Bought a Felt Z100 a couple weeks ago. Substancial improvement over the older Bianchi I was riding.
It has an 8 speed cassette, 12-25.
I'm in a part of the country with lots of hills, plus I weigh about 220. Also, riding in hot weather, I don't get as hot if I can pedal easier up a hill. Thinking about having the cassette changed out. So far, I've been able to ride up all the hills, but I've not tackled some of the longer, steeper ones here in the Arkansas/Missouri Ozarks.
LBS has a 11-30 cassette, will have to change out rear derailleur, so parts will be about $120. I know an 11-32 is made, just wondering if the 11-30 will give me enough improvement, to make it work the investment.
