Sect Custom Frame

The DMR Sect 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 spinning. You feel real safe spinning big jumps, not too twitchy.

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

For the standover we wanted to show as little post as possible without having the seat touch the rear wheel. This is purely aesthetic but 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. It’s finished off with taper-lock dropouts – no need to run tugs and 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.

The DMR Sect frame – from the trails, for the trails.
