WP_Query and pagination

gistfile1.php

  <?php 
  	    $paged = ( get_query_var('paged') ) ? get_query_var('paged') : 1;
		    $strapvert_blog_query = new WP_Query( 
		        array( 
		           'paged' => $paged,
		           'post__not_in' => get_option( 'sticky_posts' ),
		        )
		    ); 
	?>
		<?php if ( $strapvert_blog_query->have_posts() ) : ?>

			<?php /* Start the Loop */ ?>
			<?php while ( $strapvert_blog_query->have_posts() ) : $strapvert_blog_query->the_post(); ?>

				<?php
					  get_template_part( 'content', 'blog' );
				?>

			<?php endwhile; ?>

			<?php strapvert_content_nav( 'nav-below' ); ?>

		<?php else : ?>

			<?php get_template_part( 'no-results', 'index' ); ?>

		<?php endif; ?>

Problem is pagination does not work - so what am I missing?
