For more than seven years, Box Founder Toby Henderson has been trying to build a reliable 20-mil rear cassette hub without creating a new cassette standard, the problem was fitting durable bearings between the cassette body and the oversize axle. The rear Quantum hub overcomes this by using the type of one piece driver commonly found on freestyle hubs.

Each hubset includes a 1 piece, 16 tooth driver supported by 3 large, roller bearings. Inside the driver are 6 pawls, each with 2 teeth that engage a 60 tooth ratchet ring, meaning the hub has just 6° of engagement. The end result is a higher performing hub with fewer dead spots and less drag than others on the market.

Quantum front hubs are available only with 20mm axles, but the rears can be easily converted between 10mm, 15mm and 20mm axles. Each set includes a front and rear 20mm set-up. Additional spacers are included.
