Redline Flight Cranks 3pc chrome BMX

These are the real Redline Flight Cranks 401 with a optional bottom bracket. You pick your bb size for your frame style. 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. These are Redline double pinch bolt style bmx cranks. Note: The pictured American BB fits most all the old school frames from the 80s and early 90s. A bottom bracket cup press tool (Park HHP-3) helps to press in the cups and bearing into your frame. Fits 9/16″ pedals only. We may have the matching black Flight sprocket too.

The Redline Flight SX Version has the red and white retro crank arm stickers and no other difference other than costing us more.

If you are looking to build a retro BMX Racing bike then these Redline Flight Cranks will be an excellent choice. Redline cranks install fairly easily once you get the cups and bearing pressed into your frame. The Flight Arms just slide on to the Flight axle. 48 Spline cranks like Profile Racing require a tool to pull the crank arms on or off of the axle. Profile crank arms will become easier to push on and off once they are pulled on and off a few times. Profile Cranks are American made and do require more mechanical skill to install than Redlines.

See all the options. ACEBMX makes it easier to order by adding several options for the parts you will likely need, all in one item listing! How do we know what you need? We have over 30 year experience!
