- Wood absorbs vibration better than steel, aluminum or carbon, producing a uniquely smooth ride.
- The fatigue life of wood exceeds steel or aluminum, and approaches carbon
- Wood is not susceptible to crack propagation from dents like the metals, nor is it notch-sensitive or damage-concealing like carbon.
- Wood is as stiff pound for pound as the metals, even as it’s better at absorbing road vibration.
- And last but not least, wood is sustainable, recyclable, biodegradable, and has a tiny carbon footprint, while the primary production of steel, aluminum, titanium and carbon fiber are incredibly polluting and unfriendly to our environment.
