7oz. Although there are lighter crank arms on the market, fatigue and impact testing at ACT Labs in Long Beach, CA showed that these crank arms in particular remain durable even as titanium spindles and standard BMX pedals begin to fail. What this means is that after repeated abuse, you'll more likely need to replace your spindle, bottom bracket bearing, and/or pedal long before you'll need to replace one of these crankarms. You can read all about the initial development of these cranks on our blog, and watch a mashup video of crank testing on our youtube
