Specialized SRAM 2013 XX1 Chainring
The Specialized/SRAM 2013 XX1 Chainring is a bicycle chainring designed in collaboration with SRAM for the year 2013. It features 34 teeth and includes a spider (central carrier) with a Bolt Circle Diameter (BCD) of 76mm. This specification allows for determining the position and size of the screw holes that secure the chainring to the pedals.
The XX1 line is known for its high performance and precision in gear shifting, and this 34-tooth chainring is optimized for specific terrains and riding styles. It's crucial to note that the XX1 system is intended for use with a 1x11-speed configuration, meaning it is compatible with a single front chainring and an 11-speed rear cassette.
The component you're describing is a stock part from the Specialized Stumpjumper Hardtail. It features a narrow-wide tooth shape, indicating its design for 1x (single chainring) use. This tooth profile enhances chain retention, reducing the likelihood of chain drops during rides. The narrow-wide design alternates between narrow and wide teeth to match the chain links, providing a secure fit and minimizing chain movement. This type of chainring is commonly used in 1x drivetrains to ensure efficient power transfer and chain stability.
Here are the specifications for the described chainring:
Chainring Shape: Round
Drive Type: 1x (Single chainring)
Speed Compatibility: 11 Speed
Chainring BCD (Bolt Circle Diameter): 76mm
Weight: Not specified (please note that the weight information is not provided)
These specifications give details about the shape, drive type, speed compatibility, BCD, mounting, material, color, and weight (if available) of the chainring.
