OUTER SHELL Top Tube Bag

The definitive top tube bag for both strap fastening and bolt-on

The top tube bag has been a staple of bicycle bags for many riders over the years. It provides easy access to your gear at all times without interfering with your ride.

Many times we have been asked, "Why don't you make an Outer Shell version?" ...... is finally ready!

Why did it take so long?

If you know the Outer Shell, you know why it took so long. There are many top tube backs on the market, but they didn't want to make the same one as the others, so they went through a lot of trial and error.
The resulting Outer Shell top tube bag is different from the rest!

It is very secure and does not wobble around while riding.
The zippers are also very difficult to open.
No more wondering, "Will it fit on my frame?" No need to wonder, "Will it fit on my frame?

This bag is a hybrid design that can be strapped on, bolted on, or both. Soft foam padding is built into the bottom to cover the bolts (or bolt holes when not in use).

Rubber coated straps and a non-slip rubber bottom are also included to provide excellent stability.

In addition, a specially designed plastic frame is built into the bag, so there is no need to worry about it losing its shape. The bag is also notable for its wide-opening separating zipper. The contents can be seen at a glance and can be smoothly taken in and out. It is weather resistant and has a convenient cable port.

It is compact, yet reliable.
