rear cassette is 14-17-21-26-32 and Front Chainrings are 52/39
it gives me a nice ratio range from 32 to 100
Yeah, a mtb will handle the 32 with no issues and a medium cage will handle all the chain wrap you are dealing with. There use to be old road derailers that would handle 36 and 38 big rear cogs,but they are hard to find and only work with friction.
