New Retro Looking Cranks

Looks like the guys at IRD scored a major coup.

The crank looks well made and is almost identical to Stronglight's model 106 crank at the spider arms, the arm fluting look more abbreviated though and they may not have a flute at the backs of the arm as the Stronglight 106 does an extra feature that makes it one of my favorite classic cranks. This IRD crank was posted/discussed before, but I don't remember what BCD the cranks were. It sure looks like a 144mm BCD, if it is, it sure was a brave move by IRD to make it these days when 144 is fading into the past fast, which makes this product focused on C&Vers......good for us!

I have them on my Bianchi. They're a really nice, well made crank from what I can tell. The track editions were $150 out the door.

Looks like the one in the third and fourth photos probably has a 110 BCD.

VO makes 50.4, 110 and 110/74 BCD cranks. Very classic looking, but with the advantage of 7075 alloy rings. The arms are obviously inspired by the Stronglight 49 arms. I've always thought the Stronglight and Nervar 50.4 arms looked cooler than the TA.

I believe they said 110 in the link. Which is good.

Defiant Track Crank

Designed to be reminiscent of the Campy Strada and Sugino Mighty cranks of the 1970's. But instead of CNC'ing from billet, we cold forge these before adding the fluting details. This makes for a stronger, more reliable design.


  • Cold forged and CNC'd 6061 T6 aluminum arms
    Polished finish
  • 144BCD spider
  • Fits JIS square taper bottom brackets (110mm for most set-ups)
  • 7075-T6 aluminum 46t chainring (CNC'd and polished)
  • 165mm, 167.5 and 175mm lengths
  • 600 grams

misery loves company! ...in the case of their freewheels it seems like LOTS of company. I can't help but notice that Harris Cyclery's website proclaims that if you want a ramped and twisted cog (HG style) freewheel that IRD is the only option. Its not. New SunRace freewheels have the HG style cogs as well.

well at least there's no moving parts on the crankset

That's true, but you might also get a crack that could lead to failure. I'm a bit wary of used NR/SR crank arms. I have one that is beyond filing to get rid of the crack, it is one of my nicest looking ones as well.

I know that's true, I've seen pictures, but in 40 years I've never experienced it.

I recently got hooked on SR 118 bcd triple cranks. Similar to the new IRC offerings and the rings fit Zeus. I'm going to make a Zeus triple.

I wish they had done cutouts instead of flutes on the spider arms like Sugino's Campy Record knockoff.

The 130 bcd crank with the 53/39 is tempting.... I could use a 39 t ring on my 14% grade home.

Zeus is 120mm BCD,, so you'll need to do some filing to make it fit.

That's kind of pricey for a pair of vintage looking cranks. I don't think I paid that much for the three pairs of NR/SR cranksets I've had this year. I still have two of the sets and a set of GS on my current bikes. The later SR were redesigned for the cracking issue incase your worried about that. I just think why buy a copy of something if you can buy the original for cheaper?

The '86/87 redesign did nothing to eliminate or reduce the sharp, corner stress riser that starts the cracks. Campagnolo did mill a curvature into the back of the arm near the stress point, but it doesn't solve the initial problem.

In fact, the redesign removed material that would otherwise slow down a crack in progress; hence, the '86/7 cranks are more likely to fail in comparison to their predecessors.

I think you are missing a point. If 42 or (41t if you are lucky) are fine, no problem. If you want to have the smaller ring sizes that 110 or 130 bcd will allow... these will get you that and keep a "Campagnolo aesthetic" . Not too bad, one could even drillium them and or remove the inner webs.
