INSIGHT MX4 2-piece BMX Racing crankset with splined aluminum axle.
Brand new for young BMX racers, an ultralight 2-piece crankset featuring a 4-bolt mounting arm and a 24mm splined aluminum axle that presses into the crank arm. The non-drive side has a double-pinch bolt design to keep the cranks tight and operate smoothly, all the way to the podium!
Designed for young riders who need a solid crankset setup and want to upgrade to a 2-piece crankset with a 24mm axle and 4-bolt crown race, but need a shorter crank arm length.
With the lightweight alloy splined axle and a lighter 4-bolt crown mount (not included), you can really reduce the weight of your racing bike!

Questions fréquentes
What crank length should I choose for BMX Race?
Length depends on the rider's height: roughly 145-165 mm for youngsters (Mini/Expert) and 170-180 mm for adults (Pro). A three-piece chromoly or alloy crankset is the norm.
American, mid or euro bottom bracket: what's the difference?
These are the bottom-bracket standards. The standard must match your frame: check it before buying a crankset or a replacement bottom bracket.
Is shipping free?
Yes: shipping is free within mainland France from €99 of purchase. Below that, the cost is shown at checkout according to weight and the chosen shipping method.
Can I pay in instalments?
Absolutely. You can pay for your purchases in 2 or 3 instalments with Alma, completely securely. The option appears automatically at checkout.
How long do I have to return an item?
