Sugino XD2 Crank, Triple 46x36x24
Not good for 10- or 11-speed drivetrains!
This is the smartest and most versatile triple crank on the market, and is almost too smart and all-around good to even exist in these weirdo times. It's possible that Sugino wishes it could wipe it out with a new modern-style crank, but hasn't the resources to do that yet. So for now, everybody with a decent job should dig deep and buy at least two of them, just to encourage Sugino to keep making it.
It has about a 161mm to 165mm Q Factor (outside-to-outside width), depending on what length spindle on which you mount it. In the old days we'd consider that wide, but by modern standards it's smack dab medium.
On road bikes with straight (normal) chain stays, mount it on a 107-110mm square taper BB (JIS). If your bike has bowed-out chain stays like most mountain bikes, it might need a 113mm. Unlike most cranks, it also comes in a 165mm arm length.
110/74 bolt circle design.
Before installation, be sure to make sure all the chainring bolts are tight; and if a bolt and nut is a spinning, here's the special tool to keep it from doin so.
Available in your choice of lengths: 165mm, 170mm, 175mm. (172.5 has been discontinued by the factory)
And for all you torque-spec types: 320-390 inch pounds.
