DMR SECT 24" Bike Frame

Premium 4130 chromoly construction: 100% heat-treated, double-butted tubing for high strength and low weight, ideal for dirt jump abuse.
24”-specific DJ geometry: Purpose-built small-wheel geometry for quick spins, tight rotations, pump-track speed and flickable handling.
Perfect DJ head angle – 69°: Balanced for stability at speed, confidence in the air and predictable steering.
Optimised front-end clearance: Designed to avoid toe overlap and maximise space for bar spins, X-Ups and technical tricks.
Low stand over height: Clean aesthetics with maximum manoeuvrability for step-throughs, tables, whips and more.
Slammed rear end + Taper Lock dropouts: Ultra-short 390mm stays with patented dropouts that lock the wheel solid, no tugs, no movement, ever.
Rider-designed, rider-refined: Developed by the DMR team using decades of dirt-jump experience.

The DMR Sect 24” Frame is our pure trails and 24-inch dirt jump frame, built from a fully heat-treated, double-butted 4130 chromoly tubeset for the perfect blend of low weight, high strength and classic chromo ride feel. After nearly 30 years of crafting chromoly frames, every bit of that heritage feeds into the Sect making it one of the most capable small-wheel DJ frames on the scene.

A lightweight, stiff investment-cast tapered head tube keeps steering precise and allows the use of modern, lighter forks. The frame runs our signature 69° head angle the sweet spot for DJ riding, stable at speed, predictable on take-off and rotation, and confidence-inspiring for big tricks. It’s fast, it’s composed, and it’s never twitchy.

The front end provides ample clearance for bar spins, X-Ups and crank-heavy tricks, even with 175mm cranks and a 24” wheel. The low-slung stand over keeps your build looking clean, with minimal seatpost showing, while still giving plenty of room for step-throughs, tables and whips.

Out back, the slammed 390mm rear end delivers the tight, responsive handling a 24” jump frame demands quick rotations, poppy manuals and effortless bike control. New 3D graphics and optional 30-Year sticker kits give the latest Sect frame a fresh, modern finish while staying true to its DMR roots.

At the rear, the patented Taper Lock dropouts eliminate the need for chain tugs entirely once tightened, the wheel simply cannot slip, even on heavy cases. Combined with DMR’s heat-treated chromo construction, the Sect 24” frame comes in at just 2.37kg.
