Grand Cru Drillium 110 Fluted Double Crankset
Sold Out
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.

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!
I found it tricky to find a nice clean new 2 speed crankset that would look good on a vintage cycle so I imported this to Europe. Very happy I did, a nice clean vintage esthetic but without the hassle of old worn out parts. I was lucky to snap up one of the last black ones, looks and feels very light I feel it’s a great fit with my vintage aluminium frame, the finish looks great and seems like a durable quality part. You should keep the black one available!
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.
