Description

INSIGHT MX4 2 Piece BMX Racing Crankset with Alloy Spindle.

All new for the young riders in BMX racing, an ultralight 2 piece Crank set, featuring a 4 Bolt Spider Arm with a 24mm Alloy Spindle Axle thats press fit into the crank arm. The Non drive side features a dual pinch bolt design to keep the cranks tight and running smooth, all the way to the podium!

Designed for younger riders who need a strong crank set up and want to move up to a 2 piece, 24mm axle crank with a 4 bolt spider pattern but need the shorter crank arm length.

With the lightweight Alloy Spindle, and a lower weight optional 4 bolt Chain ring, you can really drop the weight of your race bike!

Features

Takes any 24mm bottom bracket. Runs with press fit or Euro style threaded 24mm bottom brackets, sold separately, so it suits most race frames.
104mm four bolt pattern. The 4 bolt spider takes a 104 BCD chainring, including lighter alloy rings if you want to drop more weight.
Six lengths from 140 to 165mm. Choose 140, 145, 152, 155, 160 or 165mm, so younger riders get a short arm on a 2 piece crank.
Alloy spindle keeps weight down. The 24mm 7075-T6 alloy spindle is press fit into the drive side, with dual pinch bolts holding the non drive arm tight.
Rider weight limit 65kg. Insight rates the crank to 145 lbs, so check the rider weight before fitting it to a bigger bike.
