Explanation
At that time, the racers were trying to make a hole in the chainring to make it as light as possible. Of course the weight loss was minimal, but the bike certainly looked cool.
The Vero Orange Drillium Crankset is a unique crank with a cool look while using modern manufacturing techniques.
Cold forged from 7075 aluminum alloy. The ring is thick so it doesn't bend like a classic crank. The outer ring is equipped with modern shift aids such as ramps and pins, which greatly improves shift performance. All stainless steel hardware with Allen head nuts / bolts Includes aluminized dust caps and BB bolts. The dust cap serves as a self-extracting function when wristling the crank.
