The RNC BMX V3.141 Titanium Cranks are our lightest and most advanced titanium cranks yet, weighing only 16.9 oz / 479 grams.
The crank arms and spindle are CNC machined from USA-produced 6Al-4V titanium, heat treated and aged to approximately 170,000 PSI ultimate tensile strength.
A precision-machined Hirth joint securely connects the crank arms to the spindle while making installation and removal simple. No hammering or special installation tools — only a 12mm hex key is required.
A built-in adjustable threaded cone washer allows you to fine-tune bottom bracket bearing preload.
Flush-mount crank bolts are manufactured from Maraging 300 steel with approximately 300,000 PSI ultimate tensile strength.
