Product Information

Full details

The DMR Sect Crankset is designed for aggressive mountain bike disciplines including dirt jumping, enduro, and all-mountain riding, offering a robust solution for riders needing maximum stiffness and reliability. Its key benefit is the high-strength construction featuring forged 6061-T6 aluminum arms and a heat-treated chromoly spindle, which ensures efficient power transfer during hard riding. A notable caveat is that while it is highly durable, it is optimized for specific performance needs rather than ultra-lightweight cross-country racing, so riders focused purely on shaving every gram may find it heavier than carbon alternatives.

FAQs

What bottom bracket is compatible with the DMR Sect?

This crankset is compatible with any bottom bracket designed for a 24mm spindle.

Can I use any chainring with this crankset?

You must use a chainring that features a SRAM 3-bolt direct mount interface.

Is this crankset suitable for Downhill racing?

Yes, its forged construction and chromoly spindle provide the durability required for downhill and gravity-fed riding.

How do I determine if my bike needs a Boost or Standard chain line?

Check your frame manufacturer's specifications for rear hub spacing; Boost is typically 148mm, while standard is 142mm or 135mm.

Does this crankset include a bottom bracket?

No, the bottom bracket is sold separately.

Troubleshooting

Creaking noise during pedaling

Remove the crank arms, clean the spindle and bottom bracket interface, apply fresh bicycle-specific grease, and torque the bolts to spec.

Chainline is misaligned

Verify if you are using the correct spacers provided in the hardware kit for your frame's specific Boost (52mm) or Standard (49mm) requirement.

Setup, Compatibility & Care

The DMR Sect utilizes a standard 24mm spindle, meaning it is compatible with a wide array of threaded and press-fit bottom brackets designed for 24mm axles. To install, ensure your bottom bracket is properly seated in the frame, slide the spindle through the drive-side, and secure the non-drive-side arm using the provided hardware. For chainring setup, use a standard SRAM 3-bolt compatible ring; verify your frame's chain line requirements before tightening the three mounting bolts to the manufacturer's specified torque. Regular maintenance should include checking the arm-to-spindle interface bolts for proper tension after the first few rides and wiping down the crankset with a mild degreaser to maintain the anodized finish.
