Alright guys or gals...I hope I have all the info to enlighten ya'll.
I am new to cycling and well I want to get better. I have a Felt F65 and don't get me wrong, I love this bike; however, I have a shimano hg hyper glide 12-23T cassette and this is a 9speed bike (I believe I am correct on that). I live in Greenville, SC and tried to attempt to do a Paris Mountain ride with my boyfriend...low and behold you can forget that! I was struggling so hard with the hill climbing. Can I swap out a cassette on this 9speed without changing anything else or what all do I need to change out??? Or will it just save me to go out and get a new bike...I just cannot part with this one, I love it.
I'm confused...this is all new to me.
