Top Tube BTR Bag

A light waterproof bag that is small enough to be discreet but big enough for small items on a lengthy ride. two Velcro attachments with a soft tough rubber bottom to avoid scratches to your paint with a good zip to open/close the bag. very good value.

Really useful little bag

Works really well on my road bike. Can fit in my snack, pair of gloves, keys and phone easily.

Slimline Top Tube Bag

Fits really well and looks great on my bike. It won't hold a great deal but it perfect for small essential items.

Advertised to use nearer the handlebars but I use it near the seat pole. Super little thing for essential items
