There is some wear around where (presumably) the seat bag straps have rubbed. Bag is in decent condition, clean inside, with some sun fading. There is a small section on the rear where the stitching is undone, but could be re-sewn or you could clip a light there. There is a small sealable pouch inside the main compartment. The bag clips into the bracket / tab on the seatpost.

Sorry, but I am not shipping outside the USA at this time.
Paypal preferred, or USPS money order.

Maybe it's the trippel talking, but I think I have the bike for this.
1995 Trek 5200, 27.2mm seatpost size.
The approximate centers of my tabs are 22mm and threaded for an M5 fine thread bolt. Could you confirm the spacing for the upper support is ~22mm?
THANKS
