The DMR Sect two-piece MTB cranks combine bombproof trail strength with the confidence-inspiring build of a race-ready enduro crankset — engineered for riders who demand affordable performance without compromise.

We have paired proven 6061-T6 aluminium crank arms with a super-tough, hollow heat-treated chromoly crank spindle to create the new Sect cranks. The forged crank arms have a sleek shot-peened finish and come in two sizes – choose from either 165mm or 170mm crank arm lengths.

The chromoly spindle comes in a 24mm diameter – oversize and strong for the trails, featuring a standard size to fit the majority of bottom brackets. Complete with a SRAM Direct Mount 3-Bolt chainring interface, this ensures easy-fit installation, a wide choice of suitable chainrings, and simple maintenance. Fit and forget.

The whole set weighs in at 675g for arms, axle, and hardware. We also included two sets of bolts and spacers, giving you the choice of running Boost 52mm or Standard 49mm chain lines, so it’s compatible with the majority of bike set-ups. Finally, laser-etched graphics and a choice of anodised silver or black finish the set.
