Box Two Prime 9 11-50T Cassette

The Box Two cassette was where Prime 9 started. Originally conceived as an E-MTB product to deliver long service life and extra range over fewer gears, we quickly grew to enjoy its abilities on unpowered MTBs. All 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.
