Featuring forged 6061-T6 aluminum crank arms with a press-fit 7075-T6 alloy spindle, this crankset uses a 104mm BCD four-bolt spider pattern for chainring mounting. Available in six crank arm lengths from 140mm to 165mm, it provides sizing options for growing riders while keeping weight low through aluminum spindle construction.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eForged 6061-T6 Aluminum Crank Arms\u003c\/strong\u003e – Forged construction increases material strength and durability compared to cast cranks while maintaining lightweight design\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e24mm Alloy 7075-T6 Spindle\u003c\/strong\u003e – Aluminum spindle reduces weight compared to chromoly steel axles; press-fit into drive-side crank arm with dual pinch bolts securing non-drive side\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e104mm BCD Four-Bolt Spider\u003c\/strong\u003e – Standard bolt circle diameter accepts lightweight aftermarket chainrings for further weight reduction and gearing customization\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Pinch Bolt Non-Drive Side\u003c\/strong\u003e – Two-bolt clamp design on left crank arm ensures secure attachment to spindle and prevents loosening during racing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSix Crank Length Options\u003c\/strong\u003e – 140mm, 145mm, 152mm, 155mm, 160mm, and 165mm lengths accommodate different rider heights and leg lengths\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e160mm Q-Factor\u003c\/strong\u003e – Spindle width provides standard BMX stance width for optimal pedaling biomechanics\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCrank Arm Material: Forged 6061-T6 aluminum\u003c\/li\u003e\n\u003cli\u003eSpindle Material: 7075-T6 aluminum alloy\u003c\/li\u003e\n\u003cli\u003eSpindle Diameter: 24mm\u003c\/li\u003e\n\u003cli\u003eCrank Type: Two-piece with press-fit spindle\u003c\/li\u003e\n\u003cli\u003eBCD (Bolt Circle Diameter): 104mm\u003c\/li\u003e\n\u003cli\u003eChainring Bolt Pattern: 4-bolt\u003c\/li\u003e\n\u003cli\u003eNon-Drive Side Attachment: Dual pinch bolts\u003c\/li\u003e\n\u003cli\u003eQ-Factor: 160mm\u003c\/li\u003e\n\u003cli\u003eAvailable Lengths: 140mm, 145mm, 152mm, 155mm, 160mm, 165mm\u003c\/li\u003e\n\u003cli\u003eColor Options: Black with black laser-etched graphics | Black with silver laser-etched graphics\u003c\/li\u003e\n\u003cli\u003eWeight: 140mm (550g \/ 19.4oz) | 152mm (568g \/ 20.0oz) | 155mm (573g \/ 20.2oz) | 160mm (585g \/ 20.6oz) | 165mm (593g \/ 20.8oz)\u003c\/li\u003e\n\u003cli\u003eRider Weight Limit: 145 lbs (65 kg)\u003c\/li\u003e\n\u003cli\u003eBottom Bracket: Not included (requires separate 24mm BB—press-fit or Euro threaded)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eCompatibility and Ideal Use Cases\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eCompatibility Requirements:\u003c\/strong\u003e Requires a 24mm bottom bracket (press-fit or Euro-style threaded). Not compatible with one-piece cranks, 19mm spindle systems, or other axle diameters. Verify your frame's bottom bracket type before purchasing. Compatible with 104mm BCD four-bolt chainrings.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003e This crankset has a maximum rider weight limit of 145 lbs (65 kg). Riders exceeding this weight should use cranks rated for higher loads to avoid potential failure.\u003c\/p\u003e\n\u003cp\u003eDesigned specifically for younger, lighter BMX racers who want to upgrade to a modern two-piece 24mm crankset without the weight of full-size chromoly spindle systems. The aluminum spindle and forged arms keep weight low, while the 104mm BCD spider allows use of lightweight aftermarket chainrings for further weight savings. The range of crank lengths suits growing riders from beginner through intermediate racing levels. Best for riders under 145 lbs who are ready to move beyond entry-level one-piece cranks but don't yet need the heavier-duty construction required by larger, more powerful riders.\u003c\/p\u003e \u003cdiv\u003e\u003cp.\u003e\u003ci\u003e\u003cu\u003e\u003cfont size=\"2\"\u003e\u003cb\u003e\u003c\/b\u003e\u003c\/font\u003e\u003c\/u\u003e\u003c\/i\u003e\u003c\/p.\u003e\u003c\/div\u003e\u003cdiv style=\"\"\u003e\u003ci style=\"font-size: 0.875rem;\"\u003e\u003cu\u003e\u003cfont size=\"3\"\u003e\u003cb\u003e\u003cbr\u003e\u003c\/b\u003e\u003c\/font\u003e\u003c\/u\u003e\u003c\/i\u003e\u003c\/div\u003e\u003cdiv style=\"\"\u003e\u003ci style=\"font-size: 0.875rem;\"\u003e\u003cu\u003e\u003cfont size=\"3\"\u003e\u003cb\u003e**Due to unique nature of this item, ALL sales of this product are FINAL.
