5DEV R-Spec Crank Arms - MTB (Trail/Enduro) | Direct Mount (SRAM 3-Bolt) - black

R-Spec – Designed To Exceed The Standard

Brutally stiff, surprisingly light, and cleverly designed. These are the R-Spec crank arms from 5DEV. Precisely manufactured from aluminum 7050 and featuring a unique cutout architecture, they achieve an exceptional stiffness-to-weight ratio – the perfect prerequisite for direct and crisp acceleration. And when it comes to durability, the R-Spec crank arms also outperform other representatives of their weight class.

The slim profile with soft edges not only serves ergonomic purposes, but also ensures real everyday practicality without adding unnecessary grams to the construction. Not to mention the fact that aluminum is essentially more resistant to rock and ground contact than carbon. The design of the R-Spec crank arms fully follows the principle of functional material use: reinforcements where necessary and no unnecessary ballast. The triangular struts are the best example of this philosophy and additionally give the crank arms a distinctive look. But there isn't a single gram too many around the pedal thread either. Here, the minimalist approach also ensures more ground clearance, fewer pedal strikes, and correspondingly cleaner lines.
