SECT Dirt Jump Frame

The SECT 26” Custom is our purist dirt jump bike frame.
Its geometry is built around steeper, faster trails and bigger tricks.


Every part of the bike has been re-thought, from front to back;

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, we made sure that you don’t have to move your feet, even with 175 cranks. For the stand over 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. Its still super low for can tricks and tables.

The rear end is obviously as short as possible, making the bike easy to spin and fun to manual and throw around. Its 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.

This dirt jump bike frame is built from DMR heat treated, double butted Chromo and weighs in at 2.37kg.

8 of the best dirt jump, pump track and slopestyle mountain bikes for 2020

“British company DMR pretty much invented mountain bike dirt jumping – or, at the very least, has been around since its earliest moments. And it’s no surprise that it’s still going strong – the Sect is one of the most popular frames for dirt riders".

“The Complete DMR Sect Pump and Dirt Jump Bike uses the same legendary dirt geometry as found on our DMR Sect frame, including a super short rear end for spins and flips, 69º head angle for stability, great toe clearance for barspins and low standover for tailwhips.” – DMR.
