The Praxis CS MTB DH9 Arms Only - 165 is engineered specifically for gravity riders and long-travel mountain biking enthusiasts who demand strength and reliability. Crafted from high-grade alloy with reinforced cross sections, these crank arms are built to withstand the toughest downhill conditions. Their robust construction ensures durability without sacrificing performance, making them ideal for intense rides on challenging terrains.
Inspired by the iconic "Down Hiller Commute" along the San Lorenzo river, the DH9 Arms capture the spirit of gravity riding with a design focused on purpose and resilience. The direct mount 3-bolt interface enables quick and simple chainring changes, giving you the flexibility to customize your setup with any 3-bolt ring, regardless of shape, size, or color. This versatility ensures you can optimize your bike’s drivetrain for any trail or race.
With compatibility for various bottom bracket standards including threaded 83mm BSA and press-fit PF41 options, the DH9 Arms offer seamless integration with most downhill frames. The adjustable chainline options of 57mm or 60mm, achieved through offset rings, allow you to fine-tune your drivetrain alignment for smooth shifting and optimal power transfer on every descent.
Are these crank arms compatible with my downhill bike?
The DH9 Arms support installation on most downhill frames with threaded 83mm BSA, PF41x104.5, and PF41x107 bottom brackets using Praxis M30 BBs.
Can I change the chainring size easily?
Yes, the 3-bolt direct mount interface allows quick chainring changes and supports any 3-bolt ring size or shape you prefer.
