Grand Cru Drillium 110 Fluted Double Crankset
Back in the day, racers drilled holes in their chainrings to make them lighter. The weight savings were minimal, but they sure looked cool. Our Drillium Crankset recaptures the look while upgrading to modern manufacturing techniques and tolerances.
The arms and rings are cold forged from 7075 aluminum alloy. The rings are thicker so they don't flex as on classic cranks. The outer rings have modern shifting aids such as ramps and pins, so shifting performance is much improved. All stainless hardware with allen head nuts/bolts. Includes self-extracting aluminum machined dust caps and BB bolts.

This is a beautiful crankset. On a traditional seven speed freewheel, the shifting pins interfere with the chain line in the small ring and small cog even though I am using a 113 mm bottom bracket. So, I can't use my small cog while in the small ring. I still like the crankset as virtually no other cranksets offer compact gearing.
My intention was to put this VO Grand Cru Drillium crankset onto my venerable 1980 Raleigh Professional Mark V so that I could climb Mt. Baldy, the Santa Monica Mountains and the San Gabriel mountains which surround Los Angeles. I also thought it would make it possible for me to tackle Eroica California with perhaps a little less walking up Cypress Mountain. The low 34 front and 26 rear would be just what I needed. I was concerned about them fitting onto my Campagnolo Nuovo Record 113mm English bottom bracket spindle-I feared they would rub the right chainstay- but once fitted I was relieved to see that they had plenty of clearance. I used my Campagnolo bolts to secure them and run these without bolt covers. They look period and are so useful. Changes the rides I can tackle and that makes it even better. A perfect solution.
Bright, shiny, spinny!
