CS-HG400-9 Cassette 11-34t 9s

Shimano's Alivio-level CS-HG400-9 cassette covers a wide 11-34T range (11-13-15-17-20-23-26-30-34) that suits most trail and all-mountain 9-speed setups without hunting for a specialist wide-range cassette. Nickel plating fights off corrosion through a wet, salty riding season, and drilled cogs shave weight versus a solid-cog cassette in the same range — Shimano cites roughly an 11% weight saving over the HG50-9 at this range.

Built on Shimano's HG freehub body standard, it pairs cleanly with Shimano IG-chains for the smooth, quiet shifting Shimano's mid-range groups are known for, and it's rated durable enough to hold up under e-MTB torque loads, not just standard pedal-power use.
