Loko bag implements our vision of the ultimate top tube bag for  bikepacking 

Top tube bags are essential for bikepacking as they provide easy access to important items like snacks, tools, headphones, and medicine.
It's crucial for top tube bags to be one-handed operated and the 7Roads Loko bag ensures this. 

The 7Roads Loko bag is a lightweight and laconic-looking top tube bag that offers spacious storage and is mounted behind the head tube.

The 7R top tube bag has both a magnetic flap and zipper closure.
When riding on smooth paved roads, you can leave the zipper open for easy and fast access to the items inside. The magnetic flap provides a secure closure to keep everything inside.
However, when riding off-road, it is recommended to also close the zipper of the top tube bike bag for added protection."

For the Loko Bag we use ECOPAK™ or ULTRA™ fabrics 

These fabrics are waterproof, so with two layer flap and YKK AquaGuard zipper bag is very well water protected.
Also, we tape outer stitches for preventing a leaking

There are different ways to attach a Loko bag to your bike.
You can use movable velcro fasteners or bolt-on attachments.
Alternatively, you can lace it with a shock cord through the daisy chain on the bottom of the bag.
We've found it to be a very secure option.

If you choose the bolt-on system, we offer oval eyelets for the screw mounts to allow for some adjustments.
Alternatively, we can use round holes for a cleaner look.
