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.

Building out a Polyvalent Diamond and decided to put this crankset on it. It looks great (haven't tried it yet--still a long way to go on the build), but there is one small issue. When the bike shop put the crankset on, a cap covering the bolt came off. The shop was unable to put it back on! I still have the cap but neither they nor I could get it back on.
Ideas for solutions?
Great. Just stuck right now waiting on the wheelset before I ride.
So this is a small world. I bought these cranks as part of a build this last winter. I got a 2000 Waterford 2200 Team Mack Frame. Imagine my surprise when in the blog I saw that Igor had the same build in May of 2018! Velo Orange Grand Cru Drillium 34 x 48. New Velo Orange Sealed Bearing Bottom Bracket.

I needed a replacement compact crank for my 15-year-old aluminum frame road bike. My existing crank used the ISIS standard bottom bracket, and I had trouble sourcing a replacement. It made sense to go with the JIS square taper because that is easier to find. The crank seems very well made and the finishing is impeccable. The self-extractor is a really nice touch. Not sure I needed all the holes in the chainring, but it is fine.
My only complaint, and the reason I did not give 5 stars, is the issue with the shifting pin interference when cross-chaining the small chainring with the small rear cog. I don't intentionally ride in this gear combination- but have inadvertently done so a couple of times since installing. It is rather disconcerting because the pin catches the chain and tries to move it to the large chainring. It feels like you threw the chain. This is not a huge issue and I generally ride in the large ring anyway. Still, I have not experienced this with other cranks.
Important note- the cross-chaining issue alone would not stop me from purchasing this item. Trust me, this is a very nice crank!
