Aizmugurējais zobratu bloks Shimano ALIVIO CS-HG400 9-speed

The CS-HG400 9-speed cassette supersedes the cassettes CS-HG61-9 and CS-HG50-9. With the larger hollow spaces in the sprockets, a weight saving of approximately 11% was achieved (Compared to HG50-9 at 11-34 teeth.) The cassette is available in different sprocket ratios and offers suitable gear combinations for 26/27.5 or 29er. HG cassettes are compatible with Shimano IG-chains and they care for silent and fluently gear shifting. HG sprockets guide the chain quickly and directly to the next sprocket without overdrive.
