Ok, here's what you've done wrong:

1. Put it in the wrong section.
   
2. Haven't told us what changes you have in mind or why you want to change things or what you want to improve/what you think is wrong
   
3. By 'larger chainset' I guess you mean a bigger chainring? But you haven't told us what is on there already. And you haven't said why you might want one.
   
   

You need to make your questions more specific and provide a lot more information. It also helps if you can show that you have used the Search (^up there) to check if what you are asking has been asked before. The more you give the more you will get.
