I was looking for a nice, old school looking crankset that would work with a modern 2×10 drivetrain and found the Stronglight Impact double crankset. It fits my vision perfectly, have a look:
I really think this crank has the vintage look but is made for modern 9/10 speed chains. Forged alloy crankarms are made with 6061 silver anodized aluminum, with a BCD of 110 mm. Arms come in 165, 170, 172.5, and 175 mm lengths. Chainrings are also silver anodized aluminum with stainless steel screws, and have a lot of gearing variations: 46/36, 48/34, 48/38, 50/34, 50/36, 50/40, 52/39, and 52/42. Works with conical JIS square taper bottom brackets like the Tange Seiki UN 3922 or Shimano UN55 size 107 mm. It even comes with the Xtractor bolts which make it so you don’t need a crank extractor tool to remove the arms.
I purchased 165 mm arms with 48/34 gearing for my build.
Weight: 645 grams
Made in France.
Stronglight has been around for a very long time and even made many cranksets for vintage bikes. They trace their history all the way back to 1903, so I think they know how to make a crankset.
I really think this is a great option if you want a classic look for a modern drivetrain. And from my research it’s the only option offering 165 mm length. Plus, the price was cheaper than most of the modern cranksets for 9/10 speed. I got mine from The Cycle Clinic:
They have a good selection, price, and the shipping was fast! Also, they have done a good job answering all of my questions. I’m giving this a rating of 5 Gnomes I just think it looks great and feels of high quality.
I will update the review after install and after some miles. Really looking forward to finishing up my build, it should look amazing especially with this crankset.

I didn’t know Stronglight was still around. In the 70s, their Model 93 was the choice of top French bikes, Model 49 for the budget conscious. (Sort of like Dura-Ace vs Ultegra now.)
I’ve got old Stronglight cranks on my 70s Mercier. Glad to see you can still buy French components! If you rub off that logo, at a distance it could pass for Ultegra 6500/6600.
How do you like the old cranks?
They work just fine (like any crank) and have nice drillium chainrings. Full on retro!
