I don't know too much about bike mechanics. I have a bike I bought last year with a Shimano FC-6400 crankset. There are 2 gears on the front, one which is marked 52T, and another that is marked 42T. There are 7 gears in the back. Is it proper to call the front gears the chainring, and the rear gears a casette? I would then refer to the bike as a 14 speed, correct?
I live on an island with really steep hills, and sometimes I need to get off the bike and walk it uphill. It also does not feel nice on my knees when I push myself up these hills. I was wondering if I replaced the smaller front gear to one with less teeth, and possibly smaller, would it be easier to pedal uphill? What are my options are for the smaller gear.
This is what my crankset looks like: http://velobase.com/ViewComponent.as...2-65f92ecdfcbe
Here is another post that mentions Shimano 600, but refers to 8sp : http://www.bikeforums.net/archive/in.../t-783006.html
Finally, will can I replace the 42T chainring with this 28T? : http://www.ebay.com/itm/Shimano-Biop...item19d01d400f
