IRD Defiant Cranks (Triples/Doubles) In The House



Interloc Racing Design (IRD) is company that started out in the mid-80's doing the mountain bike components, however recently they are better known for their 11-34 road cassettes, quality freewheels and other knick-knacks that larger manufacturers don't care to make anymore.

When we visited American Cyclery back in November, they had a test sample of one of these Defiant "Touring Triples" on a black Double Cross frame. It definitely caught our eye. Thought it was their track crank at first. We now have a few of these ourselves to sell on the Soma Shop. The arms are cold forged before the fluting details are added. The retro design does come with some old school eccentricities: These cranks need a wider BB than usual. For most bikes, it would be 115mm spindles for the doubles (53-39t or 50-36t) and 122mm for the triple. Not a huge issue. IRD makes those, too.
The chainrings are CNC'd, ramped and pinned for modern 9/10-speed shifting and buff-polished to match the crank arms.

These look really nice. Do you happen to know the q-factor? Also, the SOMA store lists the BDC as 110, but is the granny ring 74mm?

Also, any chance of offering the 25-deg silver Shotwell stems in 26.0mm? Pretty please.

I am in love with this crankset, and it absolutely kills me that they don't offer this set in 165mm. The shortest they do is 170. Yet they build their other cranks in 165mm. Go figure.

Velo Orange has a similar triple crank in 165mm length. 110/74 bolt pattern too. And its $20 less!

This is the same crank as the velo orange other than the logo. I can't see and haven't read of a single other difference. Does anyone disagree?

Velo Orange changed the machining on the crank arms.

These look nice! Does anyone have a suggested BB length for the Saga? 123mm?
