i have a installed once but never used bicycle seat post rack w/ a Giant branded bag. i normally use a backpack but hated riding in the heat with a bag on my back due to sweat so i purchased this set. however the bag was too small for all my clothes i needed to carry to change out of and my lunch. the side pockets drops down on both sides to add more storage. just hoping to recoup some monies to buy more towels for my sweat. LOL.
will sell separately. $25 each bag or rack. BAG IS SOLD!!! just the rack avail.
