The SRAM Eagle XG-1275 12-speed cassette is a wide-range drivetrain component built for consistent shifting, strong durability, and reliable performance across demanding trail conditions. It uses FULL PIN construction to connect steel cogs with stainless steel pins, creating a solid structure that resists wear under load. The wide gear range supports steep climbs and fast sections, while the open design helps clear mud and maintain smooth operation in all conditions.Key Features and Benefits:FULL PIN construction with steel cogs and stainless steel pins: This design permanently links each cog using high-strength pins, creating a rigid and unified cassette structure. The added strength reduces flex under load, which helps maintain precise shifting. The result is consistent drivetrain performance and longer service life across repeated heavy useWide-range 10-50T and 10-52T gearing options: The large gear spread provides low ratios for steep climbs and high ratios for faster sections. This range allows smoother cadence control across varied terrain. The outcome is improved efficiency and reduced strain when riding mixed gradientsOpen cassette design: The spaced cog layout allows mud, dirt, and debris to clear quickly during riding. This prevents build-up that can affect shifting accuracy. The result is reliable performance in wet and loose conditions with less drivetrain wear over timeXD driver body compatibility: The cassette mounts to XD freehubs, which allows for a 10-tooth smallest sprocket. This design increases gear range without adding weight or bulk. The outcome is a more compact drivetrain with improved top-end speed capabilityOptimised shift progression: The cog sizing is arranged to provide smooth transitions between gears. This reduces abrupt cadence changes when shifting under load. The result is more controlled pedalling and consistent power transfer across all gearsDurable black finish: The coated steel cogs resist corrosion and surface wear from regular use. This helps maintain performance and appearance over time. The outcome is a cassette that holds up well in harsh riding conditions with less maintenance requiredA cassette like this supports stable cadence and dependable shifting across changing terrain. The wide gear range works with 1x drivetrains to handle steep climbs without losing efficiency on faster sections. The FULL PIN structure keeps the cassette strong under repeated load, while the open design helps maintain performance in poor conditions. These features combine to deliver consistent drivetrain function over extended use.This cassette is a practical choice for riders who want reliable shifting and long-term durability from their drivetrain. It supports a wide range of riding conditions and keeps performance consistent with minimal compromise.Specifications:Speed compatibility: 12-speedGear range: 10-50T, 10-52TCog sizes (10-50T): 10, 12, 14, 16, 18, 21, 24, 28, 32, 36, 42, 50Cog sizes (10-52T): 10, 12, 14, 16, 18, 21, 24, 28, 32, 36, 42, 52Cassette technology: XGCog finish: BlackDrivetrain configuration: 1xMinimum sprocket: 10TMaximum sprocket: 50T, 52TChain technology: Eagle(Not compatible with T-Type)
