Hey guys, this is my first post and hopefully not my last. I tried the search bar and couldn't come to any solid conclusions. My question is whether I should buy a wheelset that already comes with the freewheel and fixed cog, or to get it seperately? Also, how can I be sure what I am buying includes them, because often the description and photo do not match. I'd like to keep my budget at $300. I'm not too concerned with weight as sturdiness is more important. Also, I'm in Canada, any good online retailers?
