For your PDQ bars (or anything similar) where you need something reliable to replace your old ones which have gone sticky due to the hours you've spent on the turbo, lost their 'memory' by going flat and / or shapeless due to the millions of hours you've done 'getting the miles in' ... or when you simply want to upgrade.  
Far better than the first generation grey / black ones.  These use a 'firmer' and thicker foam pad and are finished off with nice fancy stitching around the edges.  They've got velcro and adhesive sticky backing to keep everything in place.  Treat yourself. If you can't be fast ... be comfortable  ;-)
