New guy needs help.
Hi everyone this is my first post here and boy do I need some advise. I recently purchased a used Schwinn Crosscut from the Bike Church in Philadelphia. I paid 125 plus and they let me exchange some of the parts with their used parts to make it more like a cyclo-cross bike. The only problem is I want to redo the bike the way I want it. Not completely new everything, but some of the components need to be replaced. The bike rides fine but these are the things I need help with.
1. Shifters - Ive been looking on jensonusa.com and they say 8,9, or 12 speed but my bike as I figured is a 21 speed. (3 front x 6 rear) Could I have some assistance in figuring out which ones will work.
2. Tires - There are 700-35c on the bike now but they are pretty worn so should I look for this same size when buying a new set? Is that a good size for road and light gravel?
Before anyone sais drop that crappy bike and buy new, I'm currently laid off and money is limited. I also dont care for top of the line because Im only riding, at the moment, for exercise and to save a little gas when possible. I approximate spending about $180 for everything, minus bike of course, but would like help getting there.
