- Redesigned carbon 4-arm spider with a unified bolt pattern
- Unified bolt pattern allows for all 3 chainring standards 53/39, 52/36 and 50/34 to be built upon the same crankarms
- New design incorporates a 8-bolt pattern with a spider arm design that not only holds the chainring in place by way of the bolt but also supports the chainring and in doing so, increases system rigidity
- Lightened Ultra-Torque (UT), Hirth joint semi-axle bottom bracket spindle
- *Ultra-Torque outboard bearing cupsets or integrated adapters sold separately. Use CP-14025 for 68mm English or CP-14026 for 70mm Italian cupsets. Use CP-149xx for BB30, PF30 or BB86 press-fit adaptors
