There are two Backbone sizes?
Our new Backbones come in two sizes to fit whatever needs and budget you have. Our standard-sized Backbone is equipped with a 16-hole shaft so you can be rest assured that it has enough length and adjustability to fit your needs. It also allows for enough space for future compatible accessories like our pannier luggage rack called the “B-Rack” and a flag pole for increased visibility. So, when all our products and accessories become available you’ll be ready to build your Backbone the way you want with the functions you like. We also offer our baseline $44 Backbone Mini which is its smaller 10-holed twin. It extends about 9in from the seat post and has less room for adjustments and future Backbone accessories. If you have any doubt about which one will fit you then the standard-sized Backbone is a safe bet for $64. Join the Backbone movement.
