NRS LoPro Frame Fittings

Key Features

Hot-Forged Construction: Forged 6061-T6 aluminum is stronger and lighter than cast fittings.

Streamlined & Lightweight: Redesigned to be 25% lighter while maintaining superior strength.

Universal Fit: Designed for 1 5/8" OD frame pipe; crossbar pipe must have 1.38" inside diameter.

Superior Holding Power: Molded ridges on the gripping surfaces increase torsional strength—ideal for casting platforms, thigh bars, and more.

Product Details

Forging aligns the metal’s crystalline structure for greater durability and performance under stress.

The hollowed shank and slimmed-down profile reduce weight without sacrificing functionality.

Recommended for use with official NRS frame pipe or verified 1.38" ID pipe only.

LoPro fittings are crafted in-house at the NRS Frameshop for precise fit and finish.

Note: When fabricating custom frame parts, metalworking skills and proper tools are strongly recommended.

Anti-seize is advised when using stainless steel hardware to prevent galling during installation.
