48 Spline cranks like Profile Racing require a tool to pull the crank arms on or off of the axle. The Flight Arms just slide on to the Flight axle. Redline cranks install fairly easily once you get the cups and bearing pressed into your frame. If you are looking to build a retro BMX Racing bike then these Redline Flight Cranks will be an excellent choice. The Redline Flight SX Version has the red and white retro crank arm stickers and no other difference other than costing us more. We may have the matching black Flight sprocket too.

These are Redline double pinch bolt style bmx cranks. This crankset includes, chrome Redline Flight crank arms, Redline 19mm spindle, optional Redline sealed bottom bracket, Redline axle nuts and all the Redline hardware is included.
