I bought a bike recently that has a 34 front 28 rear gear ratio. It is an Elfama E2500, which is a Korean brand I believe. It has a Shimano Claris (which is rated for up to 32 teeth) rear derailleur and an 8 speed 11-28 cassette in the back.
I would like to go with as big of a gear as possible for climbing, somethine like 11-32 which is the biggest I can find in an 8 speed. Something like this... http://goo.gl/eLbluH
Will this fit? Is there some other variable I am missing? Would it be possible to go up to a 10 speed cassette without changing too much on the bike?
