???? What makes this chainring different
Your description is accurate, and here’s what it really means in practice:
???? 1. Thread-mount (NOT standard direct mount)
- This is a proprietary threaded interface
- It screws directly into the XX SL power meter spider
- No traditional 3-bolt or 8-bolt chainring mounting
???? Bottom line:
This will ONLY work with SRAM XX SL power meter spiders (Quarq-based)
⚖️ 2. Built for weight + stiffness
- SRAM removed the traditional spider/chainring interface to save weight
- Still maintains stiffness and reliability thanks to the threaded system
- Designed for top-tier XC / race bikes
✔️ This is why you see it on World Cup XC builds
???? 3. T-Type compatibility
- Works with SRAM Eagle Transmission (T-Type) drivetrains
- Optimized tooth profile for:
- Better chain retention
- Smoother shifting under load
????️ 4. Special tool required
- You must use the SRAM threaded chainring tool (TL0190)
- Standard chainring tools will NOT work
⚠️ Compatibility checklist (important)
Before buying, make sure:
- ✅ You have XX SL power meter spider (not standard crank)
- ✅ You are running SRAM Transmission (T-Type)
- ✅ You choose correct:
- Tooth count (32T, 34T, 36T, etc.)
- Offset (0mm or 3mm depending on your chainline)
