Here a a couple of pics of my bike setup.
Triple chainrings 52-42-30 and 12-36 cassette.
I had to swap out the Ultegra RD for a Deore XT with a hanger extender.
Big-big 52-36
Small-small 30-12 Almost touching, but isn't. Not a disaster, but I'd never deliberately shift to that combo anyway, as with the Big-big - it would only be for a few seconds until I realized I'd made a mistake.
