Avalanche Crankset Max 140mm
What Is It?
The Avalanche Crankset Max 140mm is a replacement bicycle crankset designed primarily for junior and youth bicycles, where a shorter crank arm length is needed to match a child's leg length and pedalling biomechanics. The 140mm crank arms help younger riders pedal more efficiently and comfortably compared to adult-sized cranksets.
It is commonly found on children's mountain bikes and recreational bikes in the 20" to 24" wheel-size range.
