Back in the day we drilled holes in our chainrings to make them lighter. The weight savings were minimal, but they sure looked cool. Our Drillium Crankset recaptures the look. It's based on the Grand Cru 110 cranks. 

They may look like a vintage crank, but are  made of modern high-strength alloy. The CNC cut chainrings feature the latest pins and ramps so they shift  faster and smoother. The crank arms have classically styled reliefs. Grand Cru cranks are cold forged. The chainrings are full 7075 alloy, so should be super durable. The  Q-factor is very low at 150mm.
