BOX One Prime 9 X-Wide Cassette
The Box One cassette is a piece of art that brings together all the virtues of the Prime 9 philosophy and distills them into what we feel is our most defining product to date. A unique machined all-steel unibody lattice and alloy support disc have netted us a high-performing, simple, durable and lightweight cassette. With only 350 grams of weight we know that this is what the riders need. Enjoy the simplicity and ride this piece of history.
