With apologies; I searched and searched but can't find the link for a US-based shop that sells cranks that have been machined from triple to double, effectively creating a compact crank.
I would swear I saw it here, but I gave up swearing for lent. Told a friend about it recently but sent him to the wrong site.
I'm not trying to start an endless discussion about why this is or isn't a good idea, or questioning why it does or doesn't makes sense financially, ethically, or otherwise. [Although there does seem to be a shortage of OT posts recently - maybe everybody is out riding for a change?]

Thanks in advance,
No machining needed in my experience; just dismount the granny ring and leave off the bolts. The lateral spacing between sprockets is the same for doubles and triples, the latter just have one more sprocket. If the resulting positions are too far to the right, sometimes people swap the big ring to the other side of the spider (adding spacers as required for the smaller ring), but I'd avoid that if possible. Removing the granny ring won't make a compact crankset out of a large-circle one, in any event; you would have to move the bolt hole locations and possibly change the number of bolts if that was the real goal, and AFAIK no one does that, as the solid bosses to accomplish it are generally not present in the right places to make it work. -- Typoes are a feature, not a bug. Some gardening required to reply via email. Words processed in a facility that contains nuts.

We did that for a few years because Sugino had dropped their 110mm double. Now that Sugino has that as a standard product again in 170mm, 172.5mm and 175mm arms, we only machine them for 165mm

I just can't understand why anyone would spend money to make their crankset less useful. A you say, if you want a "compact double", remove the inner/granny ring, mount the suitable outer and inner (e.g., 50/34) and ride on. But, should a ride in big hill country arise, you still have the option of making it a triple again with the proper chainrings and, maybe, a longer BB/BB spindle.

The picture doesn't show the modified one, does it?
Yeah it does. Take a closer look. The one without the rings is modified. Look at where the small ring bolts on, there is less material there. It took me a while to see it too.

Yes, that's our machined and polishd surface on the left, triple on the right.
