Rennen Hive Mini BMX Crank Arms



SKU: N/A Category:
UltraLite Spider not included please check out it here
The Rennen Hive Mini Crank is the lightest square taper crank available. We have spent the last few months testing, optimizing and refining the design to create the most advanced mini crank on the market. Weight reduction is achieved through a honeycomb pocketing arrangement on the backside of each crank arm.
Material – As with all Rennen products we only use 7075-T6 Aluminum across all size ranges.
Size Range – 29 sizes of cranks, largest in the market from 90mm through 160mm in 2.5mm increments.
Lightest– We beat all the other brands in this department. When trying to break those lightweight build barriers every gram counts and we have done the work for you to set new records. Check out the following size/weights.
