Product Information
Full details
The SRAM Red BB30 Crankset is designed for competitive road cyclists and enthusiasts who demand elite-level performance and power transfer. By utilizing proprietary Exogram technology to achieve a hollow carbon construction, this crankset offers industry-leading stiffness-to-weight ratios for efficient climbing and sprinting. It is an ideal upgrade for those already utilizing SRAM Red 11-speed groupsets, though it requires a frame specifically designed for the BB30 bottom bracket standard.

FAQs
Is this crankset compatible with standard threaded (BSA) bottom brackets?
No, this specific model is designed for BB30 frames only.
Can I use this with a 12-speed groupset?
This crankset is engineered specifically for 11-speed drivetrain performance.
What is the benefit of the hidden bolt pattern?
The hidden bolt pattern allows for better integration of the chainrings into the spider, resulting in a cleaner aesthetic and improved structural efficiency.
How often should I check the chainring bolts?
It is recommended to check for proper torque every 500-1000 miles or whenever you perform a deep clean of your drivetrain.
Does this crankset come with a bottom bracket included?
No, the bottom bracket is usually sold separately to ensure you choose the correct bearings for your specific frame shell width.
Troubleshooting
Audible creaking coming from the bottom bracket area
Remove the crankset, clean the spindle and bearings, apply fresh high-quality bicycle grease, and reinstall to manufacturer torque specifications.
Poor front shifting precision
Verify that your front derailleur is a Yaw-compatible model and adjust the trim settings according to the SRAM service manual.
Pros and Cons
Pros
- Extremely lightweight hollow carbon design

Cons
- Exclusively compatible with BB30 bottom bracket shells
- Requires professional installation for precise bearing seating
- Limited to 11-speed drivetrain systems
Setup, Compatibility & Care
Installation of the BB30 system should be performed by a professional mechanic due to the specific tolerances required for bearing press-fitment. Ensure your frame has a clean BB30 shell before installation to prevent creaking.
Compatibility
- Bottom Bracket: Compatible only with BB30 shells.
- Drivetrain: Designed for 11-speed SRAM systems.
- Derailleurs: Optimized for SRAM Yaw front derailleurs.
Care Instructions
Regular maintenance involves wiping down the carbon arms with a damp cloth and mild soap. Periodically check the chainring bolts for proper torque settings using a torque wrench. Avoid using harsh chemical degreasers directly on the bottom bracket bearings to preserve their seal integrity.
