The SRAM XG-1295 cassette is 95 grams lighter than the SRAM XG-1275 cassette. This significant difference is a key factor for riders looking to optimize their bike's weight and performance.
Understanding the Weight Difference
SRAM offers various tiers of its Eagle drivetrain components, with the XG-1275 and XG-1295 representing different levels of performance and material construction, which directly impacts their weight.
- The SRAM XG-1275 cassette is part of the GX Eagle group, designed to offer robust performance and durability for a wide range of riders. It weighs 450 grams.
- The SRAM XG-1295 cassette belongs to the X01 Eagle group, which focuses on lighter weight and more refined materials for competitive riders and enthusiasts. It weighs 355 grams.
This distinction in weight often comes from the manufacturing process and materials used. High-end cassettes like the XG-1295 often feature more extensive machining, different combinations of steel and aluminum alloys, or even a single-block construction to shed grams while maintaining strength.
Direct Weight Comparison
For a clear overview, here's a direct comparison of the two cassettes:
| Cassette Model | SRAM Eagle Group | Approximate Weight |
|---|---|---|
| SRAM XG-1275 | GX Eagle | 450 grams |
| SRAM XG-1295 | X01 Eagle | 355 grams |
| Difference | 95 grams |
Practical Implications of Weight
While 95 grams might seem like a small amount on its own, it can contribute significantly to the overall weight of a bicycle, especially when considering rotating mass.
- Performance: Lighter components, particularly in the drivetrain, can lead to quicker acceleration and reduced effort, especially noticeable during climbs or frequent speed changes.
- Rider Experience: For serious mountain bikers or racers, every gram counts towards a more efficient and responsive ride. The XG-1295 offers a noticeable upgrade for those prioritizing weight savings.
- Durability vs. Weight: The GX (XG-1275) cassette is often lauded for its excellent balance of durability and performance at a more accessible price point, making it a popular choice for trail riding. The X01 (XG-1295) sacrifices a bit of budget for superior weight savings, catering to riders who push the limits and demand the lightest possible setup.
