Is there difference between the Alta GPR 4, 5 & 6-Packs? What about the Alta 45ER 4 & 5-Packs?

The Alta GPR (General Purpose Rack) features the exact same body structure across all three rack configurations. The 45ER also has the same structure with its 4 and 5 packs. The only difference between the rack variations for all rack products (4-pack, 5-pack, 6-pack, 7-pack, & 8-pack) is the amount of baskets (and basket accessories) included with the rack. If the name of the bike rack is the same between the pack variations (GPR, 45ER, 76ER, Ocho, etc.), it has the same body structure.

As your needs change, the rack can be effortlessly upgraded to a higher capacity by adding baskets (up to 8 with the Ocho). To purchase additional baskets for your existing rack, go to the basket requests page and submit a request.

Please note that we only sell baskets to current rack owners who are registered in our system. If the rack was not purchased directly from us, please send us a picture of your rack and baskets to make sure we can accommodate your version of the rack. You may contact us about purchasing more baskets through our support page form, or order baskets through the basket request form mentioned.
