Description
Engineered for extreme trail performance and e-bike demands, the SRAM XG-1299 Eagle Cassette delivers a 10-52T gear range that conquers steep ascents and technical descents with precision. Built around SRAM’s proprietary X-Dome architecture, this 12-speed cassette combines aerospace-grade materials with innovative tooth profiling to optimize chain engagement and reduce friction by up to 30% compared to standard cassettes.
Key advantages:
✅ XD Driver Compatibility – Works seamlessly with existing SRAM 11/12-speed drivetrains using the same XD driver system (no additional parts required)
✅ Aluminum/Steel Hybrid Construction – Features a lightweight aluminum 52T mega-cog paired with hardened steel smaller cogs for maximum durability
✅ TiN Surface Treatment – Military-grade titanium nitride coating extends component life by resisting wear from loose gravel and wet conditions
✅ E-MTB Certified – Rigorously tested to withstand continuous high-torque output from electric mountain bikes
Performance comparison vs leading competitors:
| Specification | SRAM XG-1299 | Competitor Model |
|---|---|---|
| Weight (24-52T) | 335g | 398g |
| Largest Cog Material | Aircraft Aluminum | Steel |
| Shift Accuracy (Lab Test) | ±0.5mm | ±1.2mm |
| E-MTB Warranty | 3-year | Standard 1-year |
Ideal for:
▸ Enduro riders tackling prolonged climbs/descents
▸ E-bike commuters navigating urban hills
▸ XC racers seeking lightweight reliability
▸ Adventure cyclists crossing mixed terrain
The Rainbow™ color coating resists fading from UV exposure while maintaining structural integrity – perfect for riders who value both performance and aesthetics. With its optimized tooth geometry reducing chain slap by 40% on rough terrain*, this cassette ensures consistent power transfer whether you’re climbing at -5°C or descending at 40km/h in monsoon conditions.
Tested under ISO 4210 endurance standards
