DMR Sect 24" Custom Frame

The DMR Sect 24” Frame is our out-n-out trails and dirt jump frame – it’s built around a 100% heat-treated and double-butted 4130 chromoly tubeset to keep the weight down and strength up. We’ve been using 4130 cromoly to create frames for almost thirty years now, and we’ve built all that experience into every Sect frame we make.

The tapered head tube is light and stiff and allows the use of lighter and stiffer forks. The head angle is 69º – the magic number for stability at speed and easy rotation. You feel real safe spinning big jumps, as it’s not too twitchy – this is a frame built for going fast, and pulling up.

The front end of the bike allows enough room for barspins, and we made sure that you don’t have to move your feet, even with 175mm cranks and a 24” front wheel.

For the standover we wanted to show as little seatpost as possible without having the seat touch the rear wheel. This is purely aesthetic, but it makes a difference in the appearance of your build. It’s still super low for step-thru tricks and proper tables.

The rear end is obviously as short as possible, making the bike easy to spin and fun to manual and throw around. We’ve also added 3D graphics to the frame and 30 Year sticker kits.

Up front we have an investment cast tapered headtube, and out back it’s finished off with slotted taper-lock dropouts – there’s no need to run chain tugs and when your axle is tight, your wheel can never move in the dropout, no matter how big you case. All of this is built from DMR heat-treated, double-butted Chromo and weighs in at 2.37kg.
