Here's the VO crank on a couple of bikes. 46/30 rings.
edit: same crank, different frame builds. Can't see needing more than one of these; but, i don't tour or hardcore off-road, or live in the high mountains.
It got paired with cross tires for my off-roading. Cino2016, Iron Horse trail, places on Olympic Peninsula, some trails off Hwy410, etc
The Harding, below, ran this wheelset
Sorry for fuzzy pic, it was wet-ish.
Also running the VO 48/34, 110bcd (so not to perjure the thread with a pic)
