Machined from 7075 aluminum and including multiple bolt lengths with matching nuts, this kit provides a lightweight alternative to steel chainring bolts while accommodating various chainring and crank configurations.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e7075 aluminum construction\u003c\/strong\u003e – High-strength aluminum alloy provides durability at reduced weight compared to steel bolts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMultiple bolt lengths included\u003c\/strong\u003e – Kit contains both 8.5mm and 6mm front bolts to fit different chainring and spider thicknesses\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e5mm rear nuts\u003c\/strong\u003e – Matching rear nuts work with both bolt lengths for secure attachment\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal compatibility\u003c\/strong\u003e – Fits cranks with threaded chainring bolt holes and those requiring separate nuts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLaser-etched logos\u003c\/strong\u003e – Permanent laser-etched branding won't fade or peel over time\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 7075 aluminum alloy, CNC-machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit contents:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eFive (5) x 8.5mm front bolts\u003c\/li\u003e\n\u003cli\u003eFive (5) x 6mm front bolts\u003c\/li\u003e\n\u003cli\u003eFive (5) x 5mm rear nuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 7g complete kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Anodized with laser-etched logos\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt count:\u003c\/strong\u003e Five-bolt pattern (standard for most BMX chainrings)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eCompatibility and Ideal Use Cases\u003c\/h2\u003e\n\u003cp\u003eThis kit fits standard five-bolt chainrings and cranks—the most common configuration for BMX and single-speed drivetrains. The dual bolt length options (8.5mm and 6mm) accommodate different chainring and spider thickness combinations. Use the appropriate bolt length based on your specific chainring and crank setup—measure the total stack thickness (chainring + spider or crank arm) to determine which bolts provide proper thread engagement without bottoming out. The rear nuts work with cranks that do not have threaded chainring bolt holes, while cranks with threaded holes can use the bolts alone.\u003c\/p\u003e\n\u003cp\u003eBest suited for weight-conscious riders who want to reduce drivetrain weight without compromising chainring security. The 7075 aluminum construction saves grams compared to steel bolts while maintaining adequate strength for BMX applications. \u003cstrong\u003eImportant: Aluminum bolts require careful installation—use appropriate torque and avoid overtightening, as aluminum threads can strip more easily than steel.\u003c\/strong\u003e Apply anti-seize compound to threads during installation to prevent galling. Check bolt tightness periodically, especially after initial installation, as aluminum may settle differently than steel under load. Ideal for racing applications where every gram matters, or for riders who prioritize lightweight components. Not recommended for riders who frequently remove and reinstall chainrings, as repeated tightening can wear aluminum threads—steel bolts offer better durability for frequent maintenance.\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.
