Time to refresh your drivetrain! This is a brand new SRAM PG-850 PowerGlide cassette. It's an 8-speed cassette that's super common on a lot of mountain bikes, hybrids, and town bikes. The listing shows it comes in a few different gear ranges: you might be able to choose between an 11-28 tooth, an 11-30 tooth, or an 11-32 tooth setup (the seller's listing will specify which one you're getting). The wider the range (like 11-32), the easier your climbing gears will be. The model is PG850, and it has a metallic finish. The MPN listed is FW851132, and it has GTIN and EAN numbers: 00710845003967. It's made by SRAM, a top name in bike components. This cassette is listed as being for a 'Town Bike' type, but it fits any 8-speed hub that's compatible with SRAM/SHG cassettes. Perfect for when your old cassette is worn out, skipping, or you just want to change your gearing. A straightforward, quality replacement part to get your bike shifting smoothly again.
