Exclusive to Spawn Cycles are what we think are by far the coolest cranks ever built for a kids' bike. The 6061 T6 cranks with a 4 arm spider come in annodized black finish with the updated Spawn logo (not exactly as pictured - they're better). A 104 mm bcd chainwheel fits these guys and you can throw them on a standard square taper spindle. Comes with 32t chainwheel and chainguard.
