Good product if you're looking to replace your cassette. If you're Ok with black color, HG31 is the same and cheaper except the color. If you're building something new, get the HG400 with the 40 teeth max and an acera derailleur that climbs to 40!
This is my second purchase. I like the shimano products.
Good quality my Montara is now a all Shimano ride
Quick service with continuous contact considering with shipment.
Great upgrade from stock cassette, the last 34T ring will help in climbs.
