Relative newbie here. Could someone give me a simple tutorial on comparing gearing on different bikes? Background is that I have a Jamis Quest with a 30/42/52 triple crank and a 12-23 cassette. I'm going to be doing some light weight touring in a fairly hilly area and have been thinking about a dedicated touring bike but really don't want to pay the scratch for a second bike that I'll probably only use a couple of times a year. One dedicated tourer I researched was the Volpe which has 28/38/48 and an 11-32 cassette. Does that type of setup give appreciably greater climbing ability? (I'm sticking to good roads and B&Bs so the added durability of a tourer is only a marginal consideration). Thanks

The real question is: "How easy of a hill climb gear do you need?"
Easiest hill climb gear
Current set up 35 gear inches
Current bike with 12/27 cassette + new chain 30 gear inches
With 11/34 cassette and mountain bike rear derailleur 24 gear inches
Volpe 24 gear inchesTo understand gear inches, think of a tricycle with that size front wheel. Bigger is faster, smaller is easier to pedal.

48-11 will be sufficient top speed for a touring bike.
28-32 will climb most mountains.I just bought a 28/38/48 crankset off a Giant CRX4 owner, he now has 11-30 cassette and 24/34/42 Crankset for touring Australia. 🙂
