removing svn remotes

Hi, I have a svn repo cloned into a git repo. There are several remote refs that are there that I don't care about and don't want to fetch.

git svn fetch --fetch-all gets a bunch of stuff from branches I don't want git svn fetch requires I checkout the branches I care about before fetching

git svn fetch doesn't accept a branch name git remote rm isn't able to see the svn remotes

Is there a way to either:
1) get rid of the svn remotes that I don't want?
2) fetch only the remotes that I do want?

Thanks!
