This Blackburn pack will attach to your bicycle where the seat tube meets the top tube using 3 velcro straps.  It has just enough space to hold a wallet, repair supplies and a few power bars for a day out on the bike.  The bag has a padded shoulder strap to make carrying your bike more comfortable if you have to shoulder the bike for a short time.  Fuscia color with black trim and straps.  The finest materials and craftsmanship.
