Description

See the weight transfer
Let the bike carry the weight.
Watch the scale reading change as the Backbone supports the bag. Your backpack stays with you while its weight gains a path onto the bicycle. The amount of support depends on your bike, bag, riding position, and adjustment.
What makes it Pro?
Three upgrades.
One complete setup.
Open each feature to explore the package.
Padded V Platform
A broad, padded support surface for your backpack or messenger bag, with height and fore–aft adjustment. The V top quick-releases from its shaft for easier stowing.
Cable-and-winch reinforcement
The Black-BONE system reinforces the Backbone support for heavier loads. Set the platform position first, then follow the cable installation and tensioning instructions. This is the hardware difference from Standard V.
Personalized setup review
After your Pro arrives, contact Support with your order number and photos of your bike and backpack setup. We will help review platform position and cable setup at no extra charge.
Follow the installation guide and all safety checks before riding; a photo review does not replace those checks.
See the adjustment
Set the platform first.
Position the V Platform beneath your bag before dialing in the Black-BONE cable-and-winch support. Height and fore–aft adjustment establish the fit.
Room for your bag. Less bulk to pack.
A wider platform.
An easy getaway.
The padded V top quick-releases from its shaft. Separate the two pieces to make the platform easier to stow between rides.
Release the top, lift it off the shaft, and stow the pieces together. Reattach securely before riding.

About the reflective decal
The reflective Backbone decal
Catches the light.
A subtle detail by day. A bright accent when light hits it after dark. The Backbone lettering is reflective.

The story behind Backbone
Road-born · rider-designed
A real problem.
Thousands of miles to solve it.
BikeBackbone began during founder Adam Keen’s long-distance bicycle journey from the Chicago area toward Panama. A heavy hiking backpack created the problem; prototypes built along the route became the product.
