Which is better 170mm or 175mm crank arm?
The Basics. XC – Possible sizing needed depending on ride lengths, but 175’s are what is recommended for more leverage. Trail/Enduro – 170mm crank arm length is the most commonly used size and is recommended to keep a good leverage ratio and have a bit more ground clearance due to having more travel.
Should I get shorter crank arms?
Moving to a shorter crank can improve: Comfort: A shorter crank length reduces range of motion at the knee (extension and flexion), hips, and low back. Aerodynamics: Going to a shorter crank will allow you to ride at a lower back angle which minimizes frontal surface area improving aerodynamics.
Is there a big difference between 170mm and 175mm cranks?
Whereas now 170 is ‘short’ 172.5mm is ‘normal’ and 175 mm cranks are very common. Still though, the difference between 170 mm and 175mm is less than 3% and leg lengths of bike riders vary by far more than that.
How do I know if I need shorter cranks?
Meanwhile, a longer crank allows a rider to push/pull harder ratios but makes it more difficult to maintain a high cadence. So the shorter cranks are recommended for those who engage in competitions with numerous changes of pace and for those who naturally pedal with a higher cadence.

What’s the best crank size for a trail bike?
Trail/enduro bikes should run 170mm cranks to still keep a good leverage ratio, but also have more ground clearance since the bike will typically have a bit longer travel and might be more likely to smash cranks in certain instances.
How is the arm length of a crank measured?
