Box Two 9 Speed Cassette

Originally conceived as an E-MTB product to deliver long service life and extra range over fewer gears, Box quickly grew to enjoy its abilities on unpowered MTBs.

All of this model's cogs 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.
