have you thought about how the sprockets will line up? with a wider tire the
rear sprocket will naturally be way off to the left. the drive chain won't like that.
there are some offset sprockets out there, just not sure if they are that offset.
meaning for a 240 kit. cycle x's website shows this to some degree. go look
and think it over.
