BOX MTB Box Two Prime 9 E-Bike Cassette Black 12-50T

The Box Two E-Bike Cassette differentiates itself from its non-e-bike sibling by offering the high gears with more teeth to withstand the rigors of modern E-Bike riding. Adding an extra tooth to each of the three highest gears provides increased durability and decreased wear by distributing the load over a larger area! All sprockets are stamped from steel and subsequently, the larger ones are pinned to alloy spiders. Due to its provenance, this is, without doubt, the most durable cassette in the range and perfect for any E-MTB.
