Ok, where's Ocotillo Ridge? Mapquest doesn't seem to helpful, on this. 11% sounds tasty.
I particularly like the Gates Pass ride: over the pass heading west to Old Tucson, then turn around and cross the pass again. Methinks I read somewhere that the climb headed to the east has portions around 12%. Or maybe my memory is disfunctional. At any rate it's a good grunt, and it can be topped off w/ a couple of laps up and down A Mtn., on your way back into town. Methinks that as far as effort goes, Gates Pass is a bit more "grunty" than Mt. Lemmon.
I'm weighing buying a cross bike just so I can do a Mt. Lemmon loop....up Catalina Hwy to Summerhaven, or thereabouts, and then down the dirt road, on the north side, to Oracle. That's be a great ride.
